| 摘 要： | 本文报导一种工艺性能较好的耐高温双马来酰亚胺(BMI)树脂体系。它由二种BMI的共混物与二乙烯苯预聚而成。这种树脂具有低的熔点(63～67℃),良好的溶液性,可用丙酮作溶剂制造预浸料。复合材料的成型温度为180℃,可用普通热压罐成型。成型的复合材料试件经230℃后处理具有高的耐热性:在250℃的强度保持率>60%。

| Abstract: | A new high temperature bismaleimide resin system with improved processability are prepared,which consists of a hot melting mixture of two bismaleimides and divinylbenzene.One of two bismaleimides is 4,4'-bisma leidodiphenylmethane,a comercial product, and another is a substituted bismaleimide which was synthesised by ourselves.This new bismalcimide resin system has a low melting point (about 60℃),better solubility (soluble in aceton,solution can be used in making prepreg), and low curing temperature(180℃).Composite fabricated from this resin exhibits high thermal stability,and its strength retentivity at 250℃ is more than 60%. |
