Problems solved by technology

However, this process is time-consuming and labor-intensive, and the impregnation efficiency is low
[0005] In addition, the current impregnating rollers are generally cylindrical in structure, which has little shearing effect on the resin matrix during actual use, which is not conducive to the impregnation of fiber bundles.
Moreover, during the traction process of the fiber bundle, the movement in the direction of the fiber length is relatively simple, which is not conducive to the effective impregnation of the fiber bundle.

Abstract

The invention discloses an elliptical immersion device for continuous fiber multi-motion state. The elliptical immersion device comprises an immersion cavity; the immersion cavity is internally provided with a plurality of elliptical immersion rollers allowing a plurality of fiber bundles to be wound on in sequence; and any two adjacent ellipse immersion rollers are arranged high and low. The immersion rollers can be driven by movement of the fiber bundles without driving of a power source, during immersion, the immersion rollers shear resin matrixes on the one hand, thus the viscosity of theresin matrixes is lowered, on the other hand, the fiber bundles are driven to move in the longitudinal direction, a reciprocating motion in the non-fiber orientation direction is produced, relative displacement between fibers and the resin matrixes is increased, and effective immersion of the fiber bundles is achieved.

Description

technical field [0001] The invention relates to the technical field of thermoplastic composite materials, in particular to an ellipse impregnation device in a continuous fiber multi-movement state. 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 disper...
