Abstract
A panel structure includes a plate-like flat panel and a reinforcement panel in which a criterion plate portion and a plurality of truncated conic protrusions protruding from the criterion plate portion are formed. Apex portions of the plurality of truncated conic protrusions in the reinforcement panel are joined to the flat panel by an adhesive.
Claims16
A panel structure comprising:
- a plate-like flat panel;
- and
- a reinforcement panel in which a criterion plate portion and a plurality of truncated conic protrusions protruding from the criterion plate portion are formed,
- wherein apex portions of the plurality of truncated conic protrusions in the reinforcement panel are joined to the flat panel by an adhesive,
- wherein the adhesive includes two kinds of adhesives with different elastic moduli after hardening, and
- wherein, of the two kinds of adhesives, one adhesive is disposed in a plurality of first apex portions between which one or more apex portions intervene among the apex portions of the plurality of truncated conic protrusions and the other adhesive is disposed in second apex portions other than the first apex portions.
