Problems solved by technology

However, during the fiber bundle impregnation process of this type of technology, the fiber bundle plane will not undergo any rotation, and there will be no relative movement between monofilament fibers, and the movement state of the fibers will be simplified, resulting in poor impregnation effect.

Abstract

The invention discloses a forming device for a thermoplastic composite. The forming device comprises an impregnation module arranged in an impregnation cavity. The impregnation module sequentially comprises a front impregnation roller set, a middle impregnation roller set and a rear impregnation roller set, wherein the front impregnation roller set is used for enabling fiber bundles to move in a transverse plane manner, the middle impregnation roller set is used for enabling the fiber bundles to move in a vertical plane manner, and the rear impregnation roller set is used for enabling the fiber bundles to move in the transverse plane manner. By means of the forming device, the fiber bundle planes can achieve reciprocating rotating motion in the impregnation process, relative motion is generated between monofilament fibers, and therefore effective impregnation to the fiber bundles is achieved.

Description

technical field [0001] The invention relates to the technical field of thermoplastic composite materials, in particular to a molding device for thermoplastic composite materials. Background technique [0002] Thermoplastic resin-based composites are fiber-reinforced materials based on thermoplastic resins, mainly including long-fiber-reinforced pellets, continuous-fiber-reinforced prepreg tapes, and short-fiber-reinforced thermoplastic resins. Compared with ordinary short fiber reinforced thermoplastic resins, it has more outstanding mechanical properties, heat resistance, warpage resistance, dimensional stability, etc., so it can manufacture products with excellent mechanical properties, such as auto parts, electronic devices , chemical components, etc. [0003] The quality of thermoplastic composite products is good or bad, one of the more important links is fiber impregnation, fiber impregnation effect and fiber bundle thickness and monofilament dispersion uniformity dur...
