The density of carbon fiber enhancement resin base composite material is 1.5-2.0g/ cubic centimetres, and this only has in auto industry often
The 1/4-1/5 of ordinary carbon steel, the aluminium alloy than commonly using is also light by 1/3 or so, but the mechanical performance of carbon fibre composite
Better than metal material, its tensile strength is higher than 3-4 times of steel, and rigidity is higher than 2-3 times of steel.Using carbon fibre material, mitigating
While body quality, it also may be such that power demand is smaller, and then using smaller driving engine and suspension arrangement, it is dynamic by reducing
Can and reduce danger of burst, the iterative result of this spiral will cause body quality further mitigate.Therefore carbon fiber is combined
The light weight effect that material replaces original steelwork is obvious.Energy absorption capability carbon fibre composite in an impact is steel
Thus be accordingly used in body structural components with 4-5 times of aluminium has good crashworthiness.In foreseeable future, carbon fiber material
Material will turn into one of material essential in automobile manufacturing process.
Carbon fibre material be able to can also be broken through by providing distinguished high-tech feeling dazzling sensory effects simultaneously
The limitation of traditional handicraft, realizes unique moulding, therefore carbon fibre composite is also very suitable for being used as vehicle exterior cladding element.
During the present invention is realized, inventor has found that prior art at least has problems with：Carbon fibre material
It is with high costs, more than ten times of common iron are reached, so significantly limit its large-scale application on common volume production automobile.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of weight for solving to mitigate engine compartment cover, and reduction fuel oil disappears
Consumption, reduces the requirement of the discharge of pollutant, while can guarantee that collision safety and the controllable all- composite engine cabin of cost again
Lid.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：A kind of all- composite engine hatchcover,
Have：
Bonnet body, described this volume surrounding of bonnet uses carbon fibre composite, and internal layer uses glass
Fibrous material, internal layer and outer layer connection.
Carbon fibre composite and the glass fiber compound material thickness is 0.5mm.
The glass fiber compound material density is 1.8g/cm3.
It is cementing using polyamine ester adhesive between the internal layer and outer layer.
The outer layer is laminated the structure of layer of glass using one layer of carbon fiber, and two layers of outermost layer is carbon fiber layer, carbon
Fiber laying has eight layers, and glass fibre has seven layers.
Carbon fiber laying fiber angles are respectively 0 °, 90 °, 0 °, 90 °, 0 °, 45 °, -45 °, 0 °.
Carbon fiber laying fiber angles are respectively 0 °, 45 °, 90 °, 45 °, 0 °, -45 °, 90 °, 0 °.
Carbon fibre composite outer layer and glass fiber material internal layer are made using vacuum hot pressing methodology.
A technical scheme in above-mentioned technical proposal has the following advantages that or beneficial effect, using carbon fiber and glass fibers
The advantage of two kinds of unlike material composites can be made full use of by tieing up the mode mixed, while manufacturing cost is greatly lowered again,
So being conducive to large-scale promotion to use.The weight of mitigation engine compartment cover is solved, fuel consumption is reduced, the row of pollutant is reduced
The requirement put, while can guarantee that collision safety again and cost is controllable.
