采用预浸料模压工艺制备了纳米凹凸棒土 /短碳纤维 /BMI树脂复合材料 .实验并分析了纳米凹凸棒土对复合材料的增强与增韧作用 .当其质量百分比为 5%～ 6%时 ,弯曲强度和冲击强度分别提高了 30 %和 57%
The nano-attapulgite / short carbon fiber / BMI resin composites were prepared by prepreg molding process.The reinforcing and toughening effects of nano-attapulgite on the composites were analyzed and analyzed.When the mass percentages of nano-attapulgite were between 5% and 6% , Flexural strength and impact strength increased by 30% and 57%
