MECHANICAL PERFORMANCE OF STITCHED FOAM CORE SANDWICH COMPOSITES
摘要
Abstract
The stitched foam core sandwich structure preforms were prepared by new type of stitched machine.Then the vacuum infusion molding process (VIMP) was used to fabricate the stitched foam core sandwich composites.Then the influences of fiber panel layers,fiber panel penetrating layers,stitched angles,stitched step length,the numbers of yarns on the bending and the compression performance were carefully studied.The results show that,compared with the unstitched structure,stitching can significantly improve the bending and compression properties of the composites.The bending stiffness of the structure increased by 4.66 times and the breaking load increased by 13.8 times at most.Simultaneously,the compression strength and compression modulus increased by 26.2 times and 15.2 times at most.关键词
