Advantages of the Meso/Macro Approach for the Simulation of Fibre Composite Reinforcements
Source abstract
Abstract
This paper presents a new discrete modelling for the dry woven composite reinforcements forming in LCM (Liquid Composite Moulding) processes. Two existing approaches to model woven composite reinforcements at the macroscopic and mesoscopic scale are reminded and our modelling at the mesoscopic scale which can be applied to large fabric pieces is presented. The mechanical behaviour of each compound in such a model is simpler than for continuous models and difficult aspects such as yarn's direction updating are naturally built in as in the mesoscopic approach. The compensation lies in the large amount of components with complex contacts between them. Interests of this approach such as the prediction of the apparition of wrinkles and “unweaving” phenomena are also detailed and illustrated by the simulation of a picture frame test and of a deep drawing forming.
