Benefits of technology

[0007]One particular aspect of the present invention is to provide a process of producing a composite sheet and the structure of the same, the strength of the composite sheet not only can satisfy the industry safety regulation, but also the weight of the composite sheet can be reduced compare to traditional composite sheet, and the cost of producing the composite sheet of the present invention can be effective reduced.
[0010]This invention has several advantages: by carefully choosing the composite materials used to produce the surface layers, and coupled with the present invention, thereby reducing the quantity requirement for the more expensive metal on the surface layers and the core layer of the composite sheet, and due to the bonding method of the present invention the strength of the composite sheet will still satisfy industry safety regulation and the cost of producing the composite sheet can be effectively reduced. The weight of the composite sheet can be light (due to the fact that the more expensive metals are generally heavier), so that it is very convenient for fabricator and installer to assemble many of the composite sheets with each other.

Problems solved by technology

Because quantities of easily accessible natural resources (specifically metals) on Earth are decreasing, the cost of the composite sheet made of exotic metals will be more and more expensive.
However, if we simply decrease the quantities of the more expensive metals for the metallic surface layers 2a and attempt to reduce the cost of the composite sheet in this simple fashion, the strength of the composite sheet would suffer and may not be enough to reach industry safety regulations.

first embodiment

[0033]As shown in FIG. 2 and FIG. 3. a process for producing a composite sheet is presented, and the process comprises the steps of:

[0034](a) provide a plurality of metallic sheets 1 (top, middle, and bottom metallic sheets 1), wherein the metallic sheets 1 are coiled around a coiling roller group 21, and the metallic sheet 1 are made of aluminum, copper, steel, zinc, or titanium.

[0035](b) Uncoil the metallic sheets 1 coiled around the coiling roller group 21 (uncoiling can be done by motor (not shown) or any other power generating equipment, which is beyond the scope of the present invention), then as the metallic sheets are uncoiling, the top and bottom metallic sheets 1 are passed through a stretching roller group 22, and the stretching roller group 22 extends, stretches, and flattens the top and bottom metallic sheets 1.

[0036](c) the middle metallic sheets 1 have top and bottom surfaces (here on now referred as contact surfaces) respectively, place a plurality of adhesive on the...

second embodiment

[0038]As shown in FIG. 4 and FIG. 5, represent the present invention. Similar to FIGS. 2 and 3, except that a plurality of adhesives are coated on the contact surfaces of the middle metallic sheets 1 by two adhesive applying units 25 (only 1 shown) with different vertical positions, and the adhesives are bonding layers of the composite sheet 3.

[0039]The kinds of the adhesives used are not restricted, as long as the adhesives can bond the metallic sheets 1 with one another securely. The temperature of the set of heating rollers 23 depends on the adhesive applying units 25, and only needs to be high enough for proper adhesive bonding.

third embodiment

[0040]FIG. 6 is a process for producing the composite sheet of the present invention. The bonding layers are formed by the set of heating rollers 23. The radius of each third forming roller 243 is longer than the radius of each second forming roller 242, and the radius of each second forming roller 242 is longer than each radius of the first forming roller 241. The metallic sheets 1 are pressed by the first forming rollers 241, the second forming rollers 242, and the third forming rollers 243 in sequence to contact with the bonding layers respectively, and the metallic sheets 1 bond with each other via the bonding layers.

Abstract

A process of producing composite sheet is presented, and the process comprises the steps of: (a) providing a plurality of metallic sheets; (b) bonding the metallic sheets with one another; and(c) finishing the bonded composite sheet that has a plurality of metallic layers.In comparison to conventional single type / solid piece of building material, the present invention results in a dramatic cost reduction in various building industry. With the up-to-date technology, the strength of metallic composite sheet remains within structural grade parameter and meets related specifications. Manufacturers are benefited from the cheaper metallic sheet in the composition while enjoying the same quality look of the outer layer. Furthermore, a structure of the composite sheet is also presented in the present invention.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a kind of composite sheet that can be used as building and industrial material. In particular, it relates to a process of producing composite sheet and a structure of the same.[0003]2. Description of the Related Art[0004]Please refer to FIG. 1, representing a typical structure plan of traditional composite sheet, wherein the traditional composite sheet represents one kind of exterior cladding material in the building industry. The process of producing a traditional composite sheet comprises the steps of (a) putting some plastic materials into an extruder which extrudes and heats the plastic materials (i.e. resin) until the plastic materials are melted; (b) the melted plastic materials are transported to a mold to become a flat core layer 1a of the composite sheet; (c) provide two metallic surfaces layers 2a to bond with the core layer 1a. [0005]As shown in FIG. 1, the structure of a trad...
