| 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. |
