Panel
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.
1 . A panel comprising a base material and a surface material, wherein the surface material is fixed, via an adhesive layer composed of an adhesive, inside a recessed part provided on the base material,
the base material is a bead foam molded body obtained by bead foam molding, or a foamed or non-foamed sheet molded body composed of a polyolefin and obtained by imparting an uneven shape to a single foamed or non-foamed resin sheet.
2 . The panel of claim 1 , wherein the base material and the surface material are covered with a skin material.
3 . The panel of claim 1 , wherein a width of a periphery between an edge of the recessed part and a side end of the base material is 1 to 20 mm.
4 . The panel of claim 1 , wherein S/T 1 is 0.8 or less, where S represents a step difference between an edge of the recessed part and an edge of the surface material, and T 1 represents a thickness of the surface material.
5 . A panel comprising a core 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,
each of the base material and the reinforcing material is adhered to the surface material,
the reinforcing material comprises a column part and a flange part,
the flange part is provided at one end or both ends of the column part, and
the flange part is adhered to the surface material.
6 . 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.
7 . The panel of claim 6 , wherein the panel strength index is 5.0 or less.
8 . The panel of claim 6 , wherein an areal density of the panel is 3000 g/m 2 or lower.
9 . The panel of claim 1 , wherein the base material is a bead foam molded body obtained by bead foam molding.
10 . The panel of claim 1 , wherein the base material is a foamed sheet molded body composed of a polyolefin and obtained by imparting an uneven shape to a single foamed resin sheet.
11 . The panel of claim 1 , wherein the base material is a non-foamed sheet molded body composed of a polyolefin and obtained by imparting an uneven shape to a single non-foamed resin sheet.
