Title:
COMPOSITE MATERIAL MOLDING DIE AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2012/002355
Kind Code:
A1
Abstract:
Disclosed is a method for producing a composite material molding die capable of producing the die regardless of the size of an autoclave. A method for producing a composite material molding die is provided with a process for creating constituent members (1a, 1b), the process comprising a step for forming an upper surface (3) of a core material (2) to a shape corresponding to the shape of a molded body, a step for forming steps (5a, 5b) on a side surface (4) of the core material (2) facing another core material (2), a step for laminating an uncured composite material on the surface of the core material (2) and curing the material to form a composite material layer (8), and a step for forming a tapered portion (10) on the composite material layer (8) located on another surface, which is perpendicular to the side surface (4), of the core material (2); a process for coating an adhesive agent on the side surface (4) and connecting the constituent members; a process for laminating the uncured composite material on the tapered portion (10), arranging a heat source (16) on the composite material, and curing the composite material; and a process for polishing the surface of the connected constituent members (1a, 1b).
