Abstract

The invention provides a hot press molding device for a carbon fiber enhanced polyether-ether-ketone (PEEK) composite board. The hot press molding device comprises a hydraulic machine, a molding die and a vacuum system. According to the device, a heating unit is separated from the hydraulic machine, and a heating pipe is used for heating the die to achieve a high temperature hot pressing function; by carrying out hot press molding in a vacuum environment, the content of bubbles in resin can be greatly reduced, and the test piece surface smoothness and workpiece performances are improved; a cooling unit is arranged in the die, and cooling speed is regulated by regulating the flow and temperature of high pressure cold air, so as to control the crystallinity of matrix resin and realize flexible selection between high strength and high toughness. Correspondingly, the invention also provides a hot press molding method for the carbon fiber enhanced polyether-ether-ketone (PEEK) composite board. A carbon fiber enhanced polyether-ether-ketone (PEEK) composite board produced by adopting the device and the method disclosed by the invention through hot press molding is simple in production equipment and solves the problems that material internal porosity is large, resin impregnation fiber is insufficient, test piece performance is insufficient, molding cycle is long and the like during production of polyether-ether-ketone resin with high melting point and high viscosity.
