The second through hole on froth bed, the third through-hole being located on lower cover, be provided with boss, described boss in described second through hole
It is provided with fourth hole；Described first through hole, third through-hole, fourth hole consistency from top to bottom form installing hole.
When composite board of the prior art is installed, typically directly installed by fastener or screw, this simple peace
Dress mode can make the installation place fragile structure of sheet material, by the most damaged during big impact.In this utility model, at sandwich foam
Installation site on layer is provided with boss, can be obviously enhanced the intensity of installation region, enables sheet material to resist bigger rushing
Hit power；In the application, installing hole is distributed in the surrounding of sheet material.
As preferably, described upper cover plate is carbon fibre/glass composite bed, concrete, including two-layer carbon fibre layer and layer of glass fiber
Layer, the arrangement mode of the carbon fiber in carbon fibre layer is (0,90), and the arrangement mode of the glass fibre in fiberglass layer is (45 ,-45)；
Described lower cover is resin/carbon fibre/glass composite bed, concrete, including one layer of resin bed, two-layer carbon fibre layer and three layers of glass
Layer, the arrangement mode of resin fibre and carbon fiber is (0,90), the arrangement mode of triplex glass fiber be (45 ,-45)/(0,
90)/(45 ,-45)；Described boss is glass composite block, if including dried layer fiberglass layer, the glass fibre in fiberglass layer
Arrangement mode is that (0,90)/(45 ,-45) are arranged alternately.In this structure, plate construction compound layer by layer has good intensity,
And panel weight is light.
As preferably, described upper cover plate thickness is 1mm, and lower cover thickness is 2.5mm, and sandwich foam layer thickness is 15mm；
While saving material cost, it is possible to meet actual performance needs.
As preferably, the outer surface of described upper cover plate and/or lower cover is coated with aramid fiber layer, improves the resistance to of sheet material
Impact capacity, protects carbon fiber.
Compared with prior art, the composite board during this utility model has the advantages that this utility model uses
Glass, carbon are fine, the composite construction of resin, are sandwiched between sandwich foam layer, intensity height and low cost；And be provided with in mounting structure
Boss, significantly enhances the intensity of installation place, adds the impact resistance of sheet material.
Accompanying drawing explanation
Fig. 1 is the decomposing schematic representation of composite board.
The schematic diagram of the trip bolt that Fig. 2 is used by composite board.
Detailed description of the invention
Below in conjunction with the accompanying drawings and detailed description of the invention, this utility model is further described.
Seeing Fig. 1, a kind of composite board for train, including upper cover plate 1, lower cover 3, described upper cover plate 1 and lower cover 3
Between be provided with sandwich foam layer 2, this composite board is provided with installing hole, and described installing hole includes be located on upper cover plate 1 first
Through hole 11, the second through hole 21 being located on sandwich foam layer 2, the third through-hole 31 be located on lower cover 3, described second through hole 41
In be provided with boss 4, described boss 4 is provided with fourth hole 41；Described first through hole 11, third through-hole 31, fourth hole
41 consistencies from top to bottom form installing hole, can be inserted into screw and composite plate be fixed in this installing hole.
In present embodiment, described upper cover plate 1 is carbon fibre/glass composite bed, concrete, including two-layer carbon fibre layer and one layer
