1. Overview of Quartz Fiber

● Material and Properties: Quartz fiber is made from high-purity silica and possesses high-temperature resistance (600-1050℃) and excellent electrical insulation properties.

● Application Fields: Widely used in high-tech fields such as aerospace, missile ablation materials, and radar domes.

2. Developmental Needs for Structural Materials

● Requirements for New Materials: With the development of aviation, aerospace, and nuclear energy technologies, higher requirements have been placed on structural materials, including high strength, high modulus, high-temperature resistance, corrosion resistance, and lightweight.

● Role of Quartz Fiber: In addition to glass fibers, carbon fibers, and boron fibers, quartz fiber is also one of the high-performance inorganic fibers that meet these demands.

3. Characteristics of Quartz Fiber

● Appearance and Workability: Quartz fiber is a white, soft, and glossy weavable fine silk.

● Physical and Chemical Properties: It has excellent physical and chemical properties and is made from high-purity silica by melting and drawing into single filaments with diameters ranging from 1-15μm.

4. Performance and Applications of Quartz Fiber

● High-Temperature Resistance: Quartz fiber can be used at temperatures ranging from 600-1050℃ for long periods. When the temperature exceeds 1600℃, it begins to sublimate. It is used for ablation materials in aerospace vehicles and intercontinental missile re-entry atmospheres.

● Electrical Insulation: It has superior electrical insulation properties, with the best dielectric constant and dielectric loss among all mineral fibers. It is suitable for radar domes, electromagnetic windows, antenna feeds, and low-dielectric products.
