Description
Technical field
The invention belongs to automobile using lightweighting materials technical field.
Background technology
Carbon fiber is high intensity, the new fiber materials of high modulus fibre of a kind of phosphorus content more than 95%, and it is claimed
For " king of new material ".Carbon fiber " soft outside but hard inside ", carbon fiber density less than steel 1/4, intensity be 5-7 times of steel, there is fibre
Tie up two big characteristic of soft machinability and strong stretching resistance.Carbon fiber has many premium properties, the axial strength and mould of carbon fiber
Amount is high, and higher than performance, fatigue durability is good, and X-ray transparent is good, and no creep, density is low, superhigh temperature resistant under non-oxidizing atmosphere, heat
The coefficient of expansion is small and has anisotropy, and simultaneously corrosion resistance is protruded insoluble and in-expandable in organic solvent, bronsted lowry acids and bases bronsted lowry, and good conduction is led
Hot and electromagnetic wave shielding etc..
Carbon fibre composite has high intensity, high rigidity, high-fracture toughness, corrosion-resistant, high resistant compared with other materials
Buddhist nun, product excellent in mechanical performance, it is safe, designability is strong and parts are integrated the features such as, have been widely used automobile
In industry, automobile service life, fuel efficiency and traffic safety and riding comfort is greatly improved, has been acknowledged as auto industry field most
Preferable lightweighting materials, its a variety of processing and forming technology are also widely used.
The application of domestic carbon fiber is mainly in aerospace field, sports equipment field and industrial circle.Wherein, move
Equipment accounts for the overwhelming majority, although and civil aviation, the vehicles, new energy equipment, engineering construction etc. application
Start to start to walk, but application level is relatively low.
The moulding process of carbon fibre composite mainly has at present:Hand pasting forming, injection molding, BMC shaping,
Sheet molding compound shaping, laminated into type, resin transfer molding, Wrapping formed, injection moulding and pultrusion etc..Early stage car
With the production of part using hand paste technique and sprayup process, but hand paste and spray technology (die sinking molding) seriously pollute ring
Border, labor intensity is big, and the quality of product is difficult to control, mainly for the production of the part of simple shape in auto parts, it is difficult to full
The requirement of the sufficient production of auto industry metaplasia and environmental protection.Injection molding is that carbon fiber is molded with thermoplastic resin direct injection.It is suitable
For manufacturing complex contour, accurate size or product with metal insert.And pultrusion is thermoplastic resin and carbon fiber
In an extruder by heating pressurizing melting after, uniformly extruded by screw rod turn, cooling and shaping.RTM (resin transfer moulding)
The general principle of shaping is to be laid on fibre reinforced materials in the die cavity of closing in advance, locking die, with pressure by resin glue
Liquid injects die cavity, is impregnated with reinforcing material solidify afterwards, then stripping forming.RTM moulding process is mainly characterized in that closed mould operations, nothing
Pollution, briquetting pressure is low, reinforcing material can be laid by design requirement, product two sides is bright and clean and complex-shaped large-scale system can be made
Product etc..The technical research time is short, and suitable for product renewing, technological equipment investment is few, suitable for small lot, the automobile knot of multi items
Component, such as engine water tank, heat shield, hood.Sheet molding compound (abbreviation SMC) is by unsaturated polyester resin, low
A kind of prepreg of dry plate shape of the compositions such as shrink additives, filler, curing agent, thickener, releasing agent and reinforcing fiber, it has
Have that superior electric property and decay resistance, shrinkage factor are low, intensity is high, convenient formation, light and engineering design are easily flexible
The features such as, it is particularly suitable for industrialization large-scale production.Its mechanical performance can compare favourably with part metals material, thus extensively should
For in the industries such as haulage vehicle, building, electronic/electrical gas.But its cost is higher.As domestic SMC (slice plastic) is raw
Produce the continuous improvement of manufacturing technology, compression molding technology, the raising of the reduction, government of die cost to requirements such as working environments,
Originally many products for the technique such as pasting, spray by hand and being molded, hardening time length, low production efficiency, labour greatly, to environment
There is pollution, start progressively to use SMC die press technology for forming.Domestic SMC is widely used to electrical equipment industry, as switch board housing,
Arc quenching plate, every backplate etc.；For automobile, tractor driving chamber enclosure, railway carriage window frame, seat are prayed；Facility for building, such as bathe
Basin, purification tank etc..
At present, Lamborghini releases SUV vehicles, and chopped carbon fiber and resin premixed is put into steel by its duplex forging
Mould, then heating pressurization, after three minutes, you can complete, more original preimpregnation of whole process-cycle 12 hours and RTM techniques 3
Hour greatly shortens, and greatly reduces production cost.Therefore, either industry, product and market, or enterprise is in itself, it is all right
This kind of technology has strong demand, not only needs more advanced inexpensive carbon fiber technology of preparing, it is also necessary to which more advanced carbon is fine
Tie up composite material preparation process.
