Abstract

The invention relates to a continuous ultra-thin unidirectional tape prepreg machine based on thermoplastic resin prepreg, comprising a fiber cylinder for placing carbon fibers, and a fiber traction device connected with the fiber cylinder for guiding the carbon fibers forward; The fiber splitting device is connected with the fiber pulling device and is used to expand the carbon fiber to a preset thickness; the dipping tank device is connected with the fiber splitting device and is used to impregnate the carbon fiber with resin; the first detection device, preheating box, drying Dry box, driving device, high temperature box, hot pressing device and main control unit. The main control unit of the present invention adjusts the temperature of the preheating box according to the carbon fiber uniformity obtained by the first detection device, and at the same time adjusts the pressure of the hot pressing device according to the thickness of the carbon fiber obtained by the first detection device, so that the produced prepreg The thickness of the material meets the preset standard.

Description

technical field [0001] The invention relates to the field of preparing prepregs, in particular to a continuous ultra-thin unidirectional belt prepreg machine based on thermoplastic resin prepregs. Background technique [0002] Prepreg is a resin matrix impregnated with continuous fibers or fabrics under strictly controlled conditions to make a composition of resin matrix and reinforcement, which is an intermediate material for the manufacture of composite materials. There are two kinds of preparation methods of prepreg: dry method and wet method. Dry method is divided into powder method and hot melt resin method (the latter is also called hot melt method). Powder prepreg refers to a composite in which the resin powder is attached to the fiber, and after partial melting, the resin is discontinuous and the fiber is not fully saturated with the resin. In the application field of composite materials, the lay-up method is often used to convert prepregs into structural parts. T...
