以双螺杆挤出机制备出的短碳纤维为增韧材料，以聚乳酸为基体，制备出一种新型的聚乳酸/碳纤维复合材料。通过扫描电子显微镜( SEM)、红外光谱、力学性能测试等手段，考察碳纤维含量对复合材料性能的影响。结果表明：加入碳纤维后，改变了复合材料的力学性能及耐热性，耐热性随短碳纤维含量的增大而提高，冲击强度呈现先增大后减小的趋势，碳纤维含量为5wt%左右时，复合材料的综合性能最佳。
以雙螺桿擠齣機製備齣的短碳纖維為增韌材料，以聚乳痠為基體，製備齣一種新型的聚乳痠/碳纖維複閤材料。通過掃描電子顯微鏡( SEM)、紅外光譜、力學性能測試等手段，攷察碳纖維含量對複閤材料性能的影響。結果錶明：加入碳纖維後，改變瞭複閤材料的力學性能及耐熱性，耐熱性隨短碳纖維含量的增大而提高，遲擊彊度呈現先增大後減小的趨勢，碳纖維含量為5wt%左右時，複閤材料的綜閤性能最佳。
이쌍라간제출궤제비출적단탄섬유위증인재료，이취유산위기체，제비출일충신형적취유산/탄섬유복합재료。통과소묘전자현미경( SEM)、홍외광보、역학성능측시등수단，고찰탄섬유함량대복합재료성능적영향。결과표명：가입탄섬유후，개변료복합재료적역학성능급내열성，내열성수단탄섬유함량적증대이제고，충격강도정현선증대후감소적추세，탄섬유함량위5wt%좌우시，복합재료적종합성능최가。
A new type of the PLA/carbon fiber composite material was prepared using polylactic acid as matrix, short carbon fiber was prepared by double screw extruder as the toughened materials, and its performance was studied under the effects of short carbon fiber content changed by SEM micrograph, XRD and Flexural strength texting. The results showed that the performance of the PLA/carbon fiber composite material was changed, heat resistance increased and the impact strength increased first, then decreased with the increase of the content of the short carbon fiber. The content of short carbon fiber was about 5 wt%, performance of this composite material was best.
