聚芳醚砜醚酮酮及其炭纤维复合材料的力学性能

Mechanical Properties of Poly(Aryl Ether Sulfone Ether Ketone Ketone)/Carbon Fibers Composites

合成了聚醚砜醚酮酮(PESEKK),研究了纯树脂的热、力学性能。制备了炭纤维和聚醚砜醚酮酮(炭纤维是标准T300)复合材料,着重研究了此新型复合材料的力学性能。结果表明,随着复合材料中PESEKK树脂质量比增加,T300CF/PESEKK复合材料的拉伸强度、弯曲强度、拉伸模量和弯曲模量逐渐增加。其中弯曲强度和弯曲模量增加的幅度比拉伸强度和拉伸模量增加的幅度更大。当PESEKK质量分数为60%左右时,复合材料的综合力学性能达到最佳值。因此聚醚砜醚酮酮可作为增强炭纤维力学性能的基体树脂。

The mechanical properties of hybrid composites from carbon fibres and poly（aryl ether sulfone ether ketone ketone）（PESEKK） have been evaluated over a range of PESEKK： carbon fibres ratios.Comparing to pure PESEKK,the carbon fibres /PESEKK composites show a great mechanical performance.With increase the ratios of carbon fibres /PESEKK,the mechanical properties of composites enhance.When PESEKK is 60%,composites show the best mechanical properties.The reason could be the polar sulfuryl in PESEKK can strongly bond to the polar carbon fibres surface.PESEKK can be used as a good resin matrix and it can compound with CF to enhance the mechanical properties of T300 CF/PESEKK composites.
