摘要：

Influence of filler diameter on fatigue resistance of polypropylene (PP)/filler composite was investigated. Several kinds of calcium carbonate having mean diameters from 0.12 to 20 mu m were used as fillers. Fillers were surface-treated with fatty acids in order to prevent the aggregation of filler particles. Tensile yield stress of the composite was lower than that of pure PP. That showed little dependence on the filler diameter. Also, it seemed that there is no interfacial adhesion between PP and filler. The fatigue property of PP/filler composite was lower than that of pure PP. The composites including filler with smaller diameter showed better fatigue resistance than the ones with filler with larger diameter. Especially, the composites including fillers having mean diameters of 0.9 and 0.12 mu m showed remarkably high fatigue resistance.
