摘　　要：采用二烯丙基双酚A(O-DABPA)对双马来酰亚胺(BMI)树脂进行改性,利用两步热熔预浸法对改性双马来酰亚胺树脂制备国产T800/双马来酰亚胺树脂预浸料,通过对复合材料单向板进行力学性能测试,研究其常温和240℃时力学性能。结果表明,改性BMI树脂制备的预浸料工艺性良好,常温下0°单向板拉伸强度为2479.13Mpa,240℃时拉伸强度为1567.70 Mpa,强度保留率为63.24%。Domestic-made T800/Bismaleamide Resin prepreg is prepared by the two-step hot melting process with bismaleamide(BMI)resin modified by Diallylbisphenol A(O-DABPA).The mechanical properties of monolithic laminates produced with this prepreg are studied under both normal temperature and 240℃via mechanical property tests.Good processing properties of prepreg prepared from modified BMI resin are indicated by the study results:for 0°monolithic laminate,the tensile strength is 2479.13 Mpa and 1567.70 Mpa respectively under normal temperature and 240℃,and the strength retention rate is 63.24%.
