Abstract

Lightweight ablative materials are commonly utilized as thermal protection materials for hypersonic vehicles. Ceramizable phenolic aerogel/carbon fiber (PA/CF) composites modified with TiB₂ and B₄C were fabricated, which had the characteristics of lightweight, high strength, and low thermal conductivity. The acid-catalyzed phenol-aldehyde polymerization reaction was used to significantly shorten the gelation time, which facilitated the uniform distribution of ceramic fillers. The oxygen-consuming, oxygen-blocking, and carbon-fixing synergistic effects of TiB₂ and B₄C high-temperature ceramic reactions, as well as the multiphase ceramic structure (C-B₂O₃-TiO₂-TiC) formed, conferred excellent thermal stability (the residual weight of 58.8% at 1200 °C), oxidation resistance (the residual strength of 3.44 MPa after static ablation), and ablation resistance (the linear and mass ablation rates as low as 0.045 mm/s and 0.0115 g/s) on the composites. The lightweight, high-strength materials with anti-thermal insulation properties demonstrate significant competitiveness and application potential in the field of thermal protection.

期刊介绍： Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field. The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest. Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials. Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
