制备了一种可用于树脂传递模塑(RTM)工艺的高性能苯并噁嗪共混树脂体系(BA21).研究了BA21的注射工艺性,确定了其同化程序,并考察了采用RTM工艺制备的BA21基复合材料的基本力学性能.升温及恒温黏度测试结果表明,BA21树脂体系能够用于RTM工艺.依据修正的双阿累尼乌斯方程建立了与实验数据较为吻合的化学流变模型,利用该模型可以选择合适的注射温度.通过不同温度下的恒温DSC测试及修正的Kamal动力学模型计算得到BA21树脂体系的固化反应级数,并确定后固化温度为200℃.采用RTM工艺制得的玻璃纤维/BA21复合材料表现出优异的力学性能,弯曲强度达600 MPa,弯曲模量达30 GPa,冲击强度达210 kJ/m2.
