In the aerospace field, extreme working conditions impose strict requirements on the performance of insulation materials. Ceramic fiber blankets have become the core material for spacecraft thermal protection systems and engine compartment insulation due to their high temperature resistance, lightweight, and low thermal conductivity. The application effect depends on the high temperature stability, mechanical strength, and dimensional accuracy of the material. The ceramic fiber blanket of Rosewool Insulation Refractory Co.Ltd is providing a reliable solution for the industry with the advantage of accurately adapting to aerospace needs.
The core requirements for ceramic fiber blankets in the aerospace industry are focused on three aspects: first, high temperature resistance, which requires long-term stability at extreme temperatures above 1200 ℃, without cracking or powdering; The second is the lightweight feature, which can significantly improve the spacecraft's carrying efficiency for every 1kg reduction in material weight; Thirdly, the low thermal conductivity ensures that the precision instruments inside the cabin are in a suitable temperature environment. Ordinary ceramic fiber blankets on the market often have insufficient purity and uneven fiber structure, making it difficult to meet these requirements. However, Rosetexwool has made targeted breakthroughs in technical difficulties.
We use alumina and crystalline silica with a purity of ≥ 99%, combined with zirconia reinforcement components, to make ceramic fiber blankets through special processes. The long-term use temperature can reach 1400 ℃, and the short-term temperature resistance can exceed 1600 ℃, fully suitable for the high temperature environment of spacecraft re-entry into the atmosphere or engine operation. At the same time, through ultra-fine fiber blowing technology (fiber diameter 3-4 μ m) and high-density needle punching molding, the product has a volume density as low as 128kg/m ³, which is 15% lighter than similar products in the industry, effectively helping spacecraft reduce weight. In addition, its thermal conductivity at 200 ℃ is as low as 0.035W/(m · k), which can efficiently block heat transfer and ensure stable operation of equipment in the cabin.
Not only that, Rosetexwool can also customize products with different thicknesses (10-50mm) and widths (1200-2000mm) according to the needs of aerospace projects, and the dimensional tolerance is controlled within ± 0.5mm to meet the requirements of precision assembly. The product has passed SGS aerospace grade material testing and does not contain heavy metals or volatile substances, meeting strict environmental standards.
The development of the aerospace industry cannot do without the support of high-quality materials. Rosetexwool, with its deep research and development of materials for extreme working conditions, can provide customized ceramic fiber blanket solutions for aerospace component manufacturers and aviation equipment enterprises. Looking forward to working together with you to help aerospace projects overcome technological bottlenecks with high-performance insulation materials and build new heights in China's aerospace industry!
