| 摘 要： | 研究了刚性聚醚酰亚胺(PEI)改性双马来酰亚胺(BMI)树脂体系粘度特性和凝胶特性,以及PEI/BMI/RS/玻纤复合材料的力学性能。研究结果表明:PEI的加入使树脂体系的凝胶时间延长,导致树脂熔液在低粘度时的温度范围缩小和粘度增大。在PEI含量5%左右时,复合材料的综合力学性能较佳,弯曲强度提高了28.0%,冲击强度提高了26.1%。

| Abstract: | The viscosity and gel time of resin system of modified bismaleimide(BMI) resin with rigid polyetherimide(PEI) and the mechanical properties of PEI/BMI/RS/ glass composite materials were studied.The results show that the addition of PET resin extends gel time,narrows temperature range at low viscosity of the melt resin system.PEI 5% in the content,the composite material has better mechanical properties,bending strength increase by 28.0%,impact strength 26.1%. |
