Abstract
AbstractThis 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.
