碳纤维增强聚碳酸酯复合材料在高温中的准静态压缩强度
Quasi-static Compression Strength of Carbon Fiber Reinforced Polycarbonate Composites in high temperature
摘要
Abstract
Thermoplastic composites are prepared by using carbon fiber plain weave fabric and carbon fiber unidirectional fabric in combination with polycarbonate separately.The composites include carbon fiber reinforced polycarbonate plain weave laminate,unidirectional laminate and orthogonal laminate.A self-made high-tempera-ture device is collocated with MTS(Material Testing System)to investigate the out-of-plane quasi-static com-pression behavior of the three composites at four temperatures:20℃,120℃,150℃and 180℃.The influence of structure and temperature on the performance is analyzed and failure modes are explored under different condi-tions.The results show that the maximum stress and compressive modulus of the carbon fiber reinforced polycar-bonate plain weave laminate are similar to those of the orthogonal laminate,both of which are higher than those of the unidirectional laminate.Additionally,temperature has a significant impact on the out-of-plane quasi-static compression performance of the three composites.As the temperature increases,the quasi-static compressive modulus and maximum stress decrease.关键词
