Abstract
Abstract In this study formability of three different Multilayer E-Glass 3D orthogonal woven preforms with varying stuffer (warp yarns) and binder (through thickness yarn) ratio is experimentaly investigated. 3D orthogonal woven reinforcements were developed using a in house fabricated mutibeam rigidrappier weaving machine. Formability behaviour of all structures were analysed using a fabricated formability fixure, with hemispherical pluger. Stuffer and binder yarn percenatge by mass were varied keeping same fiber volume fraction in all three structure, It is obsrved that binder percetage, Number of crossover point in a unit cell, singnificantly influence formability behaviour of the strucures.
