Abstract
A mold for a composite material structure includes: a plurality of segments including side surfaces configured to be coupled to each other, seal grooves being provided on at least one of the adjacent side surfaces; a pair of annular holding members configured to fix both respective end surfaces of the segments to keep them as a single structure; and seal members configured to seal between the segments when the side surfaces are coupled with the seal member inserted in the seal groove. Each seal member is formed in a line shape having ends. A lip portion is provided at a seal upper portion of the member. The seal member is hollow or includes a concave portion on at least a seal bottom portion thereof. With this, complication of manufacture of a hollow composite material structure can be suppressed or avoided while realizing a satisfactory sealed state between the adjacent segments.
