缝合复合材料泡沫夹层结构侧压剪切力学性能试验研究
Mechanical Behavior Tests of Composites Stitched Sandwich Panels
摘要
Abstract
Experiments on three kinds of composite foam core sandwich structures under edgewise compression and core shear were presented in this paper. Unstitched foam, lock-stitched foam and tufting stitched foam sandwich structures were produced using the same face material in order to study the stitch methods how to influence the mechanical property and failure modes. The experimental results showed the significant increasing in the strength and modulus of edgewise compression and core shear of the stitched foam sandwich structures. Different stitch methods caused different change of the strength and modulus of stitched structures. Tufting stitch had better ability than lock-stitch in the increasing in the shear strength and modulus but had the same ability as the lock-stitch in the edgewise compression. The results could be used in structural design and theoretical analysis.关键词
