Streszczenie:

Straw fiber seedling pots are a promising substitute for plastic seedling pots. The mixing mode of straw fiber affects the mechanical properties of the raw material membrane of the seedling pot. To explore the processing technology of making the raw material membrane of the seedling pot with two kinds of plant fibers in a layered manner, the optimal combination of the process parameters of the raw material membrane of the seedling pot without additives in the production process was studied experimentally. Response surface methodology (RSM) was used to analyze the parameters (beating degree of unbleached softwood kraft pulp fiber, beating degree of wheat straw fiber, wheat straw fiber quality percentage content, and film grammage) with regard to the dry tensile index and Z-direction tensile index of the seedling pot body. The optimal process parameter combination with a certain dry tensile index and Z-direction tensile index of seedling pot raw material was obtained by using four factors and five levels of a quadratic regression orthogonal rotation center combination design parameter optimization experiment. The optimal technical parameters were optimized as wheat straw fiber quality percentage content 70%, film grammage 70 g/m2, unbleached softwood kraft pulp fiber beating degree 47–48 °SR, and wheat straw fiber beating degree 65–75 °SR. With the optimal conditions, the dry tensile index of the seedling bowl raw material film was between 21 and 22 N·(m·g−1), and the Z-direction tensile index was greater than 2.1 N·(m·g−1). Using wheat straw fibers and unbleached sulfite wood pulp fibers as raw materials for seedling pots, the raw material membrane of the seedling pots was made in a layered manner. The experimental study proved this feasibility. With this mixing process of raw materials, the straw fiber-based plant fiber seedling pot would meet the demands of a crop nursery after adding chemical additives. The research results provide a theoretical basis and technical support for the manufacture of the raw material membrane of the seedling pot body.

Streszczenie:

The bending toughness, strength retention, resistance to damage and bending stiffness of glass fiber mat, laminar composites under high strain rate impact loading conditions was studied. One of the main disadvantages of laminar composite materials is their poor interlaminar shear strength. Recent work has demonstrated a method of Z-direction reinforcement of these composites using electrostatic flocking techniques improve delamination resistance and fracture toughness without degrading the composites tensile strength or other in-plane properties when loaded quasi-statically. The Z-direction reinforcement is accomplished by electrostatically flocking short fibers perpendicular to and between the composite ply layers. In this study, composite samples were prepared using the flocking method in two fabrication modes by the; so-called Z-Axis wet and Z-Axis dry procedures. In this work, Z-direction reinforced composite panels (including a non reinforced control) that were previously projectile impact damaged were tested using established mechanical testing procedures. Damage areas were quantified and compared using image processing techniques. Three point bending tests were also conducted on these projectile impact damaged panels to determine and compare their bending toughness, strength retention and modulus. The results show that Z-Axis reinforcement by the flocking technique improves the overall mechanical strength and stiffness properties of glass fiber mat laminar composites. For example, Z-Axis reinforced projectile damaged and not damaged glass fiber mat composite laminates are found to have flexural strengths 9% to 15% higher and a flexural modulus (stiffness) 22% to 26% higher than comparable (not Z-Axis flock reinforced) glass fiber mat samples.

Layered carbon fiber composite performing microstructure was a part of multi-layer porous piping dielectric structure. At first a jet mechanism was put forward and researched for layered composite materials. The Z reinforcing fibers puncture was put to the layered composite structures. By the CFD simulation analysis, the feasibility of jet puncture was verified, the interlayer strength of the connection was increased and the Z bunch to the carbon fiber was eliminated, which laid theoretical foundation by enhancing the layered carbon fiber composite perform quality.

Streszczenie:

This paper presents a novel method for the ultrasonically assisted insertion of metallic z-pins into thermoplastic composites. Mechanical and microstructural investigations were carried out on glass fiber-reinforced polyamide and polypropylene specimens. The insertion of steel pins into thermoplastic composites led to microstructural changes that differ significantly from the known microstructure of z-pinned thermoset fiber-reinforced plastics. Optical microscopy showed an absence of notable fiber waviness and resin-rich zones around each pin. Instead, the fibers were predominantly deflected in the through-thickness direction by the high insertion forces arising during pin penetration. To gain an initial insight on the resulting properties of the z-pin/thermoplastic interface, the mechanical properties of z-pinned thermoplastic composites under mode I loading were investigated using pullout tests. For reference, the pullout behavior of thermoset carbon fiber-reinforced plastic specimens, reinforced with steel pins was determined too. Due to the poor bonding and lack of friction between the pin and laminate, the determined traction loads of the thermoplastic specimens are well below typical values achieved from pin pullout in thermoset laminates.

