pultruutio

Pultruusio is a Finnish word that translates to "pultrusion" in English. Pultrusion is a continuous manufacturing process used to produce composite materials with a constant cross-sectional shape. In this process, reinforcing fibers, typically glass, carbon, or aramid, are pulled through a resin bath where they are impregnated with a thermosetting resin. The impregnated fibers then pass through a heated die that cures the resin and shapes the material into the desired profile.

The resulting pultruded profiles are known for their high strength-to-weight ratio, corrosion resistance, and electrical insulation properties. Common applications for pultruded materials include structural components in construction, automotive parts, aerospace components, sporting goods, and electrical insulation. The continuous nature of the pultrusion process allows for efficient and cost-effective production of long, uniform parts. The type of fiber and resin used can be customized to achieve specific performance characteristics required for different applications.
