Dispelling the Myths and Defining What's Important to Consider When Purchasing Pultrusion Equipment

摘要

Pultrusion is an automated and continuous process to manufacture reinforced plastic structural shapes having a constant cross-section. In solid rods or profiles pultruded parts are used in a wide variety of markets and applications. One or several different forms of continuous fiber reinforcement, such asrovings, mats, woven rovings, fabrics, braids and/or cloths, with the type and amount of reinforcement are used to reinforce a polymer (resin) to achieve a desired set of performance properties. Surfacing veils are used to give the molded part a smooth, resin-rich surface for additional corrosion resistance or UV protection. Typically, the process consist of the following steps:
