摘　　要：选择偶氮二甲酰胺作为发泡剂,研究结果表明:在复合材料中发泡剂对其质量影响最大,随着发泡剂用量的增加,所得材料的密度、硬度及拉伸强度呈下降趋势,而断裂伸长率则逐步上升。Azobisformamide was chosen as blowing agent. The results showed that blowing agent has great influence on foaming quality. With the increase of the amount of blowing agent, the density; the hardness and the tensile strengths of the composite decreases, but the elongation at break increases.
