摘　　要：为了满足结构设计要求,在增强材料相同的情况下考核高温1号、中温1号和中温2号碳纤维复合材料的静态力学性能技术指标。从宏观力学的角度,对三种基体材料不同铺层方式的复合材料层压板进行的开孔拉伸静态力学性能试验结果进行分析。结果表明中温2号样品的极限开孔拉伸强度、极限拉伸、应变弹性模量优于高温1号和中温1号样品,接近国外同类型产品。中温2号样品的极限开孔拉伸强度、极限拉伸和应变弹性模量分别为389 MPa,6420με和42.6 Gpa。In order to meet the requirements of the designed structure,the static mechanical properties of high temperature sample 1,medium temperature samples 1 and 2 of carbon fiber-reinforced composites were tested.The static open-hole tensile strength tests were conducted on the composite boards laminated with the above-mentioned three matrix samples in different manners.Results show that the ultimate open-hole tensile strength,ultimate tensile strength and elastic modulus of medium temperature sample 2 were 389 MPa,6420 με and 42.6 GPa,respectively,better than those of high temperature sample 1 and medium temperature sample 1,while approximate to those of the same products from abroad.
