Profile of the U-portion (s), element of the carrier structure of a vehicle that incorporates it and the profile manufacturing process

摘要

A profile with one or more portion(s) whose cross-sections are substantially U-shaped, locally provided with capabilities of increasing torsional rigidity and potentially flexural rigidity, a load-bearing structural element of a vehicle such as a support grille of an electrical and/or hydraulic system incorporating that profile, and a method of manufacturing that profile are provided. The profile includes at least one U-shaped portion having a slot bounded by two wings and a core and that is locally provided and capable for increasing torsional rigidity, the profile being formed of a fibre-reinforced plastic composite, having at least one cross brace formed in the slot from a single part with the wings and the core. The wings and the core are reinforced by fibres mostly oriented in the longitudinal direction of the profile, with more than 60% of the fibres oriented in a 30° to +30° angle with that direction.
