This article reports a novel lightweight integrated multifunctional composite (LIMC) with good thermal ablative and insulating properties for high temperature extreme environment. LIMC, which is an integrated woven carbon fiber preform reinforced phenolic aerogel composites, was prepared using vacuum impregnation and ambient pressure drying. The as-prepared LIMC consisted of a dense surface layer exposed to environment, and a lightweight insulation zone to manage the heat load. The influences of weaving parameter and resin structure of LIMC on thermal protection and insulting performance were investigated. The results demonstrated that LIMC exhibited excellent ablation and insulation properties, and the weaving parameter and resin structure can affect integrated thermal protection and insulating performance. The 3D orthogonal recession layer with dense aerogels can improve the ablation resistance, while the 2.5D layer-layer angle-interlock with light aerogels can increase the insulation behavior of LIMC. The novel LIMC presents wide application prospects in the field of thermal protection and heat insulation.

轻质集成多功能复合材料编织参数和树脂结构对极端环境热防护性能的影响
本文报道了一种新型轻质集成多功能复合材料（LIMC），具有良好的热烧蚀和绝缘性能，适用于高温极端环境。LIMC是一种集成编织碳纤维预制体增强酚醛气凝胶复合材料，采用真空浸渍和常压干燥制备而成。所制备的 LIMC 由暴露于环境的致密表面层和用于管理热负荷的轻质隔热区域组成。研究了LIMC的编织参数和树脂结构对热防护和绝缘性能的影响。结果表明，LIMC表现出优异的烧蚀和绝缘性能，编织参数和树脂结构会影响综合热防护和绝缘性能。具有致密气凝胶的3D正交衰退层可以提高耐烧蚀性，而具有轻质气凝胶的2.5D层-层角互锁可以增加LIMC的隔热性能。新型LIMC在热防护和隔热领域具有广阔的应用前景。
