Abstract: The invention relates to a casing for an aircraft engine, in particular a bypass pipe or fan casing, consisting of a plurality of hardened prepreg plies in which the fibers are oriented differently, and to a method for producing a casing of said type. In order to improve the resistance properties of the casing, especially in fire resistance tests, and reduce the amount of wasted prepreg material, at least one reinforcement ply is provided that consists of a prepreg strip having several windings, and the prepreg strip of each reinforcement ply includes a lateral overlapping portion.

Abstract: The invention relates to a fan case for an aircraft engine in the region of the fan thereof, comprising a plurality of substantially cylindrically arranged fiber-reinforced plastic layers that are joined together, wherein a reinforcement ply made of glass fiber-reinforced plastic is disposed between an inner layer and an outer layer. According to the invention, the reinforcement ply consists of at least 20 plies of a glass fiber-reinforced plastic, and that deformation layers are disposed on both sides of the reinforcement ply, which deformation layers have a lower strength than the reinforcement ply.
