A vehicle crossmember is made from continuous fiber-reinforced polymeric material without the need for metallic structural reinforcements. The crossmember includes more than one fiber-reinforced material composition, including different amounts and/or types of fiber reinforcements along different lengthwise portions of a crossbar of the crossmember. Attachment points and stiffening ribs can be overmolded onto surfaces of the crossbar before assembling two halves of the crossbar together to form the crossmember.

Composite vehicle crossmember

The present invention relates to a dashboard crossmember () for a vehicle, including a crossbar () as well as at least one connection flange () designed to enable said crossbar to be attached to the body of said vehicle, said crossmember being characterized in that said crossbar () includes a bearing web () made of a fiber-reinforced composite material including continuous libers () arranged within a matrix (), and preferably results from the assembly of a plurality of preformed basic parts () each produced by bending a composite material lap piece () about a single direction of the space so as to avoid overstretching or dislocating the network of fibers () of each of said laps.

Crossmember made of a fiber-reinforced composite material for a vehicle dashboard and method for manufacturing same

The invention relates to a vehicle dashboard crossmember () including a crossbar which extends lengthwise along a generatrix line (G) that is directed substantially along the width of the vehicle body and transversely relative to the direction of travel of said vehicle, as well as at least one connection flange () designed to enable said crossbar () to be attached to said body, said crossbar () consisting, over at least a portion of the length thereof, of a load-bearing web () that has a side wall () rounded about said generatrix line (G) so as to have, in a cross-section perpendicular to the generatrix line, a first arm () and a second arm () that are connected to one another via a common connection portion () and which thus define a cavity (), and of a reinforcing brace () made of a fibrous composite material.
