| Résumé : |
The traditional use of composites for laminates and components is based on unidirectional tape stacking. Generating an allowable design has become a huge undertaking ; several knockdown factors such as barely visible impact damage (BVID), moisture absorption and de-lamination are also involved. In spite of all these negative aspects, composites have begun to be widely used (more than 50% of Boeing 787 and Airbus 350 structures) due to notable design and manufacturing improvements in recent years. The introduction of bi-angle non-crimp fabric composites, pioneered by Stephen W. Tsai (Stanford University) and Michel Cognet (Chomarat), may represent a breakthrough, and a radical change in the way composite structures can be designed and manufactured. Different case studies are presented in this paper with the aim of showing how scaling can help simplify and enhance the way composite structures can be designed and how C-Ply NCF can replace existing composite structures. |
