<p>A method for manufacturing a thin structural component made of composite and intended to withstand, on the one hand, working loads and, on the other hand, accidental loadings. The method involves creating a dry fiber preform of the component that is to be manufactured, and impregnating the aforementioned perform with a matrix-forming resin by resin transfer. The perform is created by assembling at least one structural layer, a first surface reinforcing layer on a first face of the aforementioned structural layer, and a second surface reinforcing layer on a second face of the structural layer. A number of plies in the two surface reinforcing layers is first of all calculated so that the finished component will be able to withstand the accidental loadings, then a number of plies in the structural layer is calculated, with due consideration given to increases in structural strength contributed by the surface reinforcing layers so that the finished component will be able to withstand the working loads.</p> |
