Texto completoBiocomposites are fiber-reinforced materials from renewable resources. These materials are an alternative to fiberglass or carbon reinforced composites. Indeed, their lightweight and interesting mechanical properties give them a growing interest in sectors such as building (decking, garden furniture) or automobile (door panels, dashboards). However, humidity, temperature and UV radiation are parameters that can compromise the physicochemical stability of biocomposites.The main objective of this thesis is to assess the biocomposites durability in their main conditions of use. For this purpose, these materials have been exposed for one year outdoors (deck boards) and under windshield glass (dashboards). The results showed that the mechanical performance of biocomposites was affected and greatly influenced by the type of exposure. On the other hand, the differences in color and crystallinity variations that differ between the two exposures suggest different degradation mechanisms that are very dependent on the conditions of use.Since biocomposites can be used in environments such as the passenger cabin, they can also be sources of pollutants in indoor air. The study of emissions of volatile organic compounds (VOCs) by biocomposites during their ageing under windshield glass allowed generating data necessary for the evaluation of the impact on the car indoor air quality of these new materials. However, the drastic increase of VOCs surface concentration during exposure suggests that weathering strongly affected biocomposites due to the sensitivity of the structural components of plant fibers to exposure conditions.Understanding of the degradation mechanisms can be carried out through the interpretation of the causal links between mechanical and microstructural properties, VOC emissions and visual appearance. Statistical treatment by Principal Component Analysis (PCA) revealed the links and relationships existing between the quantitative parameters.Natural weathering often requires long time of exposure for an efficient perception of the materials degradation. Thus, accelerated ageing in laboratory is more and more carried out in industry for time saving. In order to verify the representativeness of the degradation mechanisms occurring during exterior weathering by weathering chambers, a comparative study between the exterior aging and the artificial aging was carried out

Texto completoThe aim of this study was to investigate the effect of polypropylene and steel fibres on the behaviour of concrete subjected to high temperature. Polypropylene fibres were added to the studied concrete mixes in order to improve the concrete thermal stability. Steel fibres were added to the studied concrete mixes in order to improve the concrete residual mechanical properties. News concretes mixes were then designed by adding a cocktail of polypropylene fibres and steel fibres in order to improve both the thermal stability and the residual mechanical properties of the studied concrete. Four groups of concrete mixes were studied: - concretes without fibres, - concretes with polypropylene fibres, - concretes with steel fibres, and - concretes with a cocktail of polypropylene and steel fibres. Three water/cement ratios were used: 0.30, 0.45 and 0.61. The concrete specimens were subjected to various heating – cooling cycles from the room temperature to 150°C, 300°C, 450°C and 600 °C. The heating rate was fixed at 1 °C.min-1. The amounts of fibres in the concrete were 0.11%, 0.17% or 0.22% in volume for polypropylene fibres and 0.25%, 0.38% or 0.51% in volume for steel fibres. The amounts of fibres in concrete with a cocktail of polypropylene and steel fibres were 0.49, 0.60, 0.62 and 0.73%, in volume. The thermal stability, the initial and residual mechanical properties (compressive strength, tensile strength, modulus of elasticity), the porosity and the mass loss of the studied concrete mixes were investigated.This experimental study shows a way to design a concrete mix in order to improve both the thermal stability and the residual mechanical properties

Texto completoNowadays, biocomposite materials are booming and will be a growing end-of-life issue for the future. They are based on a thermoplastic matrix (oil-based or bio-based) reinforced with vegetable fillers or fibers. Consequently, the study of their end of life through recycling, composting and incineration is a scientific and technologic challenge.The first goal of this thesis is to study the reprocessing end of life (successive injection and grinding cycles) of polypropylene (PP) based biocomposites filled with wood flour. The impact of the wood particle size and a coupling agent was assessed. Thus, a very good mechanical stability was observed up to 7 reprocessing cycles despite some degradation from the material components. Then, the reprocessing after artificial or natural UV weathering was carried out. The major trend is a “regeneration” phenomenon of mechanical properties after reprocessing in spite of strong degradations after UV weathering. Moreover, the addition of wood filler tends to restrain the PP photochemical degradation.The second goal is to study the end of life of polylactic acid (PLA) based biocomposites reinforced with flax fibers. The impact of the composition, the processing technic and humidity weathering on the reprocessing was assessed. Similar “regeneration” phenomena were observed leading to conclude to the beneficial effect of reprocessing. Then composting and biodegradation aspects were investigated. Heat release rate measurements enabled to estimate the incineration potential which could be linked to the PLA degradation rate

