【摘要】 本文报道用改性物Ｂ改善双马来酰亚胺／二胺预聚物溶解性的实验研究。结果表明，改性后的双马来酰亚胺／二胺基体树脂在低沸点、低毒性溶剂如丙酮中具有良好的溶解性，并且有足够的均相期，为湿法制作预浸料创造了有利条件。同时对树脂的固化反应、耐热稳定性及其复合材料在高温条件下（１５０℃、２００℃）的层间剪切性能进行了研究。更多还原

【Abstract】 The experiment of using modifier B to improve the dissolvability of the prepolymer of bismaleimide/diamine is reported. The prepolymer can be dissolved in acetone easily and the solution has enough long harmonious stage at room temperature. It makes convenient for preparing prepreg. Meanwhile, the properties of resins have been studied by DSC and TG analysis method and the composite’s performance is characterized by interlaminar shear strength (ILSS) at room temperature, 150℃ and 200℃.更多还原
