RTM RESIN FLOW CONTROL METHOD AND APPARATUS

摘要

PROBLEM TO BE SOLVED: To eliminate the generation of an air sump or the like of molding to eliminate the quality irregularity of a product in an RTM resin flow control method and apparatus. SOLUTION: A fiber substrate 20 is set to the inside of a mold 10 and a resin, of which the pressure and temperature are set, is injected in the mold 10 from a plurality of resin injection ports 11a and 11b by an injection device 2 to impregnate the fiber substrate 20 in the mold 10. This resin flows to flow out of resin outflow ports 12a and 12b. The fiber substrate 20 is taken out of the mold 10 after the resin is cured. A large number of flow sensors 1 are arranged to the inner surface of the mold 10 to detect the leading end of the resin flow and the signals of the flow sensors are inputted to a control unit 3 to be compared with the preset data of the optimum simulation result in a memory device 4 and the pressure and temperature of the injection device 2 are controlled so as to eliminate the differences between the signals and the preset data to allow the resin flow to approach the optimum flow pattern.
