A continuous melt impregnation apparatus for glass fiber reinforced thermoplastic resin and a method of manufacturing

Abstract

The present application relates to a kind of continuous glass fiber reinforced thermoplastic resin melt impregnation equipment, including impregnation shell, glass fiber heating pre-dispersion area is arranged in the impregnation shell, resin impregnation area and resin redispersion area are connected and communicated, and fiber channel for passing through long fiber bundle in resin impregnation area and resin redispersion area is arranged wave-shaped.The impregnation shell is arranged with a self resin impregnation area entrance, horizontally through resin impregnation area and resin redispersion area, and the communication flow channel connected with discharge port die, the communication flow channel is located between the wave peak and wave trough of wave-shaped fiber channel.The present application is by being arranged in resin impregnation area and resin redispersion area communication flow channel, after entering resin impregnation area, resin melt is automatically shunted, wherein a part of long fiber bundle side is infiltrated, and the other part advances along the communication flow channel and again impacts the same side of long fiber bundle with the angle different from before, promotes resin disturbance and realizes re-infiltration penetration.
