StratifiésIndex. décimale : 668.4 Plastiques, vinyles Résumé : The evolution of multi-hull high performance racing yachts is directly linked to the specific strength and stiffness of the materials available. 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

Simulation par ordinateurIndex. décimale : 668.4 Plastiques, vinyles Résumé : The purpose of this paper is to shed light on how and when 3D simulations are preferable over 2D simulations in order to predict the replicated height of nanocavities via plastic injection moulding. Simulations are necessary since not all the cavity is copied depending on geometrical and injection conditions. A 3D simulation is preferable over a 2D simulation in two cases: (i) when the heat transfer through the walls parallel to the simulated domain is not negligible and (ii) when the polymer final shape is relevant. This work explains when 2D simulations like the more commonly found in the literature are not enough to obtain reliable results and how to obtain such results by means of a 3D simulation.

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.

- Examples of 3D textile composites
- Experimental techniques
- Material variability in the yarns
