5231树脂体系/碳纤维复合材料力学性能研究

着重研究了5231／T300复合材料的常规力学性能和高温下的力学性能，并与5222／T300复合材料的相应性能进行了对比，试验表明，前者在抗压缩模量和抗剪切性能方面比后者略低，其他力学性能基本相当，耐高温性能良好，另外，5231碳布预浸料可与铝蜂窝直接共固化，抗滚筒剥离强度较高，该复合材料可应用于飞机的结构件上。

Study on the Mechanical Properties of Carbon Fiber Composite with the Matrix of 5231

The mechanical properties of 5231/T300 composite at room temperature and high temperature,which are compared with those of 5222/T300 composite are typically studied in this paper.The tests shows that the compressive modulus and shear properties of the former one are a little lower than those of the latter one,the other properties of them is basically matched,the properties at high-temperature for 5231/T300 composite are good.In addition,the 5231/G803 carbon cloth prepreg can be co-cured directly with aluminum honeycomb.The climbing drum peel strength of the sandwich structure is high.In one word,the 5231/carbon fiber composite can be applied in the structural parts of aircrafts.
