Abstract

A panel structure includes: a sheet-shaped core member having a thermoplastic property and provided with a plurality of protruding portions in at least one surface; a sheet-shaped faceplate having a thermoplastic property and disposed on the plurality of protruding portions; and a fusing portion which is selectively formed between the faceplate and the plurality of protruding portions and which bonds the core member and the faceplate to each other.

First claim

What is claimed is:

1 . A panel structure comprising:
a sheet-shaped core member that has a thermoplastic property and includes a plurality of protruding portions on at least one surface; a sheet-shaped faceplate that is disposed on the plurality of protruding portions and has a thermoplastic property; and a fusing portion that is selectively formed between the faceplate and the plurality of protruding portions and joins the core member and the faceplate to each other.

2 . The panel structure according to claim 1 ,
wherein the protruding portion is formed on both surfaces of the core member.

3 . The panel structure according to claim 1 ,
wherein the protruding portion is a continuous corrugated portion that is formed on the surface of the core member.

4 . The panel structure according to claim 3 ,
wherein the corrugated portion has a slit or a groove in at least one of a peak portion or a valley portion along a direction orthogonal to a direction of shaping the peak portion or the valley portion.

5 . The panel structure according to claim 1 , further comprising a metal thin film that is formed on at least one surface of the faceplate.

6 . The panel structure according to claim 1 , further comprising a filling member that is disposed in a space between the core member and the faceplate.

7 . The panel structure according to claim 6 ,
wherein the filling member is a latent heat storage material.

8 . The panel structure according to claim 1 ,
wherein at least one of the core member or the faceplate contains a latent heat storage material.

9 . The panel structure according to claim 1 , wherein a plurality of the core members are provided.

10 . The panel structure according to claim 1 , further comprising a flow path through which a fluid flows between the core member and the faceplate.

11 . The panel structure according to claim 10 ,
wherein the fluid is a liquid or a gas.

12 . The panel structure according to claim 1 , further comprising a hole portion that is selectively formed in at least one of the core member or the faceplate.

13 . The panel structure according to claim 1 ,
wherein the faceplate is formed of a porous resin or a resin including a non-woven carbon fiber.

14 . The panel structure according to claim 1 , further comprising a sound absorbing member that is disposed between the core member and the faceplate.

15 . The panel structure according to claim 1 , further comprising an extinguishant that fills in between the core member and the faceplate.

16 . The panel structure according to claim 1 , wherein at least one of the core member or the faceplate contains an extinguishant.
