A Simplified Discrete Finite Element Model for Non-crimp Fabric Composites

Abstract

In this paper a simplified discrete finite element model for composite materials is introduced. This model allows the discrete representation of both the fibre tows and the resin on a meso-scale level. The capability to assign different material properties to each fibre tow and resin zones allows the investigation of local reinforcements in composites. This modelling concept is combined with a three dimensional damage model and is successfully implemented in a finite element code. Results indicate that relatively fast model analysis and successful approximation of fibre and resin failure under specific load cases may be investigated.
