Abstract:

One of the greatest difficulties in developing detailed models of the mechanical response of textile reinforced composites is an accurate model of the reinforcing elements. In the case of elastic property prediction, the variation of fiber position may not have a critical role in performance. However when considering highly localized stressevents,such as those associated with cracks and holes, the exact position of the reinforcement probably dominates the failure mode.

Models have been developed for idealized reinforcements which provide an insight into the local behavior. However, even casual observations of micrographical images reveals that the actual material deviates strongly from the idealized models. In this paper, some of the deviations and causes are presented for triaxially braided and three dimensionally woven textile composites. The necessary modelling steps to accommodate these variations are presented with some examples. Some of the ramifications of not accounting for these discrepencies are also addressed.
