摘　　要：为研究纤维增强树脂基复合材料厚度方向拉伸性能,设计碳纤维增强树脂基复合材料/玻璃纤维增强树脂基复合材料(CFRP/GFRP)层合板厚度方向直接拉伸试样形状尺寸、金属加载杆粘接方法、试验参数,判断拉伸试样失效模式。结果表明:测得的复合材料拉伸强度(σ33)、拉伸模量(E_(33))、31方向泊松比(ν31)、32方向泊松比(ν31)、拉伸断裂应变(με)试验结果重复性良好,试验方法可行,并参加国际循环比对试验,验证方法的实验室间再现性,给出方法的精密度数据。In order to study the mechanical properties of the composite material in the thickness direction,the shape and size of direct tensile specimens in CFRP and GFRP unidirectional laminate thickness direction,the bonding method of metal loading rod,and test condition parameters were designed.The failure mode of tensile specimens was judged.The results shown that the tensile strength(σ_(33)),tensile modulus(E_(33)),31-direction Poisson's ratio(ν_(31)),32-direction Poisson's ratio(ν_(32)),tensile breaking strain(με)of the specimens had good repeatability.The test method was feasible,and participated in the international circular comparison test to verify the reproducibility of the method between laboratories,and given the precision data of the method.
