Section 1: Introduction to Epoxy Glass Fiber Drawn Rod
Epoxy glass fiber pull rods are made of inorganic glass fiber synthetic yarn, felt, and fabric as reinforcing materials. They are impregnated with solvent-free resin on molds and continuously baked using the "pull forming" process, then pressure-set to form products with cross-sectional shapes, such as round rods, square bars, slot wedges, I-beams, and槽-shaped parts, as well as various complex-shaped products. They feature extremely high mechanical strength in the fiber direction, good dielectric properties, and can be available in any length.
