冷間圧延したPP/LCPブレンドの内部構造と引張特性

抄録

The relation of the microstructure, the dynamic viscoelasticity, the molecule orientation and the micro hardness of the PP/LCP blends to the tensile property have been examined by rolling tests. The result shows that : (1) With the increase in the rolling ratio, (1) the LCP phase of reinforcement is delayed and the distribution is improved. (2) The specimens is softened as the E' and the section hardness decrease. (3) The distribution of hardness and the molecule orientation in all specimen sections become more uniform. (2) The rolling process has improved the material property of brittle blends and their ductile property rises drastically. Especially, under the high rolling ratios such as 60% the strength and the stretch of the material have been improves greatly. (3) Thus, it is considered that the rolling processing may be an effective way to improve the microstructure, phases interface bond strength and ductile property of composite material.
