摘　　要：通过压缩试验,研究了不同纤维体积含量的碳纤维3层连接纬编双轴向多层衬纱织物增强复合材料的压缩性能;并对压缩试件的破坏断口进行了VHX-1000超景深三维显微镜分析,以认识其压缩失效机理。试验结果表明:在试验研究的碳纤维体积含量范围内,纬编双轴向衬纱织物增强复合材料的压缩强度和压缩模量随纤维体积含量的增大而增大。纤维体积含量的变化未导致压缩破坏机理的变化,材料表现为脆性特征。The compression properties of threelayer biaxial weft knitted carbon fiber fabric reinforced compos ites for carbon fiber with different fiber volume fraction of specimens were investigated by the compressive experi ments. In order to understand the compressive failure mechanism of this kind of composite, the VHXIO00 16bit Resolution Microscope analysis was performed for the fracture surface of specimens. The results show that the com pression strength and compression modulus increase with the increase of fiber volume fraction of specimens. The compressive failure mechanism of the composites will not change with the increasing of fiber volume fraction of specimens. And the material failure behaves the brittle characteristics.
