Abstract
From 3 to 25 g/m.sup.2, in particular from 5 to 10 g/m.sup.2 of a pulverulent reactive hot-melt composition including a prepolymer and a hardener for the latter are applied onto one or two faces of textile reinforcement. The hardener becomes active only at a temperature above that at which the powder softens to become tacky. This powder on one or two faces makes it possible in particular to preform the reinforcement before it is employed for the manufacture of an article made of composite material.
