1. High-Strength Glass Fibers

S-Class High-Strength Glass Fibers

Raw Materials: S-Class high-strength glass fibers are primarily made from silica (SiO₂) with a high proportion of alumina (Al₂O₃) and soda (Na₂O). The specific formulation and melting process create fibers with high strength and rigidity due to their high viscosity in the molten state.
Manufacturing Process: In the production of S-Class glass fibers, molten glass is drawn into long, thin fibers through a drawing process. The process controls the molten temperature, cooling rate, and fiber stretching speed to ensure high strength and rigidity. The fibers are then surface-treated to improve adhesion to matrix materials and enhance moisture resistance.
Applications: S-Class high-strength glass fibers are used in aerospace for manufacturing high-strength composite materials, such as aircraft wings and fuselage components. These composites offer an excellent strength-to-weight ratio, improving aircraft performance and fuel efficiency.

R-Class High-Strength Glass Fibers

Raw Materials: R-Class high-strength glass fibers are made from a mixture of silica, alumina, calcium, and magnesium. The formulation adjusts the proportions of these components to achieve high strength and toughness.
Manufacturing Process: During production, raw materials are melted at high temperatures and then drawn into fibers using a precise drawing process. These fibers undergo special surface treatments to enhance fatigue resistance and high-temperature stability, making them suitable for extreme conditions in aerospace components.
Applications: R-Class high-strength glass fibers are used in aerospace for components subjected to high stress, such as engine heat shields and thermal insulation materials. Their excellent fatigue resistance makes them capable of withstanding long-term mechanical loads and thermal stresses.

2. Quartz Glass Fibers

Raw Materials: Quartz glass fibers are primarily made from extremely pure silica (SiO₂), with a melting temperature typically exceeding 1700°C. To ensure electrical insulation properties and high-temperature resistance, the production process minimizes impurity inclusion.
Manufacturing Process: The production of quartz glass fibers involves melting pure silica sand in a high-temperature furnace and then drawing it into fibers. Due to their high melting point, quartz glass fibers maintain their properties stable in high-temperature environments. The finished fibers undergo rigorous inspection and treatment to ensure electrical insulation and heat resistance in high-frequency applications.
Applications: Quartz glass fibers are used in aerospace for electrical insulation and high-temperature protection applications, such as aircraft cable insulation, electronic device insulation components, and protective sheaths in high-temperature environments. Their superior electrical insulation and heat resistance ensure stability and safety of aerospace systems in extreme conditions.

3. Specialty Alkali-Free Glass Fibers

Raw Materials: Alkali-free glass fibers use formulations without alkali metals (such as sodium and potassium). These glasses typically have a higher proportion of silica (SiO₂) and alumina (Al₂O₃), providing good corrosion resistance and electrical insulation properties.
Manufacturing Process: The production process of alkali-free glass fibers is similar to that of standard glass fibers, but alkali metals are excluded from the raw materials. The fibers are melted at high temperatures and drawn into fibers. To enhance the fabric characteristics, the production process includes meticulous weaving to ensure high density and smoothness, followed by coating for corrosion resistance and electrical insulation.
Applications: Specialty alkali-free glass fibers are widely used in aerospace for interior materials, such as cabin partition panels and seat frames. Their excellent corrosion resistance and electrical insulation properties ensure the long-term stability and reliability of internal components.

4. Glass Microfiber Products

Raw Materials: Glass microfibers are usually made from high-purity silica (SiO₂) to ensure excellent non-combustibility and high-temperature resistance. The raw materials undergo special treatment to reduce impurities in the fibers.
Manufacturing Process: The production of microfibers involves drawing molten glass into fibers with diameters less than 3μm. This process controls the temperature of the molten glass, drawing speed, and cooling conditions to produce extremely fine fibers. The microfibers are then woven into fabrics and treated to enhance non-combustibility, high-temperature resistance, and chemical stability.
Applications: Glass microfiber products are used in aerospace for thermal insulation and fire protection materials, such as engine heat shields, cabin insulation layers, and fire-resistant fabrics. These materials provide exceptional thermal insulation and fire resistance, ensuring safety under high-temperature and fire conditions.
