For this thesis, research was performed on CFRP bonded composite lap-joints with one and two continuous laminas through the lap. Composite wraps used to retrofit existing structures use lap joints to maintain their integrity. The use of composites for retrofitting structures has many advantages over traditional methods, such as steel jacketing, and is becoming more widely accepted in the structural engineering industry. While much literature exists documenting the performance of composite wraps as a whole when applied to concrete columns, less information is available on the behavior of the lap-joint of the wrap. Developing a better understanding of how the lap-joint behaves will help researchers further understand composite column wraps. This research sought to determine what affect continuous middle laminas may have on the stiffness of lap joints and whether or not stress concentrations exist in the lap-joint due to a change in stiffness.

O objetivo deste trabalho foi produzir, caracterizar e avaliar o comportamento mecânico de um compósito de matriz termoplástica (ABS) reforçado por fibras de carbono para uso futuro em manufatura aditiva. Misturas foram produzidas contendo diferentes quantidades (0 por cento, 5 por cento e 16,7 por cento) e comprimentos (3 mm e 6 mm) de fibras. Cada mistura foi processada através de uma extrusora dupla rosca para a produção de pellets. Os pellets de cada mistura (incluindo pellets de ABS puro) foram analisados para a caracterização do material processado. Posteriormente, corpos de prova foram extrusados para a determinação das propriedades mecânicas e análise da superfície de fratura. As técnicas utilizadas para a caracterização do material foram: espectroscopia no infravermelho (FTIR), análise termogravimétrica (TGA), reometria capilar e microscopia eletrônica de varredura (MEV). Para a avaliação do comportamento mecânico, os corpos de prova extrusados foram ensaiados para a determinação da resistência à tração, módulo de elasticidade e ductilidade. Em seguida, as superfícies de fratura dos corpos de prova foram analisadas no MEV. Foi verificada a possibilidade de degradação da matriz polimérica e formação de vazios durante o processamento inicial do material, que foram eliminados após a segunda extrusão. As fibras de carbono causaram aumento no módulo de elasticidade e diminuição da ductilidade do compósito, apesar de pouco influenciarem as propriedades reológicas. Além disto, pequenas variações na estabilidade térmica foram observadas. Ao final, em anexo, foi elaborado um panorama sobre a Manufatura Aditiva (MA) e a oportunidade de utilização de compósitos em técnicas de impressão 3D.
The goal of this work was to produce, characterize and analyze the mechanical behavior of a carbon fiber reinforced thermoplastic composite with future applications in additive manufacturing. Mixtures were produced with varying carbon fiber content (0 per cent, 5 per cent, and 16,7 per cent) and initial length (3 mm and 6 mm). Each mixture was processed via a twin-screw extruder to produce pellets. Pellets from each mixture (including pure ABS) were analyzed to investigate the processed material properties. Afterwards, test specimens were extruded from each mixture s pellets for mechanical testing and fracture surface analysis. The following techniques were used for material characterization: Fourrier-Transform Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA), capillary rheology and Scanning Electron Microscopy (SEM). For the evaluation of mechanical properties, the extruded test specimens yield strength, Young s modulus and ductility were determined. Also, the fracture surfaces were observed using SEM. The effects of processing parameters and of the introduction of carbon fibers in the ABS polymer were determined. Results pointed out the possibility of degradation during initial processing and the formation of voids in the pellets structure, which were eliminated during the second extrusion. Results also showed an increase in modulus and a decrease in ductility of the composite, whereas rheological properties seemed largely unaffected. Additionally, small variations in thermal stability were observed with varying carbon fiber content and length. Finally, as an annex, a brief overview of Additive Manufacturing and the opportunities for using carbon fiber reinforced thermoplastics in 3D printing techniques is presented.

