Abstract :The present work concentrates on the development of 3-D hemispherical biaxial weft-knitted insert ignore into journalissuearticles values(BWK); thermoset composites. The objective is to improve the quality of the 3-D composites with BWK preform. Two kinds of the 3-D hemispherical BWK composites with the flat surfaced and 3-D dome shaped biaxial weft-knitted preforms were produced by hand lay-up method. The quantitative analysis of wrinkles was done by measuring the locking angles between the fiber bundles in the composites. Small numbers of wrinkle heights insert ignore into journalissuearticles values(1 height/1 cm); were observed on the flange surface of the 3-D hemispherical BWK composite with the dome shaped preform compared to the 3-D hemispherical BWK composite with the flat surfaced preform insert ignore into journalissuearticles values(10 heights/1 cm);.Keywords : biaxial weft knitting, 3 D thermoset composites, locking angle, wrinkle of surface
