A computer-controlled method of component manufacture comprises winding a thread of material around a mandrel 7 to form a first layer 17 of adjacent turns and a subsequent layer 29 of wound strands atop the first. A laser beam (11, fig 2) is applied between adjacent turns of each layer to attach them at predetermincd points 21,23,31,33. The two layers may further be attached to one another by laser welding and the two layers may have threads orientated differently from one another. The material of the thread may be a matrix coated fibre, preferably silicon carbide, surrounded by metal. The two layers may be further secured together using metal based powder melted between the layers (37, fig 7). Further independent claims are included for a component formed by the method and for a computer program, storage medium and apparatus for performing the method. |
