Research progress on phenolic impregnated carbon fiber ablation composite

高超音速飞行器、高马赫数飞船返回舱以及深空探测等技术的发展对热防护材料的性能提出了新要求,轻质炭化材料应运而生并逐渐成为热防护领域的关键材料,酚醛浸渍碳纤维烧蚀体(phenolic impregnated carbon ablator, PICA)是轻质炭化材料的典型代表。本文对PICA的研究进展进行了综述,首先概述了PICA的分类及其烧蚀机理,其次重点总结了PICA的改性方法,最后展望了PICA的发展趋势。

The development of hypersonic aircraft, high Mach number spacecraft return capsule and deep space exploration has brought new demands of the performance of thermal protection materials. Lightweight carbonized materials have emerged and gradually become key materials in the field of thermal protection. Phenolic impregnated carbon fiber ablation body(phenolic impregnated carbon ablator, PICA) is a typical representative of lightweight carbonized materials. This article reviews the progress of PICA materials. Firstly, it summarizes the classification of PICA materials and its ablation mechanism;secondly, it summarizes the modification of PICA materials;finally, it looks forward to the development trend of PICA materials.
