STUDIES ON MECHANICAL AND SHAPE MEMORY PROPERTIES OF VAPOR GROWN CARBON FIBER/SHAPE MEMORY POLYURETHANE COMPOISTE FILMS
气相生长碳纤维/形状记忆聚氨酯复合薄膜的力学及形状记忆性能研究

In order to improve the mechanical properties of SMPU,vapor grown carbon fiber(VGCF) reinforced SMPU composite films with various VGCF contents were prepared via a solution mixing method.The mechanical and shape memory properties of the pure SMPU and VGCF/SMPU composite films were studied.The results show that,the VGCF still shows good dispersion in SMPU when the VGCF content reaches 9 wt% in the prepared composite film.The tensile strength and stiffness of the prepared composite films are greatly improved ...
