Quartz Fiber
Quartz Fiber Materials for Thermal Protection and Advanced Composites
High-purity quartz fiber is a high-performance inorganic fiber with excellent temperature resistance, thermal stability, dielectric properties, chemical resistance, and low thermal expansion. These characteristics make quartz fiber suitable for applications where conventional glass fiber materials cannot provide the required combination of thermal and electrical performance.
Our quartz fiber range includes continuous quartz fiber yarn, roving, woven fabrics, chopped fiber, felt, and other quartz fiber materials for high-temperature insulation, composite reinforcement, electrical insulation, and thermal protection systems.
Quartz fiber materials are particularly suitable for aerospace structures, radomes, antenna windows, thermal protection systems, furnace insulation, high-temperature cables, semiconductor equipment, and advanced composite applications where low dielectric properties and high-temperature performance are required.
Quartz Fiber Reinforcement for Aerospace, Thermal Protection and Electrical Insulation
Our Quartz Fiber portfolio provides high-purity fiber materials for demanding applications requiring a combination of high-temperature resistance, low dielectric properties, thermal shock resistance, chemical stability, and lightweight reinforcement.
The range can include quartz fiber yarn, quartz fiber roving, quartz fiber fabric, chopped quartz fiber, quartz fiber felt, and other forms designed for weaving, braiding, filament winding, pultrusion, composite reinforcement, thermal insulation, and specialized fabrication processes.
Quartz fiber typically features very high silica purity and excellent dielectric characteristics, making it particularly suitable for aerospace radomes, antenna windows, electromagnetic-transparent structures, and high-frequency communication components. Saint-Gobain, for example, identifies quartz fiber as a material for aerospace radomes because of its combination of structural performance and low dielectric properties.
Its high-temperature stability also makes quartz fiber suitable for thermal protection systems, aircraft engine insulation, fireproof barriers, high-temperature cables, furnace insulation, semiconductor equipment, and exhaust thermal protection. Quartz fiber products are also used in filtration and high-temperature sealing applications where thermal and chemical resistance are important.
Quartz fiber fabrics and other reinforcement forms can be incorporated into resin-based composite structures where low dielectric response, dimensional stability, heat resistance, and lightweight construction are required. These applications include aerospace composite structures, radomes, antenna windows, electromagnetic-transparent components, and other advanced composite systems.
Our quartz fiber materials are suitable for industries including aerospace, defense, semiconductor manufacturing, electronics, high-frequency communications, thermal processing, automotive, energy, and advanced composite manufacturing.
