Abstract:
1. A method for manufacturing a fibre-composite component, wherein the method comprises the following steps: providing at least one structural component extending along at least one edge section of a recess to form at least a frame component along the edge section of the recess; and providing a skin section formed of a plurality of layers of prepreg semifinished mats, each prepreg semifinished mat including a plurality of fibres extending longitudinally in a substantially parallel configuration, where the skin section is connected to said structural component such that the structural component and layers of the skin section are formed as one piece, wherein the step of providing the skin section includes: applying the layers of the prepreg semifinished mats as skin-section blanks to a mould to form the skin section, wherein the prepreg semifinished mats in an initial state are such that the fibers extend along a longitudinal direction of the prepreg semifinished mats, applying a multitude of the prepreg semifinished mats as layers in such a manner that at least some of the fibres extend along the longitudinal direction toward the edge section of the recess, and extend in a curved path with a change in direction of at least 15 degrees relative to the longitudinal direction as such fibres are closer to the edge section of the recess, and extend along the edge section of the recess along lines of equal stress, when exposed to external forces, which lines lead around the edge section of the recess; pre-curing the prepreg semifinished mats in order to stabilise at least one skin-section blank; applying layers of a prepreg semifinished product to form the structural component a cured skin-section blank; curing the assembly comprising the prepreg semifinished mats for the skin section and the prepreg semifinished product for the structural component.
