Production equipment and production process of thermoplastic continuous carbon fiber unidirectional tape

Abstract

The invention discloses a production equipment for thermoplastic continuous carbon fiber unidirectional tape, which comprises a fiber unwinding device, a yarn spreading mechanism, a dipping device, a flattening mechanism, a cooling plate, a trimming device, a traction roller, two waste Side winders, cross cutters and winders. The fiber unwinding device includes a frame, two sets of bobbins, two sets of yarn guide rollers, two sets of yarn guide porcelain eyes, two sets of transition yarn rollers and four moving wheels; Roller, reed door, splitting tractor, spreading transition roll, vibrating roll, two tension driving rolls, two tension floating rolls and second guide roll; impregnation device includes impregnation die head, discharge die head and extruder ;The flattening mechanism includes a pair of sizing rollers, a pair of front cooling rollers and a pair of rear cooling rollers arranged in sequence; two waste edge winders are respectively arranged on both sides in front of the traction roller; the winding device includes interchangeable The first winder and the second winder; the invention effectively guarantees the production quality of the fiber unidirectional belt.

Description

technical field [0001] The invention relates to a production equipment and a production process of a thermoplastic continuous carbon fiber unidirectional tape. Background technique [0002] Continuous Fiber Reinforced Thermoplastic Composite Materials CFRTP (Continuous Fiber ReinforcedThermoplastic Composites Panels) This series of products use a unique process to produce products with high strength, high modulus, high impact resistance, fatigue resistance, good thermal stability, corrosion resistance, low Excellent properties such as warping and environmental protection and recyclability. Continuous fiber reinforced thermoplastic composites are often prepared by high temperature impregnation. The specific method is: the continuous fiber yarn is guided into an impregnation die head with a special structure under tension traction by the unwinding device, and a special extruder is used to melt the thermoplastic plastic into a liquid resin flow under high temperature and high ...
