Abstract

The present invention involves Bi-axial Bias weaving method for two dimension woven preform having interlaced bias strands. The material includes plain, twill and satin structures made of two bias flat strands (tape) interlacing each other at particular angle (30- 60). The weaving machine includes bias holders assembly, chains, bias rapiers and take-up assembly. Each Bias holder is responsible to hold the flat bias strand and shedding in order to produce the desired structures such as plain, twill and satin. Chain holds the bias holders assembly and rotate in order to make production continuous. Rapier is mean to insert the bias strand into the shed produced by Bias holders assembly. Bias strand feeding set-up is connected with rapier assembly. Two dimension woven preform have been successfully manufactured in most common designs such as Plain, Twill and Satin using high performance fibres (carbon). The embodiment of this invention may be utilized to produce high performance preforms (Kevlar/Glass/Carbon) for aerospace composites.

Keywords: Bias weave, Textile preform, Bias holder
