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 separately characteristic of non-metallic fibers also can correspondingly pass to semi-solid preparation film separately and solidify after finished product.
Various material coefficient of thermal expansion coefficients are inequality, and this has just determined: their random superimposed heating is compound, after the cooling, and vary with temperature in the daily use, and 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 proportion 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 (under-20-50 ℃ of states).
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.

Require: composite board keeps smooth, angularity<3% substantially under-20-50 ℃ normal temperature state.Also promptly require: in the said temperature scope, the thermal coefficient of expansion behind 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,, thereby know the number that to select for use separately again by the thickness of sheet film.Metal decking, A film, B film is superimposed successively.
2), during two different metal deckings, adopt thermal coefficient of expansion to calculate 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<3% substantially under-20-50 ℃ normal temperature state.Also promptly require: in the said temperature scope, the thermal coefficient of expansion behind two kinds of film composite curings can be coordinated with the thermal coefficient of expansion of two metal deckings, guarantees the composite board top and the bottom basically identical that expands with heat and contract with cold.
Step: according to numerical value a, b, c1, c2, Hc1, Hc2, H, determine the numerical relation of Ha, Hb,, know the number that to select for use separately again by the thickness of sheet film.With metal decking 1, A film, B film, metal decking 2 is superimposed successively.
3), during two identical metal deckings, adopt symmetry principle:
Require: with the intermediate layer is benchmark, and the distributing order of two type films can interlock arbitrarily, but will guarantee symmetry up and down, 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 the aforementioned calculation principle to know that the material of following kind, quantity is a kind of proper selection:
