Quartz & Ceramic Fabrics

Hexcel · HexForce®
HexForce® Quartz Woven Fabric — Radome & High-Temp Structures
Pure fused silica (quartz) woven fabric — the premier reinforcement for aerospace radomes where RF transparency, dimensional stability, and structural integrity must coexist. Quartz fiber offers an extremely low dielectric constant (ε ≈ 3.78) and near-zero dielectric loss tangent — virtually invisible to radar and microwave frequencies, outperforming both E-glass and S-2 Glass®. An exceptionally low CTE of 0.54 × 10⁻⁶/°C ensures dimensional stability through the extreme thermal cycling of aerospace and space service. Capable of continuous service to 1050°C (1920°F). Available in plain, twill, and satin weave styles; custom preform shapes for structural radome shells available on request from Hexcel Specialty Reinforcements.
