When mass fraction of Mica was less than5%, the breaking elongation of the composites raised while impact strength decreased evidently with increase of mass fraction of Mica, and then both of them reduced when mass fraction of Mica was more than5%.

• 当云母质量分数小于5%25,复合材料的断裂伸长率随着云母用量的增加而增大,而冲击强度则明显下降;当云母质量分数大于5%25,两者均随着云母用量的增加而减小。
