A multiaxis, multilayer fibre preform for high stressed composite components has fibres aligned according to the principal stresses in not only the X and Y axes, but also the Z axis. Fibres in the X and Y directions are aligned according to stresses in these directions and built up and embroidered in layers on a carrier layer (10). In local areas of high stress reinforcing threads (8) are embroidered in the Z direction through the fibre lay down in the other two directions (X,Y) to prevent delamination of the eventual composite component. In a process for manufacturing the preform the reinforcing fibres are placed along the X and Y directions according to a prescribed pattern and embroidered onto a carrier layer (10). Reinforcing fibres are then embroidered through the X and Y layers in the Z direction.

Title
Multilayered fibrous preform having at least part of the reinforcement extending along the z axis and process for its manufacture
