ABSTRACT:
A method of making an elongated structural element of fiber reinforced plastic material with a solid walled casing. A hollow tubular casing is generally simultaneously filled with elongated strands of continuous fibrous reinforcement and plastic material and solidified. The casing is part of the final product. An internal casing may also be used where the fiber reinforced plastic is between the internal and external casings. The elongated structural element may be initially shaped prior to solidification or after reheating reshaped into another shape such as a helical coil or spring.
