CA 2563913
The invention relates to a composite component for a vehicle body, in particular a vehicle roof, comprising an external skin (12) that is devoid of fibres and a fibre-reinforced support layer (16) that is applied to the inner face of the external skin in order to reinforce the latter. According to the invention, a fibre-reinforced reinforcement layer (18) is provided on the opposite side of the support layer (16) from the external skin (12) to add strength to the support layer. The reinforcement layer has a higher fibre content than the support layer. The invention also relates to a method for producing a composite component of this type.

Selon l'invention, une couche de renforcement (18) renforcée par des fibres est appliquée sur le côté de la couche de support (16) opposé à l'enveloppe extérieure pour renforcer la couche de support. La couche de renforcement présente une teneur en fibres supérieure à celle de la couche de support. L'invention concerne en outre un procédé de production d'une telle pièce composite.
