Abstract
The invention discloses a composite material engine connecting rod. The composite material engine connecting rod comprises, by weight, 40-48% of graphite fibers with carbon content more than 97%, 45-55% of resin, 3.3-3.8% of a curing agent and 1.2-1.8% of rare earth. A manufacturing method of the composite material engine connecting rod comprises the following steps of 1, chopping carbon fibers, stirring the chopped carbon fibers and resin to obtain a uniform mixture and carrying out molding, or chopping carbon fibers and carrying out granulation injection molding on the chopped carbon fibers and resin, 2, putting the molded product into a container and carrying out vacuum-pumping under negative pressure of 5-6kg, 3, pouring the product into a curing agent-containing liquid resin, 4, carrying out pressing under the pressure of 5-6kg for 30min, and 5, carrying out aging and qualitative processing. The composite material engine connecting rod has the characteristics of high temperature resistance, corrosion resistance, light specific gravity, good molding process, less technical processes, environmental friendliness, easily available and cheap materials, industrialization convenience and recyclability and satisfies processing and manufacturing requirements of integral bodies and parts of all motor vehicles.
Description
Technical field
The present invention relates to matrix material Application Areas, particularly relate to a kind of all-composite engine connecting rod.
Background technology
The world is in green energy resource auto age, and automotive light weight technology problem is all put in the first place by various countries automotive engineering technician.Next be durable in use, fuel oil is few, load-carrying is many, traveling is fast, safe and reliable, comfortable.And all seeking the electric power energy automobile of replacing fuel oil; to preserve our planet the common homeland of the mankind; in the world today; a lot of developed country all passes by and experiencings decocting of atmospheric pollution haze misery, and can administer haze process and electromobile truly needs again very long years.Human knowledge is one of source of haze to motor vehicle fuel, want motor vehicle to adopt minimum oil consumption and power consumption, first need automobile self lightweight, each automobile is heavily relieved to 300-350 kilogram weight by 2.8 tons, 1.2 tons are heavily relieved to 130-150 kilogram, or less than 100 kilograms.If continue to use motor vehicle fuel function to need to continue lightweight on the light-weighted basis of car body, engine weight is reduced, need engine body (piston, connecting rod, bent axle, rocking arm), all to alleviate respectively, finally just can reach engine lightweight, oil consumption reduces object.
Existing connection rod of automobile engine many employings metal or alloy material is made, because material is than great, cause the total quality of engine heavier, add the energy consumption of vehicle, and existing other materials cannot meet intensity and the crocking resistance requirement of engine link, how to found a kind of sturdy and durable, intensity is high, high temperature resistant, corrosion resistant new all-composite engine connecting rod, makes automotive light weight technology, the green new energy motor industrialization of final realization, becomes the target that industry is badly in need of improving.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of all-composite engine connecting rod, makes its intensity high, high temperature resistant, corrosion-resistant, light specific gravity, and technique is simple, and material source is easy to get, thus overcomes existing material than great, the deficiency that quality is heavy, energy consumption is high.
For solving the problems of the technologies described above, the invention provides a kind of all-composite engine connecting rod, comprise the graphite fibre that weight ratio is the carbon content more than 97% of 40-48%, weight ratio is the resin of 45-55%, weight ratio is the solidifying agent of 3.3-3.8% and weight ratio is the rare earth of 1.2-1.8%, its manufacture method is: by after short for carbon fiber cutting with resin agitating evenly after moulded section or by after short for carbon fiber cutting and resin granulation injection moulding, then the product after shaping is put in container and vacuumize negative pressure 5-6 kilogram, then the liquid resin containing solidifying agent is injected, be forced into again 5-6 kilogram 30 minutes, finally by aging, qualitative art breading.
Further, the rare earth that described all-composite engine connecting rod comprises graphite fibre that weight ratio is the carbon content more than 97% of 43-45%, weight ratio is the resin of 48-52% and the solidifying agent of 3.3-3.8% and 1.2-1.8%.
After adopting such design, the present invention at least has the following advantages:
Adopt this all-composite engine connecting rod than existing engine link weight saving 80%, and intensity improve twice, through overaging, qualitative Technology process, rub resistance, high temperature resistant, be applicable to regular being in rub compared with the engine link worked in overall situation, long service life, quality is good, there is high strength, high temperature resistant, corrosion-resistant, light specific gravity, moulding process is good, reduce processing sequence, environmental protection, material source is easy to get, inexpensive, facilitate industrialization, the feature such as can be recycled, this engine link adopts aging, the process of subtractive Technology, can not to expand with heat and contract with cold phenomenon because amblent air temperature changes generation, affect engine work and use properties, meet all fuel oils, the application of gas engine.
