Embodiment 1

[0066] Install the continuous glass fiber roll (PPG company 45882400tex) on the creel 1, draw the continuous fiber yarn in parallel and evenly and pass through the tension roller 3 to ensure the initial dispersion of the fiber, and the glass fiber forms a unidirectional fiber yarn arranged in parallel and evenly. The static electricity of the glass fiber is eliminated by the static elimination device 4, and then the continuous fiber enters the preheating oven 5, and the temperature set in the oven here is 240°C.

[0067] At the impregnation device, the screw extruder extrudes polypropylene resin (7726 of Yanshan Petrochemical), which has a relatively low viscosity, and pours it onto the glass fiber unidirectional yarn 2 and passes through a double-belt roller press 9, which is in contact with the resin The distance between the upper and lower two steel strips 10 faces is 0.25mm. The temperature of the heating oven is 230°C. After the impregnation is complete, it enters the coo...

Embodiment 2

[0069] Install the continuous carbon fiber roll (Toray T70024K) on the creel 1, draw the continuous carbon fiber yarn in parallel and evenly and pass through the tension roller 3 to ensure the initial dispersion of the fiber, and the glass fiber forms a unidirectional fiber yarn arranged in parallel and evenly. The static eliminator 4 eliminates the static electricity of the glass fiber, and then the continuous fiber enters the preheating oven 5, where the temperature set in the oven is 230°C.

[0070] At the impregnation device, the screw extruder extrudes thermoplastic polyurethane resin (Desmpaopan 372X), extruded and poured onto the carbon fiber unidirectional yarn 2, and passes through a double-belt roller press 9, and the upper and lower steel belts 10 of the roller press are in contact with the resin. The distance between the faces is 0.30mm. The temperature of the heating oven is 220°C. After the impregnation is complete, it enters the cooling and setting device. The g...

Embodiment 3

[0072] Install the continuous natural fiber felt (the natural fiber is ramie fiber provided by Nanjing Xinhe Co., Ltd.) on the unwinding roller 1, carefully lead the continuous natural fiber felt out and pass the tension roller 3 to ensure the smoothness of the fiber surface, pass through the static elimination device 4 Eliminate the static electricity of the glass fiber, and then the continuous fiber enters the preheating oven, where the temperature of the oven is set at 210°C.

[0073] At the impregnation device, the screw extruder extrudes ultra-high molecular weight polyethylene resin with low viscosity, poured onto the continuous natural fiber mat 2 and passes through the double-belt roller press 9, the upper and lower two of the roller press are in contact with the resin The distance between the surfaces of the steel strip 10 is 0.20mm. The temperature of the heating oven is 200°C. After the impregnation is complete, it enters the cooling and setting device. The gap betw...

Abstract

The invention relates to a continuous fiber fabric reinforced thermoplastic resin composite material and a production method thereof. The composite material is produced from continuous fiber through thermoplastic resin melting and impregnating, cooling and molding, with the thickness of 0.20mm-0.35mm, wherein the content of the continuous fiber reinforced fabric is 40wt%-65wt%, the continuous fiber fabric is uniformly spread out and subjected to tension adjustment and static electricity elimination, then enters thermoplastic resin for melting and impregnating, and finally is cooled in a cooling unit and wound and formed to obtain the continuous fiber fabric reinforced thermoplastic resin composite material. Compared with the prior art, the continuous fiber fabric reinforced thermoplastic resin composite material and the production method solve a series of problems caused by too high resin viscosity in the existing thermoplastic resin and fiber reinforcing process, such as complex equipment process, too high equipment cost, not environment-friendly technological operation process, dry gauze easily caused by poor impregnation and the like.

Description

technical field [0001] The invention relates to a prepreg of a continuous fiber reinforced thermoplastic resin composite material, in particular to a continuous fiber fabric reinforced thermoplastic resin composite material and a manufacturing method thereof. Background technique [0002] Composite materials are currently being used more and more in daily life, such as home appliances, electronic appliances, military composite materials, automobiles, etc. However, the market is currently dominated by fiber-reinforced thermosetting composite materials. Thermosetting materials have the characteristics of low viscosity, high strength, good rigidity, excellent weather resistance and heat resistance, are well impregnated with fibers, and are easy to process, so they are widely used. Thermosetting resins are not recyclable, they need to be molded once, and the processing cycle is long, there is a post-curing process, the pollution in the operation process is large, and the impact ...
