Abstract

Dans l'état actuel de la technique, les plastiques renforcés au carbone et leur très grande résistance à la traction associée à un poids relativement faible sont déjà bien connus. La présente invention exploite les caractéristiques de ces plastiques renforcés au carbone en les introduisant en tant que renforts (5) de traction dans des liants (1) de colle à bois, ce qui permet d'accroître sensiblement la résistance à la traction du liant (1) de colle à bois ainsi que la résistance à la flexion d'une poutre (1) chargée de manière à fléchir, lorsque ce renfort (5) en plastique renforcé au carbone est appliqué du côté (4) traction de la poutre (1).
