ABSTRACT:
A method and apparatus for a low-cost, single-step method of in-line coating of pultrusion profiles to eliminate surface degradation of pultruded profiles due to outdoor exposure or corrosive attack. The method comprises pulling a combination of reinforcing fibers and resin through a pultrusion die to form a pultruded part, applying a coating to the pultruded part after it exits the pultrusion die and curing the coating on the coated pultruded part. The apparatus contains a pultrusion die for forming a pultruded part of a predetermined shape, a coating die with an exit area generally greater than the inlet area, a coating chamber located between the entrance and exit area of the coating die for applying a coating to the pultruded part, and a curing element for curing the coating on the pultruded part after it exits the coating die.
