Abstract
The utility model belongs to the automobile technology field and provides a large-scale carbon fiber composite covering member. The covering member comprises a main portion and a fixed connection portion which are formed to be an integral body. Both the main portion and the fixed connection portion are made from carbon fiber composites which include thermoset resin layers, carbon fiber layers and a glass fiber layer, wherein each thermoset resin layer contains, by mass, 45% to 70% resin. The advantages are that the large-scale automobile covering member has a series of excellent properties such as high specific strength, high specific modulus, high temperature tolerance, corrosion resistance, fatigue resistance, creep resistance, conductivity, heat transfer and low thermal expansion coefficient, can serve as a structural material to bear loads, also can serve as a function material to achieve effects, enables the weight of an automobile to be reduced, keeps the crashproof performance, and is convenient for production and low in comprehensive cost.
Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of carbon fiber composite material large-scale covering.
Background technology
Along with developing rapidly of automotive technology, automobile adopts new material and new process more and more, makes people become possibility to car light, low cost, intellectuality, high economy and the requirement of reliability.Although New-energy electric vehicle has zero-emission, the advantages such as energy structure optimizing and driver behavior are convenient, but the new-energy automobile of present stage (referring to pure electric automobile) ubiquity complete vehicle quality is larger, once charging, it is short to hold continual mileage, the larger defect of kilometer unit power consumption, its industrialization and market-oriented process have seriously been restricted, therefore automotive light weight technology becomes and reduces the actual of new-energy automobile cost, an approach more easily, and adopt composite material manufacture automobile body covering piece and other associated components, be to make automotive light weight technology, one of actv. approach of energy-saving and emission-reduction, especially in country, advocate energetically energy-saving and emission-reduction, walk under the Policy Background of intensive and technology innovation type road for development, develop civilian lightweight composite material and not only there is good economic benefit, have more strong social benefit and significance of times, simultaneously, lightweight composite technology also can be for China at other energy, resource, environment, manufacture, the active demand of the pillar industries in national economy such as traffic to high performance structures material, due to existing automobile body part, as bonnet, body rear wall adopts metal foil preparation more, this material not only density is large, also larger to people's injury while crashing.
Summary of the invention
Technical problem to be solved in the utility model is the present situation for prior art, and provides a kind of quality light, and intensity is large, the carbon fiber composite material large-scale covering reducing production costs.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of carbon fiber composite material large-scale covering, comprise main part and be fixedly connected with portion, described main part forms a whole with the portion of being fixedly connected with, it is characterized in that, described main part and be fixedly connected with and all there is carbon fiber composite material in portion and make, described carbon fiber composite material comprises thermoset resin layer, carbon fiber layer and glass layer, and described thermoset resin layer is for containing mass ratio 45-70% resin.
In above-mentioned a kind of carbon fiber composite material large-scale covering, described carbon fiber composite material comprises four layers of thermoset resin layer, layer of glass layer and two-layer carbon fiber layer, and its distributing order is from top to bottom thermoset resin layer, carbon fiber layer, thermoset resin layer, glass layer, thermoset resin layer, carbon fiber layer, thermoset resin layer.
Compared with prior art, the utility model has the advantage of that automobile large-scale covering has a series of excellent properties such as high specific strength, high ratio modulus, high temperature resistant, withstanding corrosion, endurance, creep resistant, conduction, heat transfer and thermal expansion coefficient be little, they both can be used as structural materials bearing load, can be used as again functional material plays a role, when alleviating body quality, also can keep crashworthiness, and be convenient to produce, integrated cost is low, with loss of weight 50% under the rigidity such as steel construction piece and same strength; Modulus >65GPa; Intensity >500MPa.
Accompanying drawing explanation
Fig. 1 is the integral structure schematic diagram of this carbon fiber composite material large-scale covering;
Fig. 2 is the inner structure schematic diagram of carbon fiber composite material.
The specific embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
In figure, main part 1; Be fixedly connected with portion 2; Thermoset resin layer 3; Carbon fiber layer 4; Glass layer 5.
As depicted in figs. 1 and 2, this carbon fiber composite material large-scale covering, comprise main part 1 and be fixedly connected with portion 2, main part 1 be fixedly connected with portion 2 and form a whole, main part 1 and be fixedly connected with and all there is carbon fiber composite material in portion 2 and make, the innovation of the utility model maximum is that the carbon fiber composite material of using in Aviation Industry is applied on the large-scale covering of automobile, like this in proof strength, integral body has reduced weight, carbon fiber composite material comprises thermoset resin layer 3, carbon fiber layer 4 and glass layer 5, thermoset resin layer 3 is for containing mass ratio 45-70% resin, so not only alleviated weight, strengthened intensity simultaneously, here thermoset resin layer 3 is machine polymeric silicon MQ resin, improve like this interface adhesion and the shock resistance of composite material.
Carbon fiber composite material described here comprises four layers of thermoset resin layer 3, layer of glass layer 5 and two-layer carbon fiber layer 4, its distributing order is from top to bottom thermoset resin layer 3, carbon fiber layer 4, thermoset resin layer 3, glass layer 5, thermoset resin layer 3, carbon fiber layer 4, thermoset resin layer 3, the utility model adopts comparatively advanced quick liquid moulding manufacturing technology to develop large area composite material large-scale covering, in addition adopt raw MAT'L relatively cheap or relatively integrated (quantity is integrated and function is integrated) to reach the object that reduces the cost of raw material, adopt low-cost resin system, in carbon fibre fabric, adopt large-tow carbon fiber, the low-cost carbon fiber composite structure part of developing with the rigidity such as steel construction piece and same strength under loss of weight 60%, Combination property remains unchanged, break through traditional fabric ply sequence, preparation becomes rigidity fibers preform, set up curing deformation anisotropic thermal viscoelastic model, solving product size stability and precision controls.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from the defined scope of spirit of the present utility model.
