Patent number: 9050748Abstract: In manufacturing composite material by curing fluid, strength deterioration of the composite material due to repair before the fluid is cured is reduced. A suction hole is formed in a bag film (3) for sealing a space for fibers being impregnated with resin, after start of impregnation. The suction hole is covered by a plate (56) with holes (57). The resin is sucked from the space through the plate (56). According to such composite material manufacturing method, a defect, which occurs during fibers are impregnated with resin, can be repaired before the resin is cured without causing disorder and damage in the fibers. In a composite material formed from one repaired in the above way, the repaired portion is strong, namely, there is no strength deterioration due to repair after curing, and thus, the material is preferred as compared with a composite material which is repaired after resin is cured.Type: GrantFiled: October 31, 2012Date of Patent: June 9, 2015Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Masayuki Kanemasu, Shigeru Nishiyama, Hideki Horizono
