Ultra-High Temperature Ceramics and Composites for Hypersonic and Aerospace Applications
This community develops structural materials that retain mechanical integrity while resisting extreme heat, oxidation, and ablation, primarily for hypersonic flight and aerospace propulsion systems.
The research focuses on silicon carbide, silicon nitride, and carbon-carbon composites, often reinforced with carbon fibers or zirconium carbide. Key methods include spark plasma sintering, plasma sintering, and chemical vapor deposition for protective coatings. The work addresses specific failure modes such as oxidation behavior, ablation resistance, and thermal conductivity management. Recent efforts also explore additive manufacturing techniques and the integration of phenolic resins for thermal insulation and structural support in high-temperature environments.
The largest share of this community's output is found in carbon research, accounting for 1.2% of all carbon research, and silicon research, at 1.6% of all silicon research. Carbon also contributes the highest paper count within this group, with 9,844 papers.
The community comprises 25,577 papers, publishing most frequently in Carbon, Ceramics International, and the Journal of the American Ceramic Society.
Recent work continues to focus on enhancing ablation resistance in zirconium carbide-modified composites and developing high-thermal-conductivity silicon nitride ceramics, with specific attention to oxidation resistance in niobium-silicon alloys and the mechanical properties of additive-manufactured ceramic structures.
