Abstract

The invention relates to a resin base composite material, in particular to a device for preparing carbon fiber thermoplastic dipping strips by water base powder dipping and a method thereof. The device comprises a wire releasing device, a carbon fiber surface treatment device, a water base powder suspension dipping device, a contact drying device, a fusion dipping molding device, a calendering device and a traction device in sequence; and the water base powder suspension dipping device comprises a pulp dipping device, a liquid storage device and a liquid feeding device. Compared with dry powder dipping, the method reduces the explosion danger when dust meeting with fire, and prevents the dust pollution in the machining process. Compared with a melting method, the method reduces the machining temperature to prevent the resin aging caused by long-time retention of melts in a dipping cavity.

Description

technical field [0001] The invention relates to resin-based composite materials, in particular to a device and method for preparing carbon fiber thermoplastic impregnated tapes by impregnating water-based powder. Background technique [0002] Continuous fiber reinforced thermoplastic resin matrix composites are a new type of structural material with high strength, high modulus, low density, corrosion resistance, and easy processing, especially continuous carbon fiber reinforced high-performance thermoplastic composites. Automobiles, rail transit, oil and gas and other fields have shown good application prospects. The above-mentioned high-performance thermoplastic composite materials refer to high-performance special engineering plastics, such as polyether ketone ketone, polyether ether ketone, polyphenylene sulfide, and the like. [0003] The preparation processes of continuous fiber reinforced thermoplastic prepreg tapes include powder impregnation, melt pultrusion impregn...
