Abstract: Disclosed are composite materials that can exhibit low transmission energy loss and can also be temperature resistant. The composites include reinforcement fibers held in a polymeric matrix. The polymeric matrix can include an amorphous polymer component. Also disclosed are methods of forming the composites. Methods can include forming amorphous thermoplastic polymer fibers, forming a fabric from the fibers, combining the fabric with reinforcement fibers, and molding the structure thus formed under heat and pressure such that the amorphous thermoplastic polymer flows and forms a polymeric matrix incorporating the reinforcement fibers. The composites can be molded from multi-layer structures that can include layers of differing materials, for instance layers formed of polyaramids, fiberglass, or carbon fiber wovens or nonwovens. The composites can advantageously be utilized in low loss dielectric applications, such as in forming circuit board substrates, radomes, antennas, and the like.

Abstract: A glass fiber and a method of manufacturing a glass fiber for reinforcing a transparent composite matrix are disclosed. The glass fiber includes a first glass material having a first set of mechanical properties including a first modulus and a first coefficient of thermal expansion (CTE) and a second glass material having a second set of mechanical properties including a second modulus and a second CTE. The second glass material forms a substantially uniform coating on the first glass material. The second CTE is less than the first CTE. The glass fiber is formed by reducing the cross-section of a glass fiber preform of the first glass material coated with the second glass material by hot working. Because of the selected difference in the CTE's, the first glass material imparts a compressive force upon the second glass material, which improves the strength of the glass fiber.
