Another core component of Industrial Composites business would be the manufacture of custom Fiberglass Reinforced Polymer (FRP) products.  Custom products are designed to exactly meet our clients specifications and requirements. 
Additional reinforcements may be added which enhance the overall quality and functionality.  Fibers provide strength, dimensional stability and heat resistance.  Additives are easily incorporated into resin systems to provide pigmentation, flame retardance, weather resistance, superior surface finish, low shrinkage and other advantageous properties.

 
Pultrusion is a continuous manufacturing process of composite materials with constant cross-sections. Reinforced fibers are pulled through a resin, followed by a separate pre-forming system and into a heated die, where the resin undergoes polymerization. 
 
The reinforcement materials are in continuous forms such as rolls of fiberglass mat and fiberglass roving. Fiberglass is an immensely versatile material which combines its light weight with an inherent strength to provide a weather resistant finish, with a variety of surface textures.  As the reinforcements are saturated with the resin mixture (“wet-out”) 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 corresponds to the shape of the die.

While pultrusion machine design varies with part geometry, the basic pultrusion process concept is described in the schematic shown below.
