Abstract
Abstract Multilayer, integrally woven preforms have been constructed from E-glass yarn in three different weave architectures with the in-plane fibres exhibiting minimum crimping. Microscopic examination of the architectures after resin transfer moulding revealed that the binder yarn arrangement and compaction pressure have a strong influence on the distribution of fibres and resin-rich areas. However, preliminary mechanical testing indictated that, for the preforms investigated, the final weave architecture does not have a significant influence on the tensile mechanical performance of the composite structure. A procedure is described for producing a geometric model of the architecture of such multilayer woven preforms which may then be used for their visualisation and to quantify geometric characteristics for use in further analysis.
