Traction (mécanique)Index. décimale : 668.4 Plastiques, vinyles Résumé : Fibre-reinforced plastics (FRP) in the form of continious fibre-reinforced thermoplastics composites exhibit a great potential for mass production of complex, load-bearing and recyclable components in automotive and mechanical engineering.
The use of thermoplastics matrix materials makes it possible to manufacture lightweight, high-quality complex-shape composites cost-efficiently and with high productivity. To ensure the demanded short cycle times while simultaneously guaranteeing highly specific properties of structural components, the most suitable method is hot pressing, using deep drapable multilayers and 3D-shaped thermoplastic preforms based on thermoplastic hybrid yarns. The advantages of glass fibre/PP hybrid yarns are their homogenous combination of continuous filaments, as well as their great yarn compaction, which permits further textile technological processing. Commercially available yarn materials can be used in widely varying forms, and the individual intra-yarn content percentages can be ajusted to preference oven an exrensive range. 3D-shaped multilayer woven fabrics are suited for the reinforcement od higher-gauge FRP due to the use of thicker and preferably compact fabrics, as their multilayers structure helps minimase the usual stacking of multiple individual reinforcement layers. In this study, hybrid yarns and composite sheets made of multilayers woven fabtics are tested according to their mechanical properties.Note de contenu : - EXPERIMENTAL : Hybrid yarn manufacturing - Weaving technology for 3D-multilayer woven spacer fabric - Thermoforming process

PolyamidesUn polyamide est un polymère contenant des fonctions amides -C(=O)-NH- résultant d'une réaction de polycondensation entre les fonctions acide carboxylique et amine.
Selon la composition de leur chaîne squelettique, les polyamides sont classés en aliphatiques, semi-aromatiques et aromatiques. Selon le type d'unités répétitives, les polyamides peuvent être des homopolymères ou des copolymères.

TissésIndex. décimale : 668.4 Plastiques, vinyles Résumé : The current work aimed at investigating experimentally the weave pattern effects on the mechanical and dynamic behaviors of polymer matrix composite laminates. The laminates composed of three different weave types (plain, satin, and twill) of woven glass fabric and STR Medapoxy epoxy resin were fabricated via vacuum molding. Static bending experiments were applied to determine the influence of the weave pattern on the mechanical characteristics of the samples. The failure behaviors of the samples were also examined by optical and Scanning Electron Microscopy (SEM) analyses. Additionally, Dynamic Mechanical Analysis (DMA) in the temperature range of 25–200 °C at 1 Hz frequency was conducted to investigate the dynamic characteristics of the samples. It was found that the samples having satin weave type had the best flexural modulus followed by the plain and twill weaves. However, the twill weave laminates exhibited better storage modulus at glass transition temperature values (T g) compared to the others. Also, an increase of 3.3 °C in glass transition temperature was observed compared to that of neat resin. This was attributed to the better fiber/matrix adhesion and the lower molecular mobility in the polymer chain by the addition of glass twill fibers.

StratifiésIndex. décimale : 668.4 Plastiques, vinyles Résumé : Due to their qualities and advantages, such as light weight, high rigidity, and high performance, composite materials have been used in a wide variety of industries and sectors. For example, carbon fibres are used in the construction of aircraft, while ultrahigh-molecular-weight polyethylene (UHMWPE) is used in the fabrication of medical artificial joints. In this study, the blade dimensions were estimated using side profiles from a European patent specification and the mechanical properties of numerous layers of composite materials (UHMWPE, carbon, glass fibre, and Perlon) utilized in the fabrication of sports prosthesis were investigated experimentally, theoretically, and numerically, and the results were compared, as well as the theory of failure calculated. The influence of data entered into the ANSYS programme was also investigated in the case of isotropic or orthotropic materials. The findings indicate that longitudinal young modules are experimentally and theoretically equivalent. While the material ISO or Ortho is considered and its information is entered into the ANSYS programme for the same lamina, similar results are obtained under the same boundary condition, as was demonstrated when computing the theory of failure. Additionally, it was demonstrated in this research that layering woven carbon fibre on top of layers of UHMWPE woven fabrics had a greater effect than layering woven glass fibre when fabricating the sports prosthetic foot.
