Abstract
A pultruded part is formed from thermosetting resin which is carried on continuous longitudinal fiber reinforcement into a die which shapes the resin and fibers into the required transverse cross sectional shape and then acts to set the resin. Some of the fibers have applied thereto a second resin material of a different characteristic so that these fibers carry the second resin into the part at localized regions to form localized regions of the second resin extending longitudinally continuously of the part. This allows a resin of an increased strength to be used at areas of increased strength requirement, for example areas of screw fastening, screw ports, junction between two legs and in order to provide a thinner part for reduced thermal transfer.
