Method for producing a three-dimensional fiber reinforced ring frame component

A method for producing a ring shaped fiber reinforced frame structure having a rim, said method comprising the following steps:

• a) forming a ring prepreg having a carrier substrate (1) and a deformable fiber material on said substrate,
• b) securing, along a folding line (7), said deformable fiber material (2) having a given fiber orientation, to said substrate (1) to form a ring component,
• c) assuring with said securing that said given fiber orientation remains uniformly distributed all around said ring component,
• d) impregnating said ring component and including said carrier substrate with a resin matrix material to form said ring prepreg;
• and
• e) folding a section of said deformable fiber material (2) along said folding line out of a plane defined by said carrier substrate (1) to form said rim, and curing said ring-prepreg to finish said ring shaped fiber reinforced frame structure.
