以4，4 '-双马来酰亚胺二苯甲烷（BDM）、双酚A（DBA）和[（6-氧代-6H-二苯并[c，e] [1，2]氧磷杂环-6-基）甲基]丁二酸（DDP）为阻燃树脂体系（BDDP），制备了阻燃性能显著提高、机械强度和介电损耗较低的新型玻璃纤维（GF）/双马来酰亚胺复合材料。研究了DDP在基体中的含量对复合材料综合性能的影响。结果表明，GF/BDDP复合材料不仅力学性能和介电性能得到显著提高，而且具有优异的阻燃性能。GF/BDDP复合材料的阻燃机理主要是凝聚相机理。DDP的引入显著增强了GF与树脂基体之间的界面结合力，这是GF/BDDP复合材料优异性能的原因。(C)2014爱思唯尔有限公司版权所有。
Novel glass fiber (GF)/bismaleimide composites with significantly improved flame retardancy, higher mechanical strength and lower dielectric loss were developed, of which the resin matrix is a new flame retarding resin system (BDDP) based on 4,4'-bismaleimidodiphenyl methane (BDM), bisphenol A (DBA) and [(6-oxido-6H-dibenz [c,e] [1,2] oxaphosphorin-6-yl)-methyl]-butanedioic acid (DDP). The influence of the loading of DDP in the matrix on the integrated performances of composites was intensively studied. Results show that GF/BDDP composites not only have significantly improved mechanical and dielectric properties, but also possess excellent flame retardancy. The main flame retarding mechanism of GF/BDDP composites is the condensed phase mechanism. The introduction of DDP significantly strengthens the interfacial adhesion between GF and the resin matrix, this is responsible for the attractive performances of GF/BDDP composites.
