摘　　要：综合考虑碳纤维材料的加工适应性以及对基体力学性能改善的能力,分别选取了短切碳纤维和碳纤维粉末作为增强相,比较了它们对于PP的增强效果以及加工的难易,通过测定拉伸性能和冲击韧性考察了短切碳纤维的含量以及碳纤维粉末的含量对各自复合材料力学性能的影响。结果表明,随着碳纤维含量的增加,两种复合材料的冲击韧性以及拉伸性能都呈先增加后减小的趋势,短切碳纤维作为增强相对于基体树脂的力学性能增强效果更为显著,碳纤维粉末作为增强相的复合材料加工适应性强,性能更加稳定,该研究对碳纤维制品的实际注塑生产具有十分重要的意义。In consideration of the difficulty of producing and the ability of property improving,short carbon fiber and carbon fiber powder were selected as reinforced phase to compare the improving effect and producing difficulty of them,the influences of short carbon fiber/carbon fiber powder on the mechanical properties of these two composite materials were discussed by determining tensile property and impact toughness. The results show that with the content of carbon fiber increase,the impact toughness and the tensile property of these two composite materials increase first and then reduce,the reinforce effect of mechanical property are more obvious if short carbon fiber is chosen as the reinforced phase,on the contrary,when carbon fiber powder is chosen to be reinforced phase,a composite material with more stable property and easier producing adaptability is acquired,which is instructive to the actual injection production of carbon fiber products.
