METHOD FOR MOLDING COMPOSITE MATERIAL AND DEVICE FOR MOLDING COMPOSITE MATERIAL

Document Type and Number:

WIPO Patent Application WO/2018/198934

Kind Code:

A1

Abstract:

Provided are a method for molding a composite material and a device for molding a composite material with which the occurrence of a void in a composite material is reduced to enable an improvement in the mechanical characteristics or appearance quality of the composite material. According to a method for manufacturing a composite material (10), a sealing region (270) including a cavity (250) in which a reinforcing base material (11) is arranged and an outer peripheral region (260) communicating with an outer periphery of the cavity is air-tightly sealed by means of a first sealing member (310). Then, an operation of suctioning gas from the outer peripheral region to exhaust the gas inside the sealing region is started, and a resin (12) is injected into a part of the cavity. Next, a molding mold (200) is clamped to press and fill the resin in the cavity, while a space between the cavity and the outer peripheral region is liquid-tightly sealed by means of a second sealing member (320). After that, the operation of suctioning the gas from the outer peripheral region is stopped.
