Abstract
Provided is a panel capable of suppressing delamination of a base material and a surface material. The present invention provides a panel comprising a base material and a surface material, wherein the surface material is fixed inside a recessed part provided on the base material.
Claims11
A panel comprising a base material and a surface material, wherein the surface material is fixed inside a recessed part provided on the base material.
5-7. (canceled)
A panel comprising a base material and a surface material, wherein:
- the core material comprises a base material and a reinforcing material,
- the reinforcing material is configured of a material having strength higher than that of the base material, and
- each of the base material and the reinforcing material is adhered to the surface material.
A panel comprising a core material, a first surface material, and a second surface material, wherein:
- the core material is interposed between the first surface material and the second surface material,
- a thickness of the core material is 15 to 25 mm,
- the first surface material and the second surface material are adhered to the core material,
- a first surface material strength index is defined by (a Young's modulus of the first surface material [GPa])×(a thickness of the first surface material [mm])2,
- a second surface material strength index is defined by (a Young's modulus of the second surface material [GPa])×(a thickness of the second surface material [mm])2,
- an average surface material strength index is defined as an average value of the first surface material strength index and the second surface material strength index, and
- a panel strength index defined by (the average surface material strength index)×(10% compressive stress of the core material [MPa]) is 0.7 or greater.
