The invention relates to a quick manufacturing process for carbon fiber reinforced paste resin. The quick manufacturing process mainly comprises the following steps of: processing a PS foam board, sequentially performing extrusion-coating on an epoxy paste resin material, a carbon deposition fiber reinforced resin layer and adhesive support, removing the PS foam board to support, position and process a surface, which is separated from the PS foam mould, of the epoxy paste resin material, and performing surface treatment on the processed surface to obtain a final workpiece. Automobile carts manufactured by the quick manufacturing process are short in processing time and are high in processing precision, and processed parts can be modified by many times to meet requirements of a developer. Compared with conventional injection-molding and stamping, the quick manufacturing process greatly shortens development time, reduces cost, and meets physical properties needed, and therefore, a quickand precise process route is provided for developing and repairing automobile part products.
