Title: METHOD FOR PRODUCING COMPOSITE MATERIAL STRUCTURE
Abstract:
In this method for producing a composite material structure, a linear seal member having an edge is inserted in a seal groove in at least one side surface of adjacent segments. A lip section is provided to the upper part of the seal of the seal member, and at least the tip of said lip section protrudes on the exterior of the seal groove when the seal member is inserted in the seal groove. In addition, either a cavity is formed in the interior of the lip section or a recess is formed in at least the bottom part of the seal. When assembling a plurality of segments into a single structure, the side surfaces of adjacent segments are joined to each other, the seal member provided to one of the segments is pressed and crushed in the cross-sectional direction by the side surface of the other segment, and the area between the segments is thereby sealed. As a result, good sealing is achieved between adjacent segments of a mold and it is possible to minimize or avoid complications in the production process.
