摘　　要：Benzoxazine resin,being a new type of phenolic resin deve-loped to overcome the shortcomings of traditional phenolic resins,has been synthesized from phenol,formaldehyde and amine,and does not require solvent elimination or monomer purification to obtain a relatively clean precursor.It has potential application in the field of aerospace due to its low expansion coefficient,high weather resistance,high carbon yield,good mechanical strength,and excellent ablation resistance[1].It can be mixed with various other resins or polymers to produce new resins with a broad range of applications[2-3].通过实验和分子模拟研究了苯并吃恶嗪树脂(PBR)对丁腈橡胶(NBR)复合材料力学性能的影响。结果表明,PBR对NBR复合材料具有明显的增强作用,特别是当PBR为20份(质量)时复合材料具有最多的氢键数、最高的结合能和较小的自由体积分数;与纯NBR相比,NBR/PBR 20复合材料的拉伸强度和玻璃化转变温度分别提高了55.6%和5.13℃。
