Dictionnaire français - anglais

Un brai (goudron de charbon, brais de pétrole ou brais mésophases), est ajouté à des fibres de carbone puis chauffé à environ 450 °C pour faire passer le brai à l'état mésomorphe et ainsi infiltrer les fibres de carbone.

A pitch, either coaltar or petroleum pitches or mesophase pitches, is added to carbon fibers and then heated to approximately 450 °C to convert the pitch to a mesomorphic condition pitch which infiltrates the carbon fibers.
