A contribution on manufacturing process development for composite material forming
TypeArticles dans des revues avec comité de lecture
The author presents an approach to study an innovative manufacturing process developed to produce composite parts with new geometrical possibilities. The aim of this first study is to understand the motions of fibers during the forming of this kind of composite parts and to explore the feasibility of this forming process by an experimental analysis and FEM simulations with Forge3. The reliability of the simulation tool ans its potential, never exploited in this area, will be evaluated.
