摘　　要：以聚丙烯(PP)为基体、碳纤维(CF)为增强材料、空心玻璃微珠(HGB)为增韧剂制备了CF/HGB/PP三元复合体系,研究了CF、HGB含量对复合体系力学性能的影响,并对复合体系的微观结构进行了分析。结果表明:当CF含量为5份、HGB含量为15份时,CF/HGB/PP三元复合体系的综合力学性能最佳,其拉伸强度和缺口冲击强度分别比纯PP提高了46.5%和17.6%。The cellulose nanofibrils（CNFs）/polyvinyl alcohol（PVA） composite was prepared by solution casting.The effect of CNFs on thermal and mechanical properties of the composite were investigated by TG,DSC and DMA.The results show that the addition of CNFs increases the crystallinity and melting point of PVA,while with increase of CNFs content,the crystallinity and melting point of PVA decrease because of the hydrogen bond between CNFs and PVA,which limits the movement of PVA molecular chain;the addition of CNFs increases the glass transition temperature,tensile strength and elastic modulus of PVA,both tensile strength and elastic modulus of 2%/CNFs composite are up to the maximum values,which increase by 28.98% and 14.1% respectively than those of pure PVA.
