Mullite-fiber reinforced composite high-temperature system components for 800–1700 °C extreme environments.
A dedicated data layer for composite components, covering the technical document library and the public product database.
High temperature is not a parameter — it is a threshold. Above it, what decides is materials, process depth, and how well you understand the customer's operating conditions.
Mullite-fiber composites, 400 °C+ beyond conventional heat-resistant materials
No cracking under rapid heating and quenching — 3× conventional refractories
50% lower than conventional ceramic fiber blanket — significant energy savings
No off-the-shelf SKUs. Send drawings and operating conditions — we return a design and a sample.
Not simply buying fiber and pressing it. Real customization comes from end-to-end control, from raw material to finished system.
In-house sol-gel synthesis of mullite fiber, with tunable diameter, aspect ratio and phase composition
Metal, ceramic and polymer matrix routes, matched against the temperature–mechanics–cost triangle
Compression moulding / injection / 3D printing
Multiple forming routes — complex geometries shaped directly, minimizing post-machining
Fiber characterization → composite mechanics → thermal properties → thermal cycling → condition simulation. Components ship with test reports.
We do not publish a catalogue. Tell us your temperature, atmosphere, mechanical requirements and geometric constraints — we design the material and the component backwards from there.
For ceramic sintering furnaces, heat-treatment furnaces and glass melting tanks, mullite fiber modules replace conventional refractory brick linings. Case data: wall thickness reduced 40%, furnace weight reduced 60%, gas consumption down 18–25%.
Lightweight mullite-fiber reinforced TPS tiles and insulation blankets for re-entry vehicle thermal protection, engine nozzle insulation and high-temperature wind tunnel liners. Density down to 0.3 g/cm³, dimensionally stable at 1650 °C.
Fiber-reinforced metal or ceramic matrix composites: kiln car deck slabs, furnace tube supports, crucible trays, heat-treatment fixtures. Fiber strength and modulus carried into the matrix for high-temperature strength with toughness.
Insulation layer, structural support and functional coating combined in one module. You provide chamber dimensions, temperature profile and atmosphere — we deliver install-ready modules, cutting site work by 60%+.
