【摘要】 利用山东瑞城生产的中间相沥青基碳纤维(6K)预浸料和T800H碳纤维(6K)预浸料制备了单向复合材料板，并对其性能进行了测试对比。结果表明沥青基碳纤维复材板0°方向的拉伸强度、ILSS、弯曲强度和压缩强度均低于T800H,但其模量均明显高于T800H;导热性能方面，沥青基碳纤维复合板0°方向导热率为311 W/(m·k),而T800H仅为7 W/(m·k)。中间相沥青基碳纤维是国内量产成功的新型特种材料，本文为其使用方向提供了借鉴。更多还原

【Abstract】 In this paper, unidirectional composite plates were prepared with mesophase pitch-based carbon fiber(6 k) prepreg and T800 H carbon fiber(6 k) prepreg produced in Shandong Ruicheng, and their properties were tested and compared. Results show that the tensile strength, ILSS, bending strength and compressive strength of mesophase pitch-based carbon fiber composite plates at 0° direction are lower than those of T800 H, but their modulus are obviously higher. In terms of thermal conductivity, mesophase pitch-based carbon fiber composite plate at 0 ° direction is 311 W/(m·K), while that of T800 H is only 7 W/(m·K). Mesophase pitch-based carbon fiber is a new type of special material successfully produced in China. This paper provides reference for its application direction.更多还原
