Specific names of the structures in fig. 1-5 are: the novel honeycomb core material comprises a base material 1, honeycomb core materials 1-1, glass fiber plates 1-2, hexagonal sandwiches 1-3, arc-shaped edges 2, needle-punched non-woven fabrics 3, velvet needle-punched non-woven fabrics 4, a hot melt adhesive layer 5 and a handle box 6.
Detailed Description
Referring to fig. 1 to 3, the specific structure of the present embodiment is: a car trunk carpet comprises a base material 1, wherein the base material 1 is a continuous glass fiber reinforced thermoplastic polypropylene honeycomb plate, the base material 1 comprises a honeycomb core material 1-1 and two layers of glass fiber plates 1-2, the two layers of glass fiber plates are respectively and fixedly connected to the top and the bottom of the honeycomb core material 1-1, the side length of a hexagonal sandwich 1-3 in the honeycomb core material 1-1 is 4.2mm-6.3mm, and the main body thickness of the honeycomb core material 1-1 or the hexagonal sandwich 1-3 is 8mm-40 mm; the thickness of the glass fiber plate 1-2 is 0.18mm-0.5 mm; the substrate 1 is provided with an arc-shaped edge 2, the arc-shaped edge 2 is bent inwards, the thickness of the arc-shaped edge 2 is 7.75mm-39.15mm, and the length of the arc-shaped edge 2 is 20-30 mm; the base material 1 and the 2 bottom fixedly connected with acupuncture non-woven fabrics 3 in arc edge, 3 thickness of acupuncture non-woven fabrics are 0.15 mm-0.2mm, 1 upper portion of base material and 2 peripheries in arc edge all have pile needle non-woven fabrics 4 through hot melt adhesive fixedly connected with, 3 lower parts of acupuncture non-woven fabrics are arranged in to the pile needle non-woven fabrics 4 in arc edge 2 bottom.
The thickness of the hot melt adhesive layer 5 between the upper part of the substrate 1, the periphery of the arc-shaped edge 2 and the wool needle punched non-woven fabric is 0.05 mm.
The manufacturing method of the utility model is as follows:
honeycomb panel one side itself is with acupuncture non-woven fabrics 3, heat the honeycomb panel in the heating furnace, then with the mould with peripheral region compress thinly, the banding, the preparation is arc edge 2, the honeycomb panel covers a fine hair acupuncture non-woven fabrics 3 with the hot melt adhesive after through the mould shaping, then with the acupuncture non-woven fabrics 4 of fine hair turn over bordure, the acupuncture non-woven fabrics 4 of positive fine hair turn over increase peripheral aesthetic property and the fastness of whole product after borduring, assemble handle box 6 at last.
The principle of the utility model is as follows:
(1) the continuous glass fiber and PP resin impregnated surface layer realizes the impact resistance and planting performance like plastic replacing steel, and can disperse and bear external force from all sides due to the arrangement of multiple wall surfaces and a series of continuous honeycomb-shaped reticular structures, so that the resistance of the honeycomb structure to extrusion force is much higher than that of any round or square, in addition, the honeycomb core material used in the application only weighs 80 g/square meter area per millimeter of thickness, and the weight of the trunk carpet is reduced to the maximum extent.
(2) The hollow honeycomb structure can effectively absorb external vibration and convert the external vibration into deformation energy of the core material, and then slowly release the deformation energy, in addition, after sound waves enter the honeycomb body, the vibration of air and materials can be caused, and due to friction resistance and viscous resistance, a part of sound energy is converted into heat energy to be dissipated, so that the silencing effect is achieved.
