<p>A method of manufacturing a curved element made of composite material comprises the following steps: a) preparing at least one dry, flat reinforcing layer (1) with curved fibres, b) combining a resin film (2) with the dry, flat reinforcing layer, and applying heat and pressure in controlled manner so as to bring about the infusion of the resin into the reinforcing layer and to obtain at least one layer of pre-infused material (Y), c) preparing at least one prepreg layer (31, 32) with straight fibres impregnated with resin compatible with the resin of the pre-infused material, d) superimposing the layer of pre-infused material and the prepreg layer on one another so as to obtain a layered structure (1"), and e) subjecting the layered structure, arranged on a shaped support tool (30), to a polymerization cycle so as to obtain the curved element.</p> |
