各向异性的C/SiC波纹点阵结构隔热性能
Thermal insulation performance of anisotropic C/SiC corrugated lattice structure
摘要
Abstract
To further explore the thermal insulation potential of C/SiC corrugated lattice structure composite materials in extreme environments such as aerospace,took C/SiC corrugated lattice structure composite materials,and investigated their thermal insulation performance using CAE simulation methods based on Fourier's heat transfer law.Firstly,under isotropic conditions,the effect of temperature gradient on heat transfer coefficient was deeply explored for steady-state and transient situations;Secondly,by comprehensively optimizing the variable constraint range,considering factors such as fiber size,fiber content,and weaving method,a simulation analysis of the heat transfer performance of the corrugated lattice structure was conducted based on anisotropy.The simulation results show that under isotropic heat transfer conditions,the insulation efficiency of the corrugated lattice structure under five high-temperature gradients reaches 13.89%to 14.12%;Under anisotropic heat transfer conditions,the temperature of carbon fiber is significantly higher than that of SiC matrix,and when the fiber content is above 600 K,the effect of temperature on the heat transfer coefficient can be ignored.The twill weaving method exhibits better insulation performance than the plain weaving method,especially under low-temperature insulation conditions.This simulation study provides certain engineering application value for the research of thermal insulation performance of aerospace composite materials.关键词
