摘要
以苯乙炔封端聚酰亚胺树脂为基体,采用高温RTM工艺复合成型了T300碳布增强聚酰亚胺层合板,复合材料的Tg达351℃(DMA),材料在300℃弯曲强度保持率达90%以上,模量保持率达85%以上,层间剪切强度保持率达60%以上。
High quality carbon/polyimide laminate was fabricated by high temperature RTM by using T300 carbon fabric and phenylethynyl terminated imides resin. The glass transition temperature of the polyimide composite is 351℃. The composite exhibited high retention of mechanical properties up to 300℃：the flexural strength and flexural modulus are maintain at 93.7% and 86. 1% of room temperature properties respectively. The short beam shear strength is maintains at 64% of room temperature property.
