VARTM工艺用乙烯基酯树脂基体配方及性能研究

摘要

以溴化改性乙烯基酯树脂、氨基甲酸酯改性乙烯基酯树脂为混合基体,以E-玻璃纤维(GF)为增强材料,通过真空辅助树脂传递模塑(VARTM)工艺制备乙烯基酯树脂/GF复合材料,对其力学性能和阻燃性能进行了研究.结果表明,在两种树脂质量比为1:1时该复合材料的拉伸强度与弯曲强度达到最大值,且综合性能最优.氧指数随溴化改性乙烯基酯树脂含量的增加而增加.%Based on the duplex matrix of bromized vinyl ester resin and carbamic vinyl ester resin, reinforced by E - glass fiber( GF), vinyl ester resin/GF composites were prepared with VARTM. Mechanical properties and flame retardancy of vinyl ester resin/GF composites were studied. The result showed that the tensile strength and fiexural strength of the composite achieved the maximum and had the best multipurpose properties when the weight ratio of the two resins was 1:1, and the oxygen index increased as the increasing of bromized vinyl ester resin content.
