Laminated plate and method for manufacturing laminated plate

Abstract

The present invention provides a laminated plate capable of not only achieving a reduced weight and an increased rigidity but also improving a sound absorbing performance, and a method for manufacturing the same. A laminated plate (1) is supposed to include a core layer (2) including a plate-shaped paper honeycomb structure (4) and a pair of fiber reinforcement layers (3) sandwiching the paper honeycomb structure (4) from both sides in a thickness direction and integrated with the paper honeycomb structure 4. The through-holes (5) of the paper honeycomb structure (4) are filled with a foam resin (6), and the core layer (2) is made up of the paper honeycomb structure 4 and the foam resin (6) filled in the through-holes (5). When the foam resin (6) is filled in the through-holes (5) of the paper honeycomb structure (4), the foam resin plate (6A) is pushed into the through-holes (5) as a filling material by utilizing a compression force of a mold (11).
