Charge level layer, is arranged with the reinforcement of multiple material identical with metal structure frame in parallel along its thickness direction inside metal structure frame,
Metal structure frame is internal fills core, and core is foam.
The above multiple reinforcement can be to be evenly spaced distribution, it is also possible to is uneven distribution, mainly sees sheet material
The distribution of stress point.
Preferably, the material of described metal structure frame is rustless steel.
Preferably, in enhanced type composite material plate construction of the present invention, core is hard polyurethane foams, composite wood charge level
Layer can be alkali-free glass fibre composite, it is also possible to for additive fire-retardant unsaturated paraprex composite.
Because unsaturated polyester resin (UP) is that dihydroxylic alcohols forms with unsaturated dibasic acid at high temperature polycondensation, its main chain contains
There is polymerizable double bond, with all kinds of vinyl monomer copolymerization under initiator effect, obtain the thermoset plastic of three-dimensional-structure.But this
Class plastics are inflammable, and therefore the present invention uses and unsaturated polyester resin adds the interpolation formed after the appropriate right agent of resistance processes
Type flame-retarded unsaturated polyester resin.
Invention additionally discloses the manufacture method of a kind of structure enhanced type composite material sheet material, comprise the following steps:
Step one, makes metal structure frame, and sheet metal encloses formation rectangular structure, and thick along cuboid in inside
Degree direction arranges the reinforcement of multiple same metal material；
Step 2, arranges core inside metal structure frame, core is hard polyurethane foams；
Step 3, metal structure frame appearance cladding at least one of which composite faces, composite faces is alkali-free glass
Fiber or additive fire-retardant unsaturated paraprex composite；
Step 4, is filled with core, outside is coated with the metal structure frame of composite faces and is positioned over compound by inside
On the self-heating platform of sheet metal forming, utilize this self-heating platform that metal structure frame is heated stage by stage, pressurizeed, make metal tie
The internal core of structure frame foams and fills whole internal cavities；
Step 5, material sheet material to be composite takes out after fully solidifying.
Further, in described step 4, point gradient carries out heating pressurization, is first heated to 80-120 degree Celsius, is forced into
50-80MPa, keeps 2-5min；Then proceed to be heated to 180-220 degree Celsius, be forced into 100-150MPa, keep 2-5min.
Carry out an embodiment of heating pressurization as in the above step 4 point of gradient, be first heated to 80 degrees Celsius,
It is forced into 80MPa, keeps 5min；Then proceed to be heated to 180 degrees Celsius, be forced into 150MPa, keep 5min.
Another embodiment of heating pressurization is carried out, point ladder in described step 4 as in the above step 4 point of gradient
Degree carries out heating pressurization, is first heated to 120 degrees Celsius, is forced into 50MPa, keeps 2min；Then proceed to be heated to 220 Celsius
Degree, is forced into 100MPa, keeps 2min.
As in figure 2 it is shown, invention additionally discloses a kind of self-heating platform for composite board molding, including:
The support means 1 of cuboid frame structure, is arranged in support means 1 the safety glass template 2 being rectangle, if
Being placed in support means 1 the heat radiation lamp installation pedestal 3 being positioned at below safety glass template 2, heat radiation lamp is installed and is set on pedestal 3
Being equipped with multiple heat radiation lamp 41, multiple heat radiation lamps 41 all electrically connect between attemperating unit 42, and attemperating unit 42 is with power supply even
Connect；
The surrounding of support means 1 cuboid framework and installing between pedestal 3 and safety glass template 2 at heat radiation lamp
Enclose and be provided with four pieces of thermal-insulating type transparent plexiglass plates；
The top being arranged in support means 1, being positioned at safety glass template 2 is covered with the plexiglass tent of insulation transparent type
5, it is connected for detachable between plexiglass tent 5 with safety glass template 2, and junction is that movable sealing connects；Organic glass
Glass cover 5 is outside equipped with Air pressurizer, limit heating edge pressurization in composite board forming process.
Preferably, heat radiation lamp is installed pedestal 3 and is parallel to safety glass template 2 and is arranged in support means 1.
Because heat radiation lamp is arranged in nonocclusive space, the heat that heat radiation lamp produces easily scatters and disappears, in order to reduce heat
