ABSTRACT:
A method of producing a plastic leaf spring for motor vehicles comprising forming a plurality of cured duromeric plastic strips reinforced with high strength fibers aligned substantially in the direction of the maximum elongation or compression of the fibers occurring under spring load at least in essential resilient regions of the spring, the said resilient regions being said strips bonded together by an adhesive and eventually also being bonded to a second, more resilient element and/or to another element and a process for its preparation.
