摘要

C/SiC点阵结构复合材料具有轻质、高强、防热、抗烧蚀等功能

有望应用于未来高超声速飞行器的热防护系统中.采用纤维束缝合工艺和先驱体浸渍裂解法（PIP）制备了C/SiC四棱锥点阵结构复合材料.将C/SiC点阵结构复合材料试件分别在1 200℃和1 600℃下进行热处理30 min

对高温热处理后的C/SiC四棱锥点阵结构复合材料压缩性能进行了实验研究

并与未进行热处理材料的压缩性能进行了比较.实验结果表明：高温热处理会引起C/SiC四棱锥点阵结构复合材料压缩性能的下降

但1 600℃热处理后材料的强度明显高于1 200℃热处理后材料的强度.

Abstract

C / SiC composite lattice core sandwich structures are considered as promising candidates for future high temperature applications of thermal protection systems such as hypersonic vehicles because of their lightweight

superior strength

thermal protection and erosion resistance properties. C / SiC composite lattice core sandwich structure was fabricated by a technique that involved the polymer impregnation and pyrolysis（ PIP） method and interweaving process. The C / SiC composite lattice core sandwich structure were then heat treated at 1 200℃ and1 600℃ for 30 min respectively. The experimental compressive mechanical properties of C / SiC composite lattice core sandwich structure after heat treatment were compared with those at room temperature. It is found that there is obvious decrease for the C / SiC composite lattice core sandwich structure after heat treatment. However

the compressive strength C / SiC composite lattice core sandwich structure after heat treatment at 1 600℃ is higher than that at 1 200℃.
