The technical issues of thermal is complicated, volume is big, heating is slow, poor safety performance.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme that：
A kind of composite material heating plate, including multiple heating plate units, each heating plate cell edges are fixedly installed company
Fitting, adjacent heating plate unit are combined into heating plate by connector cooperation；
Each heating plate unit includes core material and is covered in the heating surface layer of core material upper surface or/and lower surface；It is described to add
Hot-face layer includes carbon fibre heating plate, and carbon fiber heating on piece is fixedly installed at least two conductiving metal strips as electricity-linkingup point,
The upper and lower surface recombination of carbon fibre heating plate is stained with non-woven fabrics, and the outer surface of non-woven fabrics is provided with thermoplastic composite layer；Institute
It states core materials lateral surface and is provided at least one temperature sensor, contact and the heating face layer contacts of temperature sensor.
Carbon fibre heating plate is made of carbon fiber, organic fiber and graphite packing, organic fiber as heating plate inside
Skeleton among carbon fiber is scattered in skeleton so that conductive unit is unordered, constitutes current path.After powering on, in external micro-current
Under the action of, carbon crystal molecule does unordered Brownian movement, between molecule irregular movement generate friction, convert electrical energy into heat
Energy.Heat is transmitted to heated object nonmetallic composite cover in such a way that thermal convection current, heat radiation or heat are transmitted, while compound
There is the heat insulation core material of intralamellar part certain heat insulation effect, thermoplastic composite layer to have certain mechanical strength so that compound
Plate has multifunctionality.
Temperature sensor, which is arranged, can accurately measure the temperature of heating surface layer, convenient for accurately controlling.
The problem of non-woven fabrics, thermoplastic composite layer are nonmetallic materials, and there is no electric leakages, security performance
It is good.
Plate unit, modularized production, and easy to disassemble, repair are heated by setting, it is at low cost.
It is further improved, the carbon fibre heating plate is using organic fiber as skeleton, by carbon fiber and electrically conductive graphite filler

Bright movement, between molecule irregular movement generate friction, convert electrical energy into thermal energy.
It is further improved, the thickness of the heating surface layer is 0.6mm -3mm, and thickness is thin, small, takes up space small, together
When heat transfer it is fast.
It is further improved, the heating surface layer further includes being arranged in the overlay film of thermoplastic composite layer outer surface or multiple
Conjunction face layer.Overlay film or composite cover, including metal and non-metal surfaces layer are set according to actual demand, plays anti-corrosion, improve intensity
The effects that.
It is further improved, the core material is cystosepiment, foaming cellular core plate or normal cellular core plate.Convenient material drawing, cost
It is low, it is light-weight, and heat insulation effect is good.
It is further improved, the side of the core material opens up fluted, and depth of groove is 5mm -10mm, and temperature sensor is set
It sets in a groove.Prevent temperature sensor exposed outside, influence measurement accuracy, at the same protect temperature sensor avoid and other
Object collides and damages.
It is further improved, direct current or alternating current may be used to composite material heater plate；Be applicable in voltage be 7V~
220V；Maximum heating temperature is 120 DEG C；Maximum heating rate is 11~13 DEG C/min；Average heating rate be 3~4 DEG C/
min.Pressure-resistant range is wide, highly practical, and quick heating is efficient.
A kind of production method of composite material heating plate, includes the following steps：
1), using machine fiber as skeleton, the fillers such as carbon fiber and electrically conductive graphite is mixed and are evenly distributed with into skeleton, are pressed into
Carbon fibre heating plate is made in type；
2) two copper bars, are arranged in parallel as electricity-linkingup point, copper bar and carbon fiber heating in one side surface of carbon fibre heating plate
Piece passes to carbon fibre heating plate by PU glue stickings, by electric energy by copper bar；
3) the upper and lower surface of carbon fibre heating plate, protection copper bar and good bonding circle of offer, are arrived by non-woven fabric compounded；Nothing
Woven fabric is that the thermoplastic resins such as felt and PP are combined, and the PP resins in non-woven fabrics can melt under the high temperature conditions, with carbon fiber
Dimension heating plate directly merges molding, does not need adhesive, composite instant.By one layer of the coating that PU glue is very thin at the copper bar back side, face
When connect with carbon fibre heating plate, by by it is non-woven fabric compounded reach to carbon fibre heating plate copper bar is further fixed, it is thin
Thin PU glue coats have no effect on the electric conductivity between copper bar and carbon fibre heating plate.
4), thermoplastic composite is overlayed on to the upper and lower surface of step 3) institute forming face layer, carry out compression molding, molding
Temperature is 200~240 DEG C, and heating time is 2~5min, and heating finishes, and during cooling, mold continues to keep closing
State 1min~3min；
5), by numerical control CNC according to design requirement in one side surface milling groove of core material, depth of groove is in 5mm~10mm
Between, multiple temperature sensors are provided in groove；
6), heating surface layer is laid on to the upper surface or/and lower surface of core material by design size, by heat it is compound or
