Experimental and numerical analysis of wrinkling during forming of multi-layered textile composites

Wrinkling is one of the main flaws that can appear during forming processes of textile composite reinforcements. When the forming is carried out on a multi-layered fabric the wrinkle development is strongly increased if the plies have different orientations. This phenomenon has been observed in previous experimental studies and is confirmed by a set of forming tests on multi-layered reinforcements. Beyond these experiments, a multilayered fabric...
