The pultrusion process is a continuous manufacturing technique used to produce FRP profiles with constant cross-sections. The steps involved include:

1. Reinforcement Feeding: Continuous strands of fiberglass rovings and mats are guided from creels into the process.

2. Resin Impregnation: The fiberglass reinforcements are pulled through a resin bath where they are thoroughly impregnated with a thermosetting resin, such as polyester, vinyl ester, or epoxy.

3. Pre-Forming: The saturated fibers are organized and shaped to approximate the final profile using a series of guides and pre-forming stations.

4. Curing in Heated Die: The formed fibers are pulled through a heated steel die, where the resin undergoes polymerization (curing), solidifying into the exact shape of the die.

5. Cutting to Length: The continuous profile exits the die and is cut to specified lengths to meet application requirements.

This process ensures consistent quality, high strength-to-weight ratios, and allows for the production of complex shapes with tight tolerances.

• Corrosion Resistance: Ideal for harsh environments where traditional materials would degrade.

• Lightweight: Easier handling and reduced transportation costs compared to metal counterparts.

• High Strength: Comparable to steel in strength but with significantly less weight.

• Non-Conductive: Suitable for applications requiring electrical insulation.

• Low Maintenance: Long service life with minimal upkeep.
