摘要：<p>The barrier has a rising pole in the form of a straight tube (110) of circular section, made from 55 - 65 per cent by weight of glass fibres, 45 - 35 per cent by weight of carbon fibres, and resin. The tube has an inner layer (112) of lengthwise parallel fibres, a middle layer (116) of angled spiral fibres, and an outer layer (116) of lengthwise parallel fibres, made and polymerised together in the resin to form a composite one-piece tube, which has a protective inner sleeve.</p>
