초록 ▼

This invention relates to composite materials formed by thermoplastic materials reinforced by fibers, and to methods and apparatus for forming such materials, where the thermoplastic and fiber components are such as to impart to the composite materials enhanced strength as compared with materials made previously to this invention. An important distinguishing characteristic of the disclosure is that advancing heated fiber is directed to move in one direction and while a flow of heated thermoplastic material is directed to move in a direction opposite to and in intimate impregnating enclosure of the advancing heated fiber, so that shear forces arising between the advancing heated fiber and the directed flow of thermoplastic material promote wetting and impregnation of the fiber by the thermoplastic material.

A method for producing a fiber reinforced thermoplastic material comprising providing an impregnation chamber having a plurality of elongate impregnation passageways, each with an entrance end and an exit end, directing a plurality of strands of continuous filament fiber along a predetermined advancing path of travel into and through the respective passageways, each entering through the entrance end and exiting through the exit end, directing molten thermoplastic polymer material from an extruder into the respective impregnation passageways at a location adjacent the exit end thereof and in a direction toward the entrance end in opposing, countercurrent direction to the advancing strands of fiber and in intimate contact with the respective advancing strands of fiber for wetting and impregnating the strands of fiber with the thermoplastic material, engaging and turning the strands of fiber through a predetermined angle to squeeze the fiber and thermoplastic material together, joining the strands of impregnation fiber bundle into one bundle, and pulling the joined impregnated fiber bundle from the exit end of the impregnation chamber while maintaining tension on the advancing strands of fiber in the impregnation passageway as they contact the molten thermoplastic polymer. Apparatus for producing a fiber reinforced thermoplastic material comprising an impregnation chamber having an elongate impregnation passageway with an entrance end and an exit end, an exit die with a restricted die opening mounted at the exit end of said impregnation passageway, a supply of continuous filament fiber, means for directing the fiber along a predetermined advancing path of travel into and through said impregnation passageway, entering through said entrance end and exiting through the restricted die opening of said exit die, an extruder for providing a supply of molten, thermoplastic polymer under pressure, means for directing molten thermoplastic polymer material from said extruder into said impregnation passageway at a location adjacent said exit end thereof so that the molten polymer flows along the passageway toward said entrance end thereof in counter-current relation to the direction of movement of the advancing fiber and in intimate contact with advancing fiber and the flow of thermoplastic material promote wetting and impregnating of the fiber with the molten thermoplastic polymer, and means on the downstream side of said impregnation chamber for pulling the polymer impregnated fiber from the impregnation chamber and through said exit die and for maintaining tension on the advancing fiber in the impregnation passageway as it contacts the molten thermoplastic polymer.
