Method of making a complex shaped fibre reinforced thermoplastics material structure in which: a flat sheet of fibres reinforced thermoplastics material (16) is locally heated to a temperature at which the polymer material therein is plasticised, the sheet thereafter being manipulated so that it is bent or folded at the area at which it was heated. After bending, ones of said fibres of said reinforcement extending about the axis of the said bend within the outermost layer of said fibres reinforcement remaining intact and forming, with said polymer material a bead (24) extending along the length of said bend or fold. Various different ways are disclosed by which sheets shaped in the ways described may be joined with similarly shaped or flat sheets of fibres reinforced thermoplastics materials. |
