纤维金属层板的拉伸性能研究

摘要：GLARE是一种先进的混杂层板材料,由髙韧度薄铝合金层和髙强度玻璃纤维/环氧树脂层交替铺设而成,具有独特的轻质、耐疲劳、耐冲击、髙阻燃性和耐腐蚀属性.系统地对GLARE层板进行了静力拉伸测试,展示了铺层结构和铺层类型对其静力学性能的影响,并对混杂模型的适用性进行了验证.结果显示：采用混杂模型法预测GLARE层的轴向弹性模量具有较髙的精度,但进行强度预测时对于部分类型的层板需要考虑纤维的桥接作用....

GLARE laminates are an advanced hybrid material system consisting o f alternating layers of thin aluminium sheets and high strength glass fiber/epoxy composite layers. The unique combination of ductile aluminium layers with high strength composite layers results in a unique fiber-metal laminates （FMLs） with light weight, outstanding fatigue resistance, excellent impact resistance, flame resistance and corrosion properties. Mechanical tests were carried out on many kinds of GLARE laminates, and the influence of ply type on its static behavior has been studied. The mechanical properties o f GLARE laminates were predicted using the metal volume fraction approach based on a rule o f mixtures. The results show that good agreement is obtained between the model predictions and experimental
