Abstract

The invention relates to an apparatus for preparing a continuous filament reinforced thermoplastic resin composite material prepreg tape, which comprises a yarn stand (10), a tension adjusting device (20), an electrostatic eliminating device (30), a preheating oven (40), a tension adjusting device (50), a dual-extruding die head (60), a three-roller dipping device (70), a cooling roll-in device (80) and a traction and winding device (90). The apparatus adopts the staggered dual-extruding die head (60) to pre-dip the continuous filament tape. Compared with the prior art, the apparatus has the advantages that the apparatus is simple, the continuous filament reinforced thermoplastic resin composite material prepreg tape prepared by the apparatus has low cost, the filament is dipped completely and the void ratio is kept to be not higher than 0.2 percent.

Description

technical field [0001] The invention relates to a continuous fiber-reinforced thermoplastic resin composite material prepreg tape, in particular to a preparation device for a continuous fiber-reinforced thermoplastic resin composite material prepreg tape and a method for preparing the prepreg tape using the device. Background technique [0002] Continuous fiber reinforced thermoplastic resin composite prepreg tape has excellent mechanical properties such as high tensile strength, flexural strength / modulus, high and low temperature impact strength, etc., and has the characteristics of relatively low density and recyclability, so in recent years It has been greatly developed, and the corresponding preparation technology has also obtained a major breakthrough. The key to the preparation of the material lies in the dispersion and infiltration of the fibers and the interface bonding between the fibers and the resin. Therefore, the related technologies mainly solve the dispersion ...
