摘　　要：以双马来酰亚胺树脂(BMI)为基相,碳纤维为增强型,氢化羧基丁腈橡胶(HXNBR)为粘弹性材料。用分子动力学模拟揭示180℃下HXNBR与BMI共固化机理,根据正交试验法通过改变硅烷偶联剂KH550和加工助剂WB212的含量,设计出性能优良的BMI基嵌入式共固化阻尼复合材料(ECCDS)。通过硫化性能进行测试,表明KH550和WB212的加入增大了阻尼材料的交联度和硫化特性。对其进行红外光谱和微观形貌分析,验证了HXNBR与BMI之间确实有大量新的新化学官能团产生,并形成了互穿网格结构,使复合材料的层间结合性能显著提高。The bismaleimide resin(BMI)was used as the base phase,carbon fiber as the reinforcement,and hydrogenated carboxyl nitrile butadiene rubber(HXNBR)as the viscoelastic material.Molecular dynamics simulation was used to reveal the co-curing mechanism of HXNBR and BMI at 180℃.By changing the content of silane coupling agent KH550 and processing assistant WB212,a BMI embedded co-curing damping composite(ECCDS)with excellent properties was designed.The vulcanization test result indicated that the addition of KH550 and WB212 increased the degree of crosslinking and vulcanization property of the damping material.The infrared spectrograph and micromorphology analysis confirmed that a large number of new chemical functional groups were generated between HXNBR and BMI,and an interpenetrating mesh structure was formed,which significantly improved the interlayer bonding properties of the composite material.
