ABSTRACT:
A method of producing an elongate article comprises the step of providing, by winding a filament, a plurality of superposed layers to form a hollow cylinder having open ends. At least one of the layers is formed of a circumferential winding and at least one of the layers is formed of a cross winding. The cross winding has fibers having a negative coefficient of thermal expansion and is oriented at a predetermined inclined angle to the cylinder axis. The method further comprises the step of securing to the open ends of the hollow cylinder end pieces comprised of a material having a high surface hardness and dimensional stability. The inclined angle has such a magnitude that temperature-caused changes in the axial length of the hollow cylinder compensate for temperature-caused changes in the axial length of the end pieces.
