FRP Pultruded Section is the manufacturing process for producing the continuous lengths of reinforced polymer structural shapes with the constant cross-sections. The raw materials are a mixed liquid resin (including resin, fillers and specialized additives) with flexible textile reinforcing fibers. The process is pull these raw materials by a heated steel forming die using a special continuous pulling device. The FRP Pultruded Section are in continuous forms, such as the rolls of fiberglass mat and doffs of fiberglass roving. As the reinforcements are been saturated with the resin mixture in the resin bath and pulled through the die, the gelation, or hardening, of the resin is initiated by the heat from the die and a rigid, cured profile is formed that bsed on the shape of the die. FRP Pultruded Sections Fiber reinforced plastic (FRP), also known as fiber reinforced polymer, is in fact a composite material constituting a polymer matrix blended with certain reinforcing materials, such as fibers. The fibers are generally basalt, carbon, glass or aramid; in certain cases asbestos, wood or paper can also be used. Most of these plastics are formed through various molding processes wherein a mold or a tool is used to place the fiber pre-form, constituting dry fiber or fiber containing a specific proportion of resin. After ‘wetting’ dry fibers with resin, “curing” takes place, wherein the fibers and matrix assume the mold’s shape. In this stage, there is occasional application of heat and pressure. The different methods include compression molding, bladder molding, mandrel wrapping, autoclave, filament winding, and wet layup, amongst others.
