Problems solved by technology

This method can produce a fully impregnated continuous fiber reinforced thermoplastic resin composite material prepreg tape, but because the raw material is a pre-manufactured mixed fiber yarn, that is, the thermoplastic resin needs to be melt-spun first, and then mixed with other fibers. Therefore, the manufacturing cost and technical difficulty of the material are relatively high, which does not meet the requirements of low-cost manufacturing of the material

Embodiment 1

[0043] Continuous Glass Fiber Reinforced Polypropylene Prepreg Tape

[0044] Such as figure 1 As shown, the continuous glass fiber roll (PPG company 4588 2400tex) is installed on the spindle 13 of the creel 10, and the fiber is carefully drawn out from the thread guide port on the creel and passed through the thread discharge port 21 of the tension adjustment device to make the fiber Parallel and evenly arranged to avoid mutual crossing and wear between fibers, then the continuous fibers arranged in parallel pass through the tension roller 22, and a certain tension is applied to the fibers to ensure the initial dispersion of the fibers; then the fibers are eliminated by the static elimination device 30. Static electricity, and then the continuous fiber is preheated to 230°C through a preheating oven 40 (infrared oven is used);

[0045] The preheated continuous fiber is led to the twin extrusion dies 61, 62 through the tension regulator 50 for pre-impregnation. A single-screw ...

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 ...
