Abstract: A windshield wiper arm assembly for wiping a windshield of a motor vehicle can include a wiper linkage head having a bore formed therein for being connected to a rotatable wiper drive shaft. A wiper arm can be coupled to the wiper linkage head through a pivot pin allowing pivoting movement of the wiper arm with respect to the wiper linkage head between a stable windshield engaged position and a stable windshield disengage position. A beam compression spring can bias the wiper arm with respect to the wiper linkage head between the stable windshield engaged position and the stable windshield disengage position. A process for fabricating a beam compression spring for a windshield wiper arm can include the steps of cross-weaving an elongate tri-axial glass fiber sock, bathing the elongate glass woven sock in a thermoset resin, and curing the bathed cross-woven sock in a heated pultrusion die to form a pultruded elongate strip.
