Abstract
Provided is a multi-tow carbon fiber spreading and pre-impregnation system, which is used to solve the technical problems of large thickness, high porosity and the like of a prepreg tape product caused by low spread ratio and insufficient pre-impregnation in the production process of existing thermoplastic prepreg tapes. The system includes a filament release module, a filament doubling module, an airflow spreading module, a process deviation correction module, a traction module, a slurry impregnation module, an infrared melting module, a hot-pressing shaping module, a floating roller module, a cutting module, a leftover collecting module, a winding deviation correction module and a winding module which are sequentially arranged along a feeding direction. The filament release module includes at least two filament release assemblies, and carbon fibers are placed on the filament release assemblies.
