摘　　要：基于压拉平衡为特征的新一代先进复合材料的需求,开展了碳纤维截面形状和尺寸对碳纤维/环氧树脂复合材料压缩强度的影响研究。有限元模拟和试验结果均表明,增大碳纤维直径可以提高复合材料压缩强度。另外碳纤维截面形状也对复合材料压缩强度有影响,圆形截面优于椭圆形截面。Based on the demand of new generation advanced composites characterized by the balance of compressive and tensile strength, the compressive strength of carbon fiber/epoxy composites with various cross section characteristics of carbon fibers was studied by finite element simulation and experiment. Results show that the compressive strength of carbon fiber/epoxy composite increases with the increasing fiber diameter, and round is better than ellipse regarding to the fiber cross section shape.
