摘要: 对比研究了芳纶Ⅲ纤维复合材料、芳纶Ⅲ纤维/T800碳纤维混杂复合材料、T800碳纤维复合材料单向板压缩性能,以及三种状态下缠绕的ø150 mm容器轴压性能。结果表明:混杂复合材料压缩强度和模量随混杂比(VCF)的增大而增加,当VCF为28.5%时,混杂复合材料单向板压缩强度比芳纶Ⅲ纤维复合材料提高57%,压缩模量提高20.9%;混杂复合材料ø150 mm容器(VCF=46%)轴压破坏载荷达到138.6 kN,比芳纶Ⅲ纤维复合材料ø150 mm容器的轴压破坏载荷提高18.5%,但仍为混杂负效应。

Abstract: Compression properties of aramid Ⅲ fiber composite, carbon/aramid Ⅲ fiber composite and carbon fiber(CF) composite were studied. The axial compression of ?150 mm shells in these consituations were also tested. The result shows that compression strength and modulus of hybridcomposites are improved with the increase of the CF volume (VCF). The compression strength and modulus of hybid composite improve in respective by 57% and 20.9% when the relative volume of CF is 28.5%. Compared with the axial compression of aramid Ⅲ fiber shells, the axial compression of 150 mm shells (VCF=46%) reaches up to 138.6 kN and improves by 18.5%. Nonetheless, it still shows minus effect.
