Abstract
The utility model relates to the technical field of artificial boards, in particular to a carbon fiber reinforced poplar composite board, which comprises the following components: 1) using a poplar veneer as a surface plate layer; 2) the poplar laminated veneer lumber is vertically arranged as a core board layer; 3) using a poplar veneer as a bottom plate layer; 4) and the unidirectional carbon fiber cloth is used as a reinforcing layer. The carbon fiber reinforced poplar composite board has the advantages of reasonable structure, good dimensional stability, capability of being used as a large-size board, difficulty in deformation and long service life. The single-face composite carbon fiber cloth improves the defect that fast-growing poplar wood is low in strength, reduces the using amount of bottom poplar wood, has waterproof and ant-proof functions simultaneously due to the fact that poplar wood veneers are arranged on the surface, has price advantages and raw material advantages in actual production due to the fact that the fast-growing poplar wood with low price is used as raw materials, can be used as furniture and a carriage bottom plate, and is a novel carbon fiber reinforced poplar composite board.
Description
The technical field is as follows:
the utility model relates to the technical field of artificial boards, in particular to a carbon fiber reinforced poplar composite board.
Background art:
traditional artificial boards such as plywood and fiberboard are too big in breadth, and are easy to deform and bend in the width direction in the use process, and the vertical core board middle layer adopts the vertical arrangement of laminated veneer lumber, so that the internal stress structure of the board core is changed, and the stability and the service life of the board are improved. The core board of the utility model refers to the vertical core board, adopts the poplar laminated veneer lumber which is vertically arranged, improves the defect of easy deformation of the traditional artificial board, has high strength, high stability and high flatness, adopts the fast-growing poplar as the raw material, has wide source and low price, and improves the use value of the fast-growing poplar.
The composite material of the poplar laminated veneer lumber and the carbon fiber improves the defect of insufficient strength of the poplar, improves the strength of the board, improves the dimensional stability of the board, endows the board with the functions of water resistance and termite resistance, and can be used as furniture, indoor decoration materials and carriage bottom plate materials.
The utility model content is as follows:
the utility model provides a carbon fiber reinforcement poplar wood composite sheet which characterized in that: the carbon fiber reinforced poplar composite board is formed by combining a surface board layer (1), a core board layer (2), a bottom board layer (3) and a reinforcing layer (4), wherein the surface board layer (1) is a poplar veneer; the core board layer (2) is a poplar laminated veneer lumber; the bottom plate layer (3) is a poplar veneer; the reinforcing layer (4) is made of unidirectional carbon fiber cloth, wherein the core plate layer (2) is made by pressing a plurality of layers of fast-growing poplar veneers into a laminated veneer lumber along the grain assembly, sawing and vertically splicing; epoxy resin adhesives are applied among the surface plate layer (1), the core plate layer (2), the bottom plate layer (3) and the reinforcing layer (4), and the carbon fiber reinforced poplar composite plate is formed by sequentially assembling and cold-pressing.
1. The surface plate layer (1) is a poplar veneer with the thickness of 2.0-4.0 mm, is low in price and has price advantage in actual production.
2. The core board layer (2) is a poplar laminated veneer lumber with the thickness of 10.0-25.0 mm, a plurality of layers of fast-growing poplar veneers are pressed into a batten along grain assembly, and the batten is sliced into a vertically arranged laminated veneer lumber with the width of 10.0-25.0 mm, so that the overall dimensional stability of the board is improved.
3. The bottom plate layer (3) is a poplar veneer with the thickness of 0.5-2.5 mm.
4. The reinforcing layer (4) is made of unidirectional carbon fiber cloth with the thickness of 0.1-0.2 mm, and the mechanical strength of the plate is improved.
The utility model has the beneficial effects that: reasonable structure and good dimensional stability, and can be used as a large-size plate, is not easy to deform and has long service life. The single-sided composite carbon fiber cloth improves the defect of low strength of fast-growing poplar, reduces the using amount of bottom-layer poplar, has a poplar veneer on the surface, is easier to carry out secondary veneering processing, has the functions of water resistance and termite resistance, uses the fast-growing poplar with low price as a raw material, has price advantage and raw material advantage in actual production, and can be used as furniture and a carriage bottom plate.
Description of the drawings:
fig. 1 is a schematic structural view of the present invention.
The specific implementation mode is as follows:
example (b): the carbon fiber reinforced poplar composite board has a finished product thickness of 24.1mm, is formed by combining four layers of structures, and sequentially comprises a surface board layer (1), a core board layer (2), a bottom board layer (3) and a reinforcing layer (4) from top to bottom.
Step 1) core layer (2): the poplar laminated veneer lumber with the thickness of 20.0mm is adopted, rotary-cut poplar veneers with the thickness of 2.0mm are used, urea-formaldehyde resin adhesive is coated, hot-pressed into the poplar laminated veneer lumber, and the poplar laminated veneer lumber is sawed into veneer laminated strips with the width of 20.0mm to be vertically arranged;
step 2) surface sheet layer (1): adopting a poplar veneer with the thickness of 3.0 mm;
step 3) floor layer (3): adopting a poplar veneer with the thickness of 1.0 mm;
step 4) enhancement layer (4): adopting unidirectional carbon fiber cloth with the thickness of 0.1 mm;
step 5), coating epoxy resin adhesives on the surfaces of the surface plate layer (1), the core plate layer (2), the bottom plate layer (3) and the reinforcing layer (4), assembling in sequence, and then cold-pressing to obtain the carbon fiber reinforced poplar composite board;
the embodiments of the present invention have been described in detail, but the embodiments are merely examples, and the present invention is not limited to the embodiments described above. Any equivalent modifications or alterations to this practice will occur to those skilled in the art and are intended to be within the scope of this invention.