This work evaluated the use of conventional tests to show beneficial attributes of z-direction fiber orientation (ZDFO) for structural paperboards. A survey of commercial linerboards indicated the presence of ZDFO in one material that had higher Taber stiffness, out-of-plane shear strength, directional dependence of Scott internal bond strength and directional brightness. Laboratory handsheets were made with a specialized procedure to produce ZDFO. Handsheets with ZDFO had higher out-of-plane shear strength than handsheets formed conventionally. Materials with high out-of-plane shear strength had greater bending stiffness and compressive strength because of their ability to resist shear deformations.

We examined histochemically and immunohistochemically the distribution of B- and Z-DNA in the epithelium and terminally differentiating dog lens fiber cells. On the basis of anti-DNA antibody reactivity, qualitative and quantitative data on B- and Z-DNA in cells were determined. Anti-B-DNA immunoreactivity gradually declined throughout nucleated fibers, with a precipitous decrease at ∼90 μm. Anti-Z-DNA antibody binding decreased with a sudden loss of immunoreactivity at ∼90 μm. The pattern of anti-B- and Z-DNA staining correlates with the loss of α-crystallin immunoreactivity, the major lens crystallin, and decreased eosin staining of proteins. Germinative zone cell nuclei showed the highest DNA probe binding values, followed by the superficial fibers, central zone, middle fibers, and deep fibers. The presence of single-stranded (ss)DNA in deeper fibers was detected by anti-ss-DNA antibodies. This is indicative of DNA degradation. These observations suggest that a dramatic reorganization of lens fiber cells' supramolecular order occurs at ∼90 μm, the phase transition zone. (J Histochem Cytochem 45:1511–1521, 1997)

This research is to study the properties of pineapple leaf fiber reinforced polycarbonate composites (PC/PALF). Surface of pineapple leaf fiber (PALF) was pre-treated with sodium hydroxide (PALF/NaOH) and modified with two different functionalities such as γ-aminopropyl trimethoxy silane (PALF/Z-6011) and γ-methacryloxy propyl trimethoxy silane (PALF/Z-6030). The effects of PALF content and chemical treatment were investigated by Fourier transform infrared spectroscopy, Scanning electron microscopy and mechanical testing. The modified pineapple leaf fibers composite also produces enhanced mechanical properties. Young’s modulus is highest in the case of the PALF/NaOH composites. The PALF/Z-6011 composites showed highest tensile strength and impact strength. In thermal property, the results from Thermogravimetric analysis showed that thermal stability of the composites is lower than that of neat polycarbonate resin and thermal stability decreased with increasing pineapple leaf fiber content.

This study investigates the effects of Z-pinning on the delamination performance in opening and shear loading modes in woven fabric reinforced / epoxy composite materials, as well as the effects of friction between specimen crack faces and the Z-pin failure mechanisms involved in mode II delamination. Mode I and mode II delamination tests are carried out on Z-pinned unidirectional (UD) and woven laminates. Both UD and woven laminates exhibit enhanced delamination resistance and crack propagation stability through Z-pinning. The effects of various structural and Z-pin parameters on the mode I and mode II delamination behaviour are separately assessed. The 4ENF testing configuration is deemed as the appropriate mode II configuration for the testing of Z-pinned laminates. A new basic friction rig is used to measure the friction coefficient between crack faces in woven laminates. An additional friction effect attributed to fibre architecture is identified. A specially designed delamination specimen is used to overcome the difficulty of accurately measuring crack propagation in Z-pinned woven fabric materials and aid data reduction using the available analytical methods. The failure mechanisms involved in the mode II delamination of Z-pinned laminates have been investigated with the implementation of a new test. Z-pins fail under shear loading through a combination of resin crushing, laminate fibre breakage, pin shear, pin bending and pin pullout. The balance of the failure mechanisms is shown to be a function of the crack opening constraint, material type, stacking sequence, Z-pin angle and insertion depth to Z-pin diameter ratio. Z-pin and material parameters influencing Z-pinning quality are identified, categorised and quantified. The importance of controlling Z-pin insertion depth is underlined and updated manufacturing procedures are proposed. Partial pinning appears as an advantageous alternative. A reduction in in-plane stiffness and in-plane strength in UD and woven fabric composites is measured, whilst no significant change of in-plane shear stiffness of UD materials is observed. A reduction in the fibre volume fraction is the single most important parameter affecting the in-plane stiffness. The performance of a Z-pinned sub-structural component is investigated. Enhanced loading carrying capacity and damage tolerance is achieved through Z-pinning.

