摘要
研究了陶瓷粉末与ＰＰ混合材料的流变性能，结果发现，随着陶瓷粉末含量的增加，混合材料熔体表现出较高的剪切应力，其表观粘度也相应增加。初生纤维截面形态结构由致密向疏松结构变化。物料混合不匀，在其降温曲线上容易产生双结晶峰。
The rheological behavior of powdered ceramic and PP mixed material was studied. The results show that the shearing stress of the composite rises with increasing of powdered ceramic and so does the apparent viscosity. The morphology of the as mod fibre from compact be comes loose. The composite doesn′t uniform, on its curves of drop in temperature two crystalline peak was appeared.
