摘　　要：摩阻材料的裂纹扩展以Z字形前进,在一定范围内具有自相似性;试样断口LogP￣LogA关系点图及其回归效果显著,纤维增强摩阻材料断口具有分形特征,断口形貌可用分形维数来表征;分维值的变化与抗冲击强度的变化一致,分形维数随抗冲击强度的增大而增大。Frictional materials＇s spreading crack advanced as Z shape and was self-similarity in certain extent; scarer and regression was obvious; fiber reinforced frictional materials had fractal character; fracture pattern can be characterized by fractal dimension; variation of fractal dimension was consistent with resistance to impact, fractal dimension increased with more resistance to impact.