Texto completoNatural fibres fulfil all the requirements in order toreplace inorganic fillers in thermoplastic composites. Naturalfibres are inexpensive, renewable, biodegradable, present lowerdensity and their mechanical properties can be compared tothose of inorganic fillers. However, several disadvantagesappear when natural fibres are used for composites. First ofall, the poor compatibility between the hydrophilic fibres withthe hydrophobic thermoplastic matrix leads to a weak interface,which results in poor mechanical properties. On the other hand,the hydrophilic nature of the fibres makes them very sensitivetowards water absorption, which leads also to the loss ofproperties and the swelling and dimensional instability.
In order to enhance the compatibility fibre-matrix, thefibres were chemically surface modified by five differentmethods: a) graft copolymerisation withpolypropylene-graftedmaleic anhydride copolymer (PPgMA), b)modification by PPgMA during processing, c) modification byorganosilanes, d) acetylation, e) modification with peroxideoligomers. Modified fibres led to improved mechanicalproperties and thermal behaviour when used in composites withpost-industrial polypropylene (PP) containing ethylene vinylacetate copolymer (EVA). Modification with peroxide oligomersshowed very promising results, but modification with PPgMA waschosen for further preparation of composites due to itssimplicity.
Two sets of composites were prepared using two differentpolypropylene types as matrix: virgin polypropylene (PP) andthe above mentioned post-industrial polypropylene (PP/EVA).Four different types of cellulosic fibres were used as fillers:cellulose fibres from pulping, sisal fibres, coir fibres andLuffa sponge fibres. The mechanical properties of thecomposites were dependent mostly on the fibre loading andslightly on the type of fibre. The fibers changed thecharacteristics of the material leading a higher stiffness buta lower toughness.
Water absorption of composites was studied at threedifferent temperatures: 23°C, 50°C and 70°C. Thewater absorption kinetics were studied and it was found thatwater is absorbed in composites following the kineticsdescribed by the Fickian diffusion theory. After absorption, animportant loss of properties was observed, due to thedestruction of the fibre structure due to the waterabsorbed.

Texto completoUntersuchungen zum mechanischen und thermischen Verhalten sowie zur Benetzung von Jutefasern im Ausgangszustand, nach Entwachsen und nach Oberflächenmodifikation, mit dem Ziel einer Verwendung als Verstärkungsfasern in Verbundwerkstoffen. Untersuchungen zum mechanischen und thermischen Verhalten sowie zur hygrothermischen Alterung von Jute/Polypropylen (PP) Verbunden. Einfluss des PP-Typs, der Modifizierung der Matrix mit Maleinsäureanhydrid gepfropftem PP und des Faservolumengehalts.Untersuchung der Grenzschicht in Jute/Epoxidharz Verbunden in Hinblick auf die mechanischen Eigenschaften nach Alkalibehandlung und Oberflächenmodifikation der Jutefasern. Jutefasern haben gute spezifische mechanische Eigenschaften. Die Einzelfasereigenschaften unterliegen der bei Naturfasern üblichen Streuung der mechanischen Eigenschaften. Im Gegensatz zu konventionellen Verstärkungsfasern (Glas, Carbon) nimmt wachstumsbedingt mit zunehmendem Faserquerschnitt die Festigkeit tendenziell zu. Faseroberflächenbehandlungen verbessern die Benetzbarkeit, erhöhen die thermische Stabilität und reduzieren die Feuchteaufnahme sowie den Diffusionskoeffizient. Jute/Polypropylen-Verbunde Chemische und physikalische Wechselwirkungen zwischen Faser und MAHgPP nach optimierter Kopplerauswahl verbessern in Abhängigkeit vom PP-Typ die Grenzflächenscherfestigkeit und die mechanischen Eigenschaften. Durch Einbeziehen der Grenzflächeneigenschaften können mit einer modifizierten Mischungsregel die Zugfestigkeiten der Verbunde beschrieben werden. Jute/Epoxidharz-Verbunde Faseroberflächenbehandlungen mit Natronlauge, Organosilanen, Epoxiddispersionen und deren Kombinationen führen zu verbesserter Benetzung, reduzierter Wasseraufnahme und verbesserter Haftung sowie verbesserten mechanischen Eigenschaften in Jute/Epoxidharz-Verbunden
