Impregnating equipment for producing high-temperature-resisting thermoplasticity composite material unidirectional prepreg tape

Abstract

The invention provides impregnating equipment for producing high-temperature-resisting thermoplasticity composite material unidirectional prepreg tape. The equipment comprises a yarn discharging device, a yarn binding hole disc, a yarn spreading device, a slurry impregnation device, a pre-baking device, an isolating membrane unwinding and winding device, a hot melt impregnation device, a molding device, a cooling and press polish device, a slitting device, a tension detection device and a spiral winding device. The yarn discharging device, the yarn spreading device, the slurry impregnation device, the pre-baking device, the isolating membrane unwinding and winding device, the hot melt impregnation device, the molding device, the cooling and press polish device, the slitting device, the tension detection device and the spiral winding device are sequentially arranged. The resin content of prepreg prepared through the impregnating equipment for the prepreg tape is uniform and stable, and the hot melt effect is promoted. The resin content of the prepreg tape can be effectively controlled, and the high-temperature-resisting thermoplasticity composite material unidirectional prepreg tape which is uniform and low in porosity is prepared.

Description

technical field [0001] The invention relates to the technical field of preparation equipment for polymer composite materials, in particular to an impregnation equipment for producing unidirectional prepreg tapes of high-temperature-resistant thermoplastic composite materials. Background technique [0002] Thermoplastic composite unidirectional prepreg tape has good mechanical properties (high tensile strength, high bending strength, high impact strength, high toughness, high fatigue resistance), anti-aging, corrosion resistance, strong designability and Excellent characteristics such as processability, short molding cycle, and environmental friendliness. It is precisely because of the above-mentioned excellent characteristics that thermoplastic composite unidirectional prepreg tapes are more and more used in light traffic rails, aerospace and other fields. However, since the resin matrix used is mostly ordinary engineering plastics such as PP (Polypropylene, polypropylene),...
