Stampable reinforced thermoplastic sheet, at least one face of which comprises, from the outside to the inside, at least three successive layers abc, in which:

Stampable reinforced thermoplastic sheet and articles obtained from said

An apparatus for the manufacture of sections of thermoplastic resin reinforced with continuous fibers. The apparatus includes coating rovings, having their fibers previously arranged in the form of a sheet by passage through a baffle zone having at least one transverse baffle, in a coating zone fed with a molten thermoplastic, then, to ensure impregnation of each of the fibers of the rovings, the coated rovings are passed into a forced impregnation zone having at least two baffles parallel to the baffle in the baffle zone prior to passing into the channel for shaping the final product.

Apparatus for the manufacture of sections of thermoplastic resin

In the process for the manufacture of a polyamide composite material reinforced with long fibers, the improvement comprising impregnating the fibers with a polyamide oligomer or prepolymer, heat-treating the impregnated fiber to increase the length of the polymer chain, and then shaping the impregnated fiber by pultrusion.

Process for the manufacture of polyamide composite material reinforced

The invention is a process for the manufacture of sections of thermoplastic resin reinforced with continuous fibers and the equipment for carrying out the process. The process consists of coating rovings, having their fibers previously arranged in the form of a sheet, in a coating zone fed with a molten thermoplastic, then, to ensure impregnation of each of the fibers of the rovings, the coated rovings are passed into a forced impregnation zone prior to passing into the channel for shaping the final product.
