Abstract
Transverse fibers are added to a pultruded part by forming a body of fibers and resin in a first die part which body is dimensioned smaller than that of the die through which the body is to be passed. A fluid including cut fibers is then applied under pressure to the body just upstream of the die so that cut fibers become integrated with the body into the spaces defined in the body. The continuous fibers, the cut fibers, and the resin are then passed through the die and become integrated into a pultruded part with the transverse cut fibers providing a transverse strength.