Streszczenie:

Z-pinning is a through-thickness reinforcement technology for polymer composite materials that has been developed and commercialised over the past fifteen years. The through-thickness reinforcement of composites with thin metallic or fibrous pins aids in suppressing delamination, improving impact damage tolerance and increasing joint strength. Z-pins are applied to the composite part during its manufacture. Pins are embedded within sheets of foam and placed over the unconsolidated part. Subsequently, the foam is compacted and the pins transferred into the part, which is usually an uncured prepreg. In this manner, large numbers of pins can be inserted quickly and easily. The pinned composite is then cured using conventional processes. The use of z-pins is currently limited to several high performance composite structures, most notably Formula One racing cars and F/A-18 E/F (Superhornet) fighter aircraft, although the technology has potential applications in a d iverse variety of aerospace and non-aerospace composite structures. A limited understanding of the mechanical performance of z-pinned parts under high load and fatigue loading conditions currently hinders the application of z-pinned composites. The aim of this PhD project is to investigate the mechanical properties, strengthening mechanics and failure mechanisms of z-pinned carbon/epoxy laminates and joints. The effect of z-pin reinforcement on the tensile and flexural properties of laminates under monotonic and fatigue loading is studied. The sensitivity of these properties to the volume content and diameter of the z-pins is systematically studied by experimentation and analytical modelling. This PhD also evaluates the efficacy of z-pins in improving the load-bearing properties of carbon/epoxy lap joints. Improvements to the room temperature and elevated temperature properties of z-pinned lap joints under monotonic and fatigue tensile loading were determined. The effect of strain rate on the load-bearing properties of z-pinned lap joints was also evaluated. A further aim of the PhD project was to assess the z-pin manufacturing process and the microstructural damage caused by that process. The outcome of this study augments the analysis of the me chanical properties of z-pinned laminates and joints.

Streszczenie:

Effective treatment of carbon fiber components to improve delamination resistance is vital to the application of such materials since delamination is one of the biggest concerns regarding the use of composites in the aerospace sector. Due to the significant application benefit gained from increased stiffness to density ratio with composite materials, innovative developments resulting in improved through-thickness strength have been on the rise. The inherent anisotropy of composite materials results in an added difficulty in designing structural elements that make use of such materials. Proposed techniques to improve the through-thickness strength of laminar composites are many and varied; however all share the common goal of improving inter-laminar bond strength. This research makes use of novel materials in the field of wet flocking and Z-pinning. Cellulose nanofibers (CNFs) have already demonstrated excellent mechanical properties in terms of stiffness and strength, originating at the nano-scale. These materials were introduced into the laminate while in a sol-gel suspension in an effort to improve load transfer between laminate layers. The effect of CNFs as lightweight renewable reinforcement for CFRPs will be investigated. Carbon nanotube (CNT) additives were also considered for their beneficial structural properties.

