Reinforce-ment fibers may be roving,continous mat,woven robing,carbon or others.The fibers are impregnated with polymer maxtrix(resin,minerals,pigments,additives)and passed through a pre-forming station that produces the stratification necessary to give the profile the desired properties,After the pre-forming step,the resin-impregnated fibers are pulled through a heated die to polymerize the resin.
