A Simulated Coating Rapid Prototyping Wet Molding Process

Abstract

The invention discloses a coating-simulating rapid-forming wet mold pressing technique. Simultaneous conducting of the solidifying forming technique in a pressing machine, the coating-simulating and hot laying technique outside the pressing machine in the next cycle and the treatment technique after last-cycle product cooling is achieved, and final products are protected against buckling deformation. Through coating simulating, the optimum coating position and using quantity are determined, the resin using quantity is effectively reduced, no resin overflows in mold assembly, and mold pollution is avoided; resin coating is conducted outside the pressing machine, site environmental friendliness is achieved, the steps of pre-forming, mold-release agent coating and mold clearing and using of rapid heating and cooling equipment are not needed for the whole technique, and the mold temperature rising-falling time of each forming cycle is omitted, so that the forming time is greatly saved, production efficiency is improved, the temperature rising-and-falling power consuming cost is reduced, the forming environment is improved, the final shortest forming cycle can be controlled to be within 5 min; and the quality of a formed product is good, and the requirements of car parts and the production tendency can be met.

Description

technical field [0001] The invention relates to the technical field of polymer material preparation, in particular to a simulated coating rapid prototyping wet molding process. Background technique [0002] Resin-based composite materials are a type of material with thermosetting or thermoplastic resin as the matrix and carbon fiber, glass fiber, and aramid fiber as reinforcements, especially carbon fiber resin-based composite materials, because of their light weight, good strength, and higher modulus. The advantages of metal have become an indispensable material for realizing the lightweight of automobiles. Typical resin-based composite molding technologies include hand lay-up molding, resin transfer molding (RTM), vacuum-assisted technology, winding technology, autoclave technology, and molding technology. These technologies were originally mainly used in military, aerospace Such as high-end and high-end fields, so it mainly focuses on quality, low molding efficiency and ...
