Alternatively, the equivalent diameter of the honeycomb holes 111 of the honeycomb core 11 adjacent to the second reinforcing layer 14 ranges from 10mm to 20 mm. Further, the equivalent diameter of the honeycomb holes 111 of the honeycomb core 11 adjacent to the second reinforcing layer 14 ranges from 12mm to 15 mm. For example, the equivalent diameter of the cell holes 111 of the honeycomb core 11 adjacent to the first reinforcing layer 13 is 12.5mm, 13mm, or 14 mm.

For example, the difference d between the equivalent diameters of the cell holes 111 of the adjacent two cell cores 11 is 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, or 9 mm. Through the experimental verification of the inventor, the difference of the equivalent diameters of the honeycomb holes 111 of the two adjacent honeycomb cores 11 is too small, and the impact resistance of the honeycomb panel 1 is weakened; the difference value of the equivalent diameter of the honeycomb holes 111 of two adjacent honeycomb cores 11 is too large, the noise reduction effect of the honeycomb plate 1 is weakened, and the difference value d of the equivalent diameter of the honeycomb holes 111 of two adjacent honeycomb cores 11 is limited to 2-10 mm, so that the impact resistance of the honeycomb plate 1 can be ensured, and the noise reduction effect of the honeycomb plate 1 can be ensured.
Alternatively, the equivalent diameters of the different honeycomb holes 111 in the same honeycomb core 11 may be the same or different. Alternatively, the equivalent diameters of the different honeycomb holes 111 in the same honeycomb core 11 are the same, thereby facilitating the manufacturing. When the equivalent diameters of the cell holes 111 of the same cell core 11 are the same, the difference between the equivalent diameters of the cell holes 111 of two adjacent cell cores 11 is the difference between the equivalent diameters of the corresponding cell holes 111. When the equivalent diameters of the cell holes 111 of the same cell core 11 are different, the difference between the equivalent diameters of the cell holes 111 of two adjacent cell cores 11 may be the difference between the average equivalent diameters of the cell holes 111 of two adjacent cell cores 11, that is, the average value of the equivalent diameters of the plurality of cell holes 111 of each cell core 11 is the average equivalent diameter of the cell core 11, and the difference between the average equivalent diameters of the cell holes 111 of two adjacent cell cores 11 is d.

Specifically, the micro-foamed thermoplastic resin member has micro-pores formed on the surface thereof, which is more advantageous for improving the noise reduction effect of the honeycomb panel 1. In addition, since the density of the thermoplastic resin is low and the number of the micropores is increased, the density of the honeycomb panel 1 is low, and a better light weight effect can be obtained in use.
In some embodiments of the invention, the wall thickness of the honeycomb cells 111 may range from 0.8mm to 1.2 mm. For example, the honeycomb holes 111 have a wall thickness of 0.9mm, 1.0mm, or 1.1 mm. Thereby, it is advantageous to ensure the structural strength of the honeycomb panel 1. Further, with the honeycomb core 11 of the microcellular foamed thermoplastic resin member, it is also possible to avoid the cells from breaking the honeycomb structure or causing a reduction in the compression resistance of the honeycomb core 11 during the molding of the honeycomb core 11.