Texto completoThe first objective is addressed through a computational modeling and simulation of the infiltrating dual-scale resin flow through the micro-architectures of woven fibrous preforms, accounting for the capillary effects within the fiber bundles. An analytical model is developed for the longitudinal permeability of flow through fibrous bundles and applied to simulations which provide detailed predictions of local air entrapment locations as the resin permeates the preform. Generalized design plots are presented for predicting the void content and processing time in terms of the Capillary and Reynolds Numbers governing the molding process.
The second portion of the research investigates the damping enhancement provided to FRC\'s in static and rotational configurations by different types and weight fractions of matrix-embedded carbon nanotubes (CNTs) in high fiber volume fraction composites. The damping is measured using dynamic mechanical analysis (DMA) and modal analysis techniques, and the results show that the addition of CNTs can increase the material damping by up to 130%. Numerical simulations are conducted to explore the CNT vibration damping effects in rotating composite structures, and demonstrate that the vibration settling times and the maximum displacement amplitudes of the different structures may be reduced by up to 72% and 50%, respectively, with the addition of CNTs.

Este trabalho é uma pesquisa experimental realizada no Laboratório de Estruturas e Materiais da PUC–Rio, utilizando–se a técnica de aplicação do compósito de fibras de carbono (CFC) colados externamente em consoles curtos de concreto armado. Foram ensaiados seis consoles curtos, sendo: um de referência, três com reforço de CFC na horizontal e dois com reforço de CFC na diagonal. A resistência média do concreto aos 28 dias foi de 30 MPa. A seção transversal do pilar foi de 25 cm × 50 cm e a seção do transversal console foi de 25 cm × 37,5 cm. O diâmetro da armadura tracionada em laço era de 10 mm e o diâmetro da armadura de costura era de 6,3 mm. Os consoles foram instrumentados com extensômetros elétricos de resistência na armadura tracionada, no estribo, no concreto e no CFC. Os ensaios comprovaram um razoável desempenho dessa técnica de reforço. Os resultados experimentais foram comparados com os resultados obtidos no modelo de Bielas e Tirantes e no modelo cinemático da Teoria da Plasticidade, visando a comparação das forças verticais últimas teóricas e experimentais. Foi avaliado o ângulo de inclinação das bielas e o fator de efetividade da deformação específica no reforço de CFC.
This work is an experimental research of concrete short corbels wrapped with Carbon Fiber Reinforced Polymer (CFRP) strips. Different strengthening configurations were used. Was carried out on six corbels strengthened by CFRP. One control specimen without CFRP, three corbels with horizontal CFRP strips and two corbels with diagonal CFRP strips. The concrete had a 28 day compressive strength of 30 MPa. The column cross-section dimensions were 25 cm x 50 cm and the corbel cross-section dimensions were 25 cm x 37,5 cm. The flexural reinforcement consisted of four deformed bars each of diameter 10 mm with four transverse bars of diameter 6,3 mm. The corbels were instrumented with strain gages in flexural reinforcement, stirrup, concrete surface and CFRP strips. The analytical models based on Strut-and-Tie model and in the kinematic model of the Theory of Plasticity, allows one to determine the bearing capacity of corbels. The experimental values are then compared with the analytical results, showing good agreement. The strut angle and the strengthening effectiveness were evaluated.

The quality of composite parts and structures depends strongly on the friction present during the composite forming process. One of the major challenges in the forming process is the occurrence of wrinkling and shape distortions of the fabric caused by the surface differences between the forming tool and material. The presence of these defects can compromise the final material property and lead to failure when in use. Frictional measurements of composites can vary widely depending on processing parameters, measurement technique, and instruments used. The extent of interaction between the tool and surface of the material depends on the tooling height, and by extension, contact area, which cannot easily be monitored with traditional test designs. A commercial rheometer was used in this study to evaluate tool-ply friction of unidirectional carbon fiber epoxy prepreg at various contact pressures, temperatures, and sliding velocities. Gap height and torque were monitored to provide information on the frictional dependence of processing parameters. In addition, surface-imaging results were coupled with rheological results to examine the relationship between friction and fiber distortions. The understanding of changes in material property with respect to the tooling process is the key to optimizing the composite forming process.
