1、前言 玻璃钢层合材料的强度各向异性较严重,其压缩和剪切强度比纤维方向的面内拉伸强度小,特别是层间粘接强度(层间剪切、层间分层)最小。作者很明确的认定,玻璃钢层合材的破坏,是层合材特有的层间分层,特别是在冲击载荷作用下,层间分层的倾向更显著。 由于此种原因,而研究开发了几种新的冲 1. INTRODUCTION The strength anisotropy of FRP laminates is more serious, the compressive and shear strength is smaller than the in-plane tensile strength of fiber direction, especially the bonding strength between layers (interlaminar shear, interlaminar stratification) Min. The authors have made it clear that the failure of FRP laminates is a layer-by-layer delamination that is unique to laminates, especially under the impact load. Because of this reason, and research and development of several new Chong
