Embodiment 1

[0059] A method for preparing a continuous glass fiber reinforced polypropylene prepreg line, comprising the following steps:

[0060] (1) The continuous fiber roll 11 is installed on the spindle support 13 of the spinning frame 10, and the continuous fiber roll is carefully pulled through the guide hole installed on the creel 10, and the fiber drawn out through the guide hole is passed through the tension device 20. The thread discharge port 21 makes the fibers parallel and evenly arranged to avoid crossing and abrasion between the fibers. Then the continuous fiber bundles 12 arranged in parallel pass through the tension adjustment roller 22, apply a certain tension to the fibers to ensure the preliminary dispersion of the fibers, and eliminate the static electricity generated by the static elimination device 30; the continuous fiber roll 11 is a continuous glass fiber roll.

[0061] The spinning frame 10 is provided with a horizontally rotating spindle support 13, and the sp...

Embodiment 2

[0072] A preparation method for continuous aramid fiber reinforced polyethylene terephthalate prepreg line, comprising the following steps:

[0073] (1) The continuous fiber roll 11 is installed on the spindle support 13 of the spinning frame 10, and the continuous fiber roll is carefully pulled through the guide hole installed on the creel 10, and the fiber drawn out through the guide hole is passed through the tension device 20. The thread discharge port 21 makes the fibers parallel and evenly arranged to avoid crossing and abrasion between the fibers. Then the continuous fiber bundles 12 arranged in parallel pass through the tension adjustment roller 22, apply a certain tension to the fibers to ensure the initial dispersion of the fibers, and eliminate the static electricity generated by the static elimination device 30; the continuous fiber roll 11 is a continuous aramid fiber roll.

Abstract

The invention discloses a continuous fiber-reinforced thermoplastic resin prepreg thread. The continuous fiber-reinforced thermoplastic resin prepreg thread is prepared from, by weight, 50 to 65 parts of continuous fibers, 30 to 45 parts of thermoplastic resin, 0.2 to 0.6 part of an anti-oxidant, 0.5 to 1 part of an anti-ultraviolet light stabilizing agent and 3 to 5 parts of a grafting agent. The invention also discloses a preparation method for the continuous fiber-reinforced thermoplastic resin prepreg thread and an apparatus used therein. According to the invention, a raw material formula is changed and adjusted; the prepreg thread is prepared from a produced prepreg tape; the produced prepreg thread can be used for braiding of a three-dimensional braided fabric via a three dimensional braiding device; and the eventual purposes of improving interlayer bonding and enhancing the mechanical properties of a product are achieved.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and relates to a continuous fiber-reinforced thermoplastic resin prepreg line, a preparation method and a device used. Background technique [0002] Continuous fiber reinforced thermoplastic composites exhibit high mechanical properties due to the orderly arrangement of continuous fibers in the matrix, and it is also one of the focuses of research at home and abroad in recent years. Making continuous fiber-reinforced thermoplastic prepreg tape, and then hot pressing the continuous fiber-reinforced thermoplastic prepreg tape into products is currently a commonly used method for making continuous fiber-reinforced thermoplastic composite materials. Chinese patent CN 129465A discloses a method for continuous fiber-reinforced thermoplastic resin prepreg, which uses pre-dispersed mixed fiber yarns to manufacture continuous fiber-reinforced thermoplastic prepreg by heating, melting and rolli...
