Embodiment 1

[0032](1) Unwinding device 1: It mainly includes a creel or an unwinding roller. The continuous fiber fabric with a fixed width is placed on the roller of the creel or the unwinding roller. The roller is a metal circular roller.

[0033] (2) Tension control device: The continuous fiber fabric on the creel or unwinding roller enters the tension control device, which is composed of three tension rollers 2 at a certain angle, and the three rollers are evenly positioned according to the three vertices of an equilateral triangle. Arrangement can better control the tension of the composite tape during the winding process. The tension roller 2 can also arrange and advance the drawn continuous fiber reinforced fabric evenly and smoothly. The tension roller 2 here can not only increase the tension of the continuous fiber reinforced fabric during the reproduction process, but also allow it to be evenly arranged in parallel, reduce the horizontal gap between the fiber tows (continuous fi...

Abstract

The invention relates to a device for producing continuous fiber fabric reinforced thermoplastic polyurethane. The device comprises an unwinding device, a tension control device, a static eliminating device, a preheating device, a dipping device, a heating curing device, a cooling device and a winding device in sequence, wherein after passing through the unwinding device, the tension control device, the static eliminating device and the preheating device in sequence, a continuous fiber reinforced fabric is poured with a thermoplastic polyurethane elastomer solution in the dipping device to generate a composite fiber fabric with polyurethane resin, then the composite fiber fabric with polyurethane resin is prepared into the continuous fiber fabric reinforced thermoplastic polyurethane through the heating curing device and the cooling device, and the continuous fiber fabric reinforced thermoplastic polyurethane winds the winding device. Compared with the prior art, the production device is simple in structure and easy to operate; the fiber content in the produced continuous fiber fabric reinforced thermoplastic polyurethane is high; meanwhile, the complete wetting of fibers and resin can be ensured.

Description

technical field [0001] The invention relates to the field of production equipment for polymer composite materials, in particular to equipment for producing continuous fiber fabric reinforced thermoplastic polyurethane. Background technique [0002] Due to its excellent mechanical properties, fiber-reinforced thermoplastic composites have been used more and more in daily life in recent years, such as home appliances, military composites, automobiles, etc. The thermoplastic-based composite material has high mechanical strength, can replace metals such as steel, is light in weight, can be reused, and has excellent environmental protection. [0003] However, the high melt viscosity of thermoplastic resin is an important factor limiting its development. The high melt viscosity makes the wetting effect with the fiber very poor, and it is easy to produce dry yarn. In order to increase the infiltration effect of resin and fiber fabric, most of them will use thermoplastic resin pow...
