PULTRUDE Meaning and
Definition
-
Pultrude is a verb that refers to the process of manufacturing composite materials by pulling continuous fibers through a resin bath and then into a shaping die or mold. This method is commonly used to produce strong, lightweight, and corrosion-resistant products made from a combination of fibers, such as fiberglass, carbon fiber, or aramid, and a resin matrix.
The process begins with the continuous fibers being pulled from spools and passed through a liquid resin bath, ensuring complete impregnation of the fibers. The impregnated fibers then enter a heated die, where the resin undergoes curing or polymerization, making it solidify and bond the fibers together. The die shapes the composite into the desired form, which can be a constant cross-section, such as a rod or tube, or a more complex shape like a beam or panel.
Pultrusion offers several advantages over traditional manufacturing techniques, such as increased strength-to-weight ratios, excellent dimensional stability, and resistance to environmental factors like moisture, chemicals, and UV radiation. It is widely utilized in industries such as construction, aerospace, automotive, marine, and infrastructure, where lightweight and durable materials are crucial.
Overall, pultrude describes the method used to produce composite materials by pulling impregnated fibers through a forming die, resulting in highly versatile and efficient products with a wide range of applications.

Etymology of PULTRUDE
The word "pultrude" is a combination of two words: "pull" and "extrude". The term was coined in the 1950s as a verb to describe a specific manufacturing process for producing continuous composite materials or profiles. In this process, a reinforcing fiber material, such as fiberglass, is pulled through a resin bath and then extruded using heat and pressure. The resulting product is a continuous reinforced composite material with high strength-to-weight ratio, which is commonly used in various industries. Thus, "pultrude" is a blend of "pull" and "extrude" to describe this unique manufacturing technique.
