Title:
METHOD FOR MANUFACTURING STRUCTURE USING COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2020/071016
Kind Code:
A1
Abstract:
This method for manufacturing a structure using a composite material includes: a tapering step for forming a first tapered surface (6c) on a first stiffener (6) that is in an uncured state; a bending step for bending the stiffener such that a second surface (6b) is on the inner side; an arranging step for arranging the first stiffener (6) and a skin (2) at prescribed positions; a vacuum suctioning step for vacuum suctioning the first stiffener (6) and the skin (2); and a bonding step for curing the first stiffener (6) to bond the first stiffener (6) and the skin (2). In the tapering step, the tapering is performed such that the angle formed between the first tapered surface (6c) and the second surface (6b) is an acute angle. In the vacuum suctioning step, the vacuum suctioning is performed such that the first tapered surface (6c) is brought into contact with the skin (2) while maintaining contact between the first surface (6a) and the skin (2), and such that the first stiffener (6) is deformed so that a second tapered surface (6d) is formed on the second surface (6b).
