Abstract
A method of forming a fibre reinforced thermoplastic composite tube (P) in which reinforcing fibres (10) and thermoplastic resin matrix material (12) are placed around a mandrel (M) to provide a composite tubular pre-form (20) on the mandrel (M) which is then passed through a heated die (30) to compact and reduce the diameter of the pre-form (20) and change the state of matrix, the mandrel (M) with the formed tube (P) thereon exiting the die and the now formed tube (P) is removed from the mandrel, the composite tubular pre-form (20) being produced by winding reinforcement fiber (10) and thermoplastic fiber (11) onto the mandrel, the thermoplastic matrix being caused to flow and then solidify on cooling.
