摘要
以碳纤维(CF)为增强体,以聚对苯二甲酸丁二醇酯(PBT)/氢化聚苯乙烯-丁二烯-苯乙烯三嵌段共聚物(SEBS)为复合基体,制备了一系列不同CF质量分数的PBT/SEBS/CF复合材料.研究了CF质量分数对复合材料体系力学、热学以及加工性能的影响.结果表明:CF可以均匀地分散在PBT/SEBS复合基体中,而没有团聚现象发生;随着CF质量分数的提高,复合体系的熔体黏度、储能模量、拉伸强度与模量、弯曲强度与模量、热稳定性均有不同程度的提高,而冲击强度则有一定程度的下降.
Mechanical,thermal properties and processability were performed on a series of carbon fiber(CF)filled poly(butylene terephthlate)(PBT)/styrene-ethylene-butylene-styrene(SEBS)triblock copolymer composites to identify the effect of CF weight fraction on the properties of PBT/SEBS.Results show that CFs are uniformly dispersed in PBT/SEBS matrix and there are no agglomerations.The melt viscosity,storage modulus,tensile strength and modulus,flexural strength and modulus and thermal stability are improved with an increase in CF loading,but the impact strength decreases.
