Abstract

Carbon-fiber-reinforced polymers (CFRPs) are among the most promising structural materials for aerospace applications, particularly for systems operating at cryogenic temperatures, where high strength, low mass, and low thermal conductivity are essential. In this work, the thermal conductivity of a set of CFRP samples: T300 (67% 0\(^\circ \)), T700 (62% 0\(^\circ \)), HS40 (67% 0\(^\circ \)/0\(^\circ \)/0\(^\circ \)/90\(^\circ \)), HS40 (62% 0\(^\circ \)/0\(^\circ \)/0\(^\circ \)/90\(^\circ \)), M55J (0\(^\circ \)), HS40 (67% 0\(^\circ \)), HS40 (62% 0\(^\circ \)), IMA (0\(^\circ \)), and IMA (90\(^\circ \)), was measured over the temperature range 100 mK to 20 K. Thermal conductivities were extracted using a new analysis method developed. The resulting temperature-dependent behavior for each sample is presented and compared with the existing literature.

各种cfrp在100 mK至20 K范围内的热导率

碳纤维增强聚合物（CFRPs）是航空航天应用中最有前途的结构材料之一，特别是在低温系统中，高强度、低质量和低导热性是必不可少的。在本工作中，一组CFRP样品的导热系数：T300 (67% 0\(^\circ \)), T700 (62% 0\(^\circ \)), HS40 (67% 0\(^\circ \)/0\(^\circ \)/0\(^\circ \)/90\(^\circ \)), HS40 (62% 0\(^\circ \)/0\(^\circ \)/0\(^\circ \)/90\(^\circ \)), M55J (0\(^\circ \)), HS40 (67% 0\(^\circ \)), HS40 (62% 0\(^\circ \)), IMA (0\(^\circ \)), and IMA (90\(^\circ \)), was measured over the temperature range 100 mK to 20 K. Thermal conductivities were extracted using a new analysis method developed. The resulting temperature-dependent behavior for each sample is presented and compared with the existing literature.
