摘要： A process for producing a stampable reinforced composite semi-finished product comprising one or more plastics and chopped fibers or continuous filaments, the softening temperature of which is above the highest of the softening temperatures of the materials, comprises the steps of: depositing the fibers or filaments, especially by gravity, onto a conveyor; sprinkling particles of a powder of the plastics onto the fibers or the filaments, in a proportion of between 5% and 90% of the total weight; blending the particles with the fibers or the filaments; and heating the blend to a temperature above the softening temperatures of the materials. The blending step includes subjecting the blend to at least one electric field approximately perpendicular to the direction of advance of the conveyor.

摘要： The invention concerns an impregnation method for producing in particular a composite material comprising a fiber or filament array and a continuous matrix, rigid or flexible, with which said array is in close contact. The method is characterized in that said matrix is incorporated in said array in powder form before being transformed to constitute the continuous matrix. It consists in placing the powder and said fiber or filament in an electrostatic field with an alternating current voltage of at least 20 kV for at least 5 s.
