Abstract

Realistic finite element models of 3D woven composites are constructed utilizing micro-scale numerical modeling to accurately represent the geometry of as-woven textile fabrics. The models are used to predict microcracking of carbon fiber / epoxy composites during resin curing. Numerical predictions of the stress concentration areas correlate well with the observations of microcracking obtained by micro-computed tomography.