Nesta dissertação, propomos um método que combina a técnica de varredura-Z e a luz branca supercontínua gerada em uma fibra fotônica para caracterizar o espectro de não-linearidades de amostras. O espectro não-linear fornece informações cruciais a respeito da característica, da origem e do potencial da não-linearidade para aplicação em dispositivos. Neste sentido, a luz branca supercontínua aliada à técnica de varredura-Z vem permitir uma rápida determinação de espectros numa banda larga. Neste trabalho, a luz branca foi gerada numa fibra fotônica comercial bombeada por pulsos de femtossegundo de um oscilador laser de Ti:safira. Tanto os lasers de femtosegundo quanto as fibras fotônicas estão se tornando cada vez mais acessíveis. Ademais, a técnica de varredura-Z é um método bastante conhecido para a determinação de não-linearidades devido à sua simplicidade e precisão. Dessa forma, aliamos essas vantagens para fazer um aparato simples, compacto e de baixo custo. Em geral, a determinação do espectro de não-linearidades necessita de sistemas lasers complexos que possam sintonizar o comprimento de onda. O método de varredura-Z de luz branca desenvolvido aqui foi usado para medir o espectro não-linear do corante disperse red 13 (DR13) em metanol. Esse corante possui um efeito não-linear absortivo (absorção saturada) bem caracterizado, sendo um bom material não apenas para calibração, mas também para testar nosso sistema experimental. Os resultados experimentais comprovaram a viabilidade do sistema para caracterização de amostras com efeitos não-lineares absortivos intensos.
In this dissertation, we proposed a method that combines the Z-scan technique and the white-light continuum generated by a photonic crystal fiber to characterize the nonlinear spectrum of materials. The nonlinear spectrum provides crucial information on the characteristic, the origin and the potential of the nonlinearity for devices application. In this sense, the white-light continuum allied to the Z-scan technique allows fast spectra determination in a broad spectral range. In this work, the white light was generated in a commercial photonic crystal fiber pumped by femtosecond pulses from a Ti:sapphire laser oscillator. Both the femtosecond lasers and the photonic crystal fibers are becoming more accessible. In addition, the Z-scan technique is a well-known method for nonlinearities determination due to its simplicity and precision. In this way, we merged these advantages to make a simple, compact and low-cost apparatus for studying nonlinear samples. In general, the nonlinear spectrum determination requires complex laser systems which are able to tune the wavelength. The white-light Z-scan method we developed here was used to measure the nonlinear spectrum of disperse red 13 (DR13) dye in methanol. This dye presents a well-characterized absorcive nonlinear effect (saturable absorption), being a good material not only to calibrate, but also to test our experimental setup. The experimental results confirmed the viability of the setup for characterizing samples with strong nonlinear absorption effect.

In the past, my work was focused on transferring the flat visual element into the space. I turn away from this concept, because as my Master's thesis I chose a Labyrinth. A labyrinth is not primary flat visual element. My final work is free artistic interpretation of this theme. My work based on classical craftsmanship techniques, which I am using in the new way in my work. I understood this theme labyrinth as an something very personal and individual. Because of this, I decide to create sculpture which will fit in to the gallery space and also the space of everyday life. My expression of the Labyrinth has cube shape. The entire sculpture is stitched inside, this stitch create the inside space. In one way this inner space is open and we are free to look inside, in the other hand center of the sculpture is hidden. I want to express a feeling of secrecy, and create tension between outside and inside space of the sculpture.

This diploma thesis deals with the separation of aerosol particles on membranes from polypropylene hollow fibers. As a source of particles, a desktop 3D printer using polymer filaments was used. Filtration efficiency and a pressure drop on a hollow polypropylene fiber membrane and a high efficiency particulate filter (HEPA filter) were monitored during filtration of particles from 3D print using filaments of acrylonitrile butadiene styrene, acrylonitrile styrene acrylate, polylactic acid and polyethylene terephthalate glycol at nearly the same air flow. The results achieved by both filer media are then compared and discussed. The results show that the hollow fiber membrane achieves better filtration efficiency at higher particle concentrations, while using the less emitting materials, the efficiency of the HEPA filter was higher or the same. The total filtration efficiency calculated from all experiments with all filaments was higher for the hollow fiber membrane with higher pressure drop at the same time.

Membrány z dutých vláken jsou široce využívány v aplikacích týkajících se úpravy kapalin jako např. při čištění odpadních vod, v membránových kontaktorech a bioreaktorech, membránové destilaci apod. I když jsou často využívány při separacích směsí plynů, je jejich použití pro mechanickou filtraci aerosolů velmi vzácné. Tato práce se zabývá filtrací vzduchu pomocí polypropylenových membrán z dutých vláken včetně jejich filtrační účinnosti, tlakových ztrát a také zanášením při dlouhodobé filtraci. Filtrační účinnost byla proměřena za použití různých aerosolů jako TiO2 a síran amonný. Tlakové ztráty byly měřeny při různých konfiguracích, tj. různé filtrační ploše a průměru vlákna membrány. Zanášení membrán bylo testováno použitím normovaného prachu definovaného normou ANSI/ASHRAE 52.2. Predikční modely pro filtrační účinnost a permeabilitu/tlakovou ztrátu membrány byly aplikovány na parametry membrán z dutých vláken a porovnány. Tyto membrány mají velikost pórů kolem 90 nm a poměrně nízkou porositu a tím vysoký potenciál pro separaci nanočástic ze vzduchu. Dále byla provedena analýza filtračního koláče a vyhodnocení energetických nároků a porovnány s teoretickými modely. V závěru práce je nastíněn odhad ceny životního cyklu při filtraci pomocí těchto membrán.

