| 摘 要： | 本文采用粘贴片式双悬臂梁(DCB)试件和端部切口弯曲(ENF)试件研究了平纹织物的经纬纱密度对玻璃平纹织物/环氧树脂复合材料的Ⅰ型和Ⅱ型层间断裂韧性的影响。实验结果表明织物的密度对层间断裂韧性有显著的影响。提出了在织物增强复合材料层合板中,基体在织物孔洞中形成层间铆接,并且就其与层间GIC和GIC的关系进行了研究。

| Abstract: | The effect of warp and pick densities of plain fabrics to interlaminar fracture toughness (Mode Ⅰ and Mode Ⅱ)of glass-fiber plain fabric/epoxy was studied by double cantilever beam (DCB) and end notch flexure (ENF) tests. It is found that the densities of fabric will influeuce the delamination fracture toughness evidently. The problem of interlayer matrix rivetting in woven-reinforced composite materials was proposed. Moreover,the relation between rivetting and GIC and GIC values was researched. |
