Abstract
A process for producing reinforced plastics tube for use, inter alia, as a transmission shaft wherein the tube is produced by winding on to a core reinforcing fibres preferably of carbon impregnated with a curable plastics at predetermined winding angles <35.degree. and then winding on to the reinforcing fibres at angles between .+-.80.degree. and .+-.90.degree. a peripheral winding of a material which is relatively resilient with respect to the reinforcing fibres and which has a high coefficient of thermal expansion. The tube so formed is then heat cured. Fittings are secured to the ends of the tube and the ends may be reinforced with a carbon fibre structure.