The main aim of this work is the experimental verification of theoretical patterns, which are involved in the transport of heat and moisture in fibrous materials, especially the influence of fibers thickness and density of the fibrous materials. To widen outputs of the work were selected different kinds of natural fiber materials of vegetable and animal origin. The results of the work should help to optimize the production processes of natural insulation materials considering their optimal thermal properties. From the data collected are deduced general conclusions to better understanding the behavior of these materials.

This method of ultimate limit state design will be applied to determine the ultimate limit state of reinforced concrete column loaded by a combination of "N + M", the normal force and bending moment. Specifically, I will solve a circular reinforced concrete column with and without the effect of wrapping unidirectional carbon fiber fabrics and comparing the theoretically determined values with the values determined by experiment, which is carried out at the Institute of Concrete and Masonry Structures Faculty of Civil Engineering of the Technical University in Brno.

AbstractWound-healing phenomena are the result of a cascade of complex biochemical events that can be categorized into four general overlapping phases: coagulation, inflammation, proliferation, and remodeling. Significantly, all four phases of wound healing are influenced by both intrinsic and extrinsic mechanical forces. These mechanical forces provoke chronic inflammation of the dermis, namely, the unceasing influx and activation of inflammatory cells, the persistent generation of blood vessels and nerve fibers, and the constant production of collagen by the activated fibroblasts. This chronic inflammation blocks the conversion of the granulation tissue into dermis-like tissue by the remodeling process and results in an immature hypertrophic scar that is red, elevated, hard, and painful. These observations suggest that, to prevent pathological scarring after surgery, it is necessary to ensure that the sutures cause the wound edges to adhere to each other without any tension, even when strong extrinsic forces are placed on the wound. This will allow the granulation tissue to convert smoothly into dermis-like tissue, thereby yielding minimal scarring. Another way to prevent pathological scar formation in high-tension areas is to use zigzag suturing techniques such as the Z-plasty.

To understand how eye muscles move the eyeball, it is necessary to understand the geometry of the eye and the functions of the muscles. The eyeball rotates about three axes: horizontal, vertical, and torsional. These axes intersect at the center of the eyeball. Eye rotations are achieved by coordinated contraction and relaxation of six extraocular muscles—four rectus and two oblique—attached to each eye. The action of the muscles on the globe is determined by the point of rotation of the globe, as well as the origin and insertion of each muscle. Recent evidence suggests that the muscles also exert their effects on the globe via the extraocular muscle pulleys. Considering that we make at least 100,000 saccades alone each day, it is not surprising that many extraocular muscles are very resistant to fatigue. Extraocular muscles are also different from other skeletal muscles in many respects. For example, eye muscle fibers are richly innervated, and each motoneuron innervates only 10–20 muscle fibers, the smallest motor unit known in the body. Extraocular muscles also have more mitochondria and a higher metabolic rate than other skeletal muscles. Thus, extraocular muscles are one of the fastest contracting muscles. This property allows animals to shift gaze swiftly, so that they can avoid approaching predators or detect prey in the vicinity. The unique immunologic and physiologic properties of extraocular muscles may also explain why they are more susceptible to certain disease processes, such as Grave’s disease and chronic progressive external ophthalmoplegia, but more resistant to others such as Duchenne’s dystrophy, which mainly affects skeletal muscles in the rest of the body. The eyeball rotates about three axes: x-axis (naso-occipital or roll axis), y-axis (earthhorizontal or pitch axis), and z-axis (earth-vertical or yaw axis). Ductions refer to monocular movements of each eye. They include abduction, adduction, elevation (sursumduction), depression (deorsumduction), incycloduction or incyclotorsion, and excycloduction or excyclotorsion (see table on opposite page). Versions refer to binocular conjugate movements of both eyes, such that the visual axes of the eyes move in the same direction. They include dextroversion, levoversion, elevation (sursumversion), depression (deorsumversion), dextrocycloversion, and levocycloversion (see table).
