In aerospace scenarios, thermal protection and insulation face extreme conditions such as high temperature, strong vibration, and complex thermal cycling. Ceramic fiber blankets, with high-temperature resistance, low weight, and low thermal conductivity, are often used for spacecraft thermal protection structures, engine bays, and insulation layers for high-temperature piping. Real performance depends on three key capabilities: high-temperature stability, mechanical integrity, and dimensional consistency. Xinhui's ceramic fiber blankets are designed around aerospace assembly and service needs to provide practical, engineered solutions.

Aerospace requirements for ceramic fiber blankets focus on three points. First, high-temperature and long-term stability: under sustained service above 1200 C, the material should not crack, powder, shrink noticeably, or drift in performance. Second, lightweighting: every 1 kg reduced can directly improve payload efficiency and structural margin. Third, low thermal conductivity: under high thermal gradients, it must still insulate effectively to keep precision instruments and sensitive components in a controllable temperature range. Standard products often fall short due to raw material purity, fiber diameter distribution, and blanket uniformity. Xinhui improves engineering fit through coordinated optimization of material system and forming process.

In the material system, it uses alumina with purity >=99% and crystalline silica, and introduces zirconia reinforcement to improve high-temperature structural stability and thermal shock resistance. Long-term service temperature reaches 1400 C, and short-term resistance can exceed 1600 C, covering typical reentry heat environments and engine bay high-temperature zones.

In the process, ultrafine fiber blowing is used to control fiber diameter at 3-4 um. High-density needle punching enhances structural strength and uniformity, achieving bulk density as low as 128 kg/m^3, about a 15% weight reduction compared to similar products. At 200 C, thermal conductivity can be as low as 0.035 W/(m K), which significantly reduces heat transfer when used as an insulation layer and improves cabin thermal stability and component reliability.

To meet aerospace assembly dimensional consistency and mating requirements, Xinhui supports custom thickness of 10-50 mm and width of 1200-2000 mm, with dimensional tolerance controlled within +/-0.5 mm. It contains no heavy metals or volatile substances, meeting stricter environmental and cleanliness requirements.

The performance ceiling of aerospace depends on the stability floor of materials under extreme conditions. Oriented toward high-temperature insulation R&D and engineering delivery, Xinhui can provide ceramic fiber blanket specifications and application solutions for spacecraft parts manufacturing, aviation equipment, and high-temperature system integration, using high-performance insulation to support reliable operation of critical areas and system weight reduction goals.
