The specific embodiment:
We find:
Metal has the phenomenon of expanding with heat and contract with cold, and the thermal coefficient of expansion of metal is lower than general nonmetallic materials.
The fiber of general paper fiber, diablement fort fiber, wood fibre, most of Inorganic Non-metallic Materials has expansion and contraction property; And the fiber of glass/glass fiber, most of chemical fibre, fraction Inorganic Non-metallic Materials has the cold character that rises of pyrocondensation.The different characteristic separately of non-metallic fibers also can correspondingly pass to semi-solid preparation film separately and solidify after finished product.
The thermal coefficient of expansion of various materials is not identical, and this has just determined: their random superimposed heating is compound, cooling after, and vary with temperature in routine use, serious out-of-flatness, warping phenomenon can appear in composite board.
So, through complicated calculation of thermodynamics design as can be known: after adopting suitable superimposed order compound according to rational ratio on the film of the non-metallic fibers of two class opposite nature, its macroscopic property (as thermal coefficient of expansion) can be near sheet metal in certain temperature range (such as under-2-50 ℃ state).
The present invention is exactly in conjunction with above-mentioned principle, solves the difficult problem of the composite board flatness that how to guarantee multiple material.
Concrete calculating principle is as follows:

Require: composite board keeps smooth, angularity substantially under the normal temperature state of-2-50 ℃
Also namely require: in the said temperature scope, the thermal coefficient of expansion after two kinds of film composite curings is near the thermal coefficient of expansion of metal decking.
Step: according to numerical value a, b, c, Hc, H, determine the numerical value of Ha, Hb, then by the thickness of sheet film, thereby know the number that can select separately.Metal decking, A film, B film is superimposed successively.
2), during two different metal deckings, adopt thermal coefficient of expansion calculating principle II:
Suppose: the thermal coefficient of expansion a after the A film solidifies, thickness Ha; Thermal coefficient of expansion b after the B film solidifies, thickness Hb; The thermal coefficient of expansion c1 of metal decking 1, thickness Hc1; The thermal coefficient of expansion c2 of metal decking 2, thickness Hc2; Composite board gross thickness H.
Require: composite board keeps smooth, angularity substantially under the normal temperature state of-20-50 ℃
Also namely require: in the said temperature scope, the thermal coefficient of expansion after two kinds of film composite curings can be coordinated with the thermal coefficient of expansion of two metal deckings, guarantees that composite board top and the bottom expand with heat and contract with cold basically identical.
Step: according to numerical value a, b, c1, c2, Hc1, Hc2, H, determine the numerical relation of Ha, Hb, then by the thickness of sheet film, know the number that to select separately.With metal decking 1, A film, B film, metal decking 2 is superimposed successively.
3), during two identical metal deckings, adopt symmetry principle:
Require: take in the intermediate layer as benchmark, the distributing order of two type films can interlock arbitrarily, but will guarantee that the up and down is symmetrical, because symmetrical structure can guarantee that generally composite board has flatness preferably.
Step: the quantity of A film and B film can be chosen arbitrarily, and symmetrical staggered layer, the metal decking 2 of metal decking 1, A film and B film is superimposed successively;
Adopt above-mentioned calculating principle to know, the material of following kinds, quantity is a kind of proper selection:
