Abstract:

The effects of fabric micro structural parameters on elastic properties of woven fabric reinforced composites are investigated based on a two dimensional undulation model proposed by the author. The model takes into account the actual fabric structure by considering the fibre undulation along both the warp and weft directions, the gap between adjacent yarns, actual cross sectional geometry of the yarn and possible fabric stacking arrangements of the woven fabric composites. Variations of elastic properties with fabric micro structural Parameters are presented. Parametric studies are performed to examine the effects of various micro structural parameters on the elastic properties of the composites.
