**Abstract**
 A mechanism for void formation is suggested, which involves an analysis of the resin flow through woven glass fabrics, at both the macro and micro levels. Both these types of flow arise from the characteristic structure of woven fabrics. In order to investigate the mechanism of void formation in woven fabrics, a new dimensionless number was defined as the ratio of the superficial velocity to the initial spreading rate. The prediction of void formation using this dimensionless number was shown to have a good correlation with the results from a cross sectional observation and void content measurement. It was confirmed that the mechanism suggested in this study is very useful and that the morphological structure of woven fabrics is conductive to void formation. 11 refs.
