The capability of the material to resis delamination cracks is one of the key problems to solve. This paper shows how the detaminat on resistance depends on the properties of the base materials (fibres and resin) and present a new technology aimed at increasing the crack propagation resistance: Z-Fiber pinning.

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

Structures tridimensionnellesIndex. décimale : 668.4 Plastiques, vinyles Résumé : Designing structural parts made of 3D textile-reinforced materials demands a deep understanding of the different physical phenomena to be accounted for at the individual steps from manufacturing to exploitation. The process relies on numerical methods to resolve multi-scale material modelling and includes the quantification of various manufacturing effects using advanced experimental techniques.

Renforts textilesIndex. décimale : 668.4 Plastiques, vinyles Résumé : Continuous fiber reinforced plastics with a thermoplastic matrix are recyclable, weldable and suitable for many structural applications. Due to the short cycle times of about 1 minute, forming processes for thermoplastic composite parts are already capable of series productions.
Two of the most important forming technique are matched die forming and diaphragm forming. The matched die forming provides short cycle times and high processing temperatures but requires complex and expensive molds. The diaphragm forming process enables the use of low cost tooling and machinery and provides a high degree of flexibility. On the other hand its processing temperature range is limited to 250°C due to the silicone diaphragms, which are used for cost-efficient series production. The paper presents a new processing technique that was developed at IKV Aachen and combines the advantages of both processes. These particularly are a big variety of processable matrices and low cost equipment with a high degree of flexibility. The developed machinery like the new handling system, the innovative IR-heating station and the modified forming technique are described in detail. The development focuses on a temporal reduction of the thermal load of the diaphragms by using them only for the forming process. As a result, the processing temperature range has been extended from 250°C to 320°C so that it is now possible to additionally process PA6, PA66 and PPS based prepregs.Note de contenu : - Project goals
