The invention provides a carbon
fiber polyamide prepreg preparation device and a preparation method thereof and solves the technical problems that existing equipment has the problems of complex steps, environmental
pollution and low heating and producing efficiency, and resin and carbon
fiber are uneven in adhesion and further has weaker combining capacity and larger
porosity and the like. The carbon
fiber polyamide prepreg preparation device is sequentially provided with a carbon fiber belt wheel, a first tension wheel, a first
infrared heater, a first U-shaped molten resin spray head, a second
infrared heater, a second U-shaped molten resin spray head, a second tension wheel, a third
infrared heater, a first heating roller, a fourth
infrared heater, a second heating roller, a third tension wheel, a fourth tension wheel, a cooling roller, a press
machine, a conveyer belt and a transmission roller from left to right. Furthermore, the invention provides carbon fiber pretreatment, molten resin preparation and carbon fiber traction and fixation and the like. The carbon fiber
polyamide prepreg preparation method can be widely applied to the field of carbon fiber resin based compositematerials.
