摘要

采用碳纤维(CF)与高密度聚乙烯(HDPE)制备了HDPE/CF复合材料,并研究CF掺量对复合材料力学性能和耐久性能的影响.结果表明:随着CF掺量的增加,复合材料的力学性能和耐久性能均得到增强.当CF掺量为12%时,复合材料的拉伸强度比纯HDPE提高145.9%,弯曲强度比纯HDPE提高220.4%,冲击强度比纯HDPE降低5.9%.当CF掺量为12%时,复合材料的维卡软化温度(VST)最高,比纯HDPE提高19℃.掺入12%的CF,能保证复合材料有较高力学性能和最佳的耐久性能.

Abstract

HDPE/CF composites were prepared by using carbon fiber(CF)and high density polyethylene(HDPE),and the effects of CF content on the mechanical properties and durability of the composites were studied.The results show that the mechanical properties and durability of the composites are enhanced with the increase of CF content.When the content of CF is 12%,the tensile strength and flexural strength of the composite are 145.9%and 220.4%higher than that of pure HDPE,the impact strength is 5.9%lower than that of pure HDPE.When the content of CF is 12%,the Vicat softening temperature(VST)of the composite is the highest,which is 19℃higher than that of pure HDPE.Adding 12%CF can ensure that the composite has higher mechanical properties and the best durability.
