Advanced Composites

With characteristics including rot resistance, noncombustibility, high strength and durability, fiberglass fabrics can meet critical and unusual design needs for the military. Structural parts, armor reinforcement, thermal and electrical insulation, and shipboard insulation are just a few of the many military applications of fiberglass fabrics of both "E" and "S-2" types.

Astroquartz II Fabrics

Astroquartz fabrics offer better solutions to high heat, high strength problems. The aerospace industry relies on Astroquartz quartz fiber products made from high purity (99.95% SiO2) quartz crystals. An outstanding reinforcement for high temperature and ablative space and missile applications, Astroquartz products are recommended when low dielectric loss properties are required, such as microwave transmission in radome and antenna applications. Other applications include insulation for the space shuttle, cable tray insulation for nuclear power plants and laminated fabric for circuit boards. Conform formable Astroquartz fabrics are recommended for use in preforms for resin transfer molding (RTM), press molding and tooling applications.

Astroquartz III Fabrics

Astroquartz III fabrics, a new generation of quartz fabrics, are a low-cost alternative to the nine micron fiber Astroquartz II fabrics. Based on 14 micron filament yarns, Astroquartz III fabrics are woven from high tensile strength, high purity (99.95%) fused silica fiber yarns. Two fabric styles are available – 4503 and 4581. Astroquartz III fabrics feature many of the successful attributes of Astroquartz II fabrics. The epoxy laminates made from the new Astroquartz III styles feature the same mechanical properties as in Astroquartz II styles. Laminate test results are available upon request. Astroquartz fabrics are known for their low dielectrics, near zero coefficients of thermal expansion, high temperature performance and excellent mechanical properties in composites.
