WIPO Patent Application WO/2011/122179

A1

Disclosed is a fiber-reinforced plastic molding that is thin with high rigidity and has excellent sound absorbency and sound insulation. The fiber-reinforced plastic molding (1) is equipped with an open-cell foam material (2) that absorbs sound waves, a hard closed-cell foam material (3) covering the surfaces of the open-cell foam material (2), and a fiber-reinforced plastic (4) that reflects sound waves and is disposed on both sides of the hard closed-cell foam material (3), wherein the open-cell foam material (2) is exposed to the outside through openings (5) formed in the hard closed-cell foam material (3) and the fiber-reinforced plastic (4), and sound waves that enter through the openings (5) are absorbed by the open-cell foam material (2).
