Abstract
The utility model relates to a carbon fiber/aramid fiber composite material for an automobile and an automobile fender covering. The carbon fiber/aramid fiber composite material for the automobile comprises two layers of same or different high-strength fiber cloth, and the two layers of same or different high-strength fiber cloth are fixedly connected through vinylester resin. As the composite material of carbon fiber cloth and/or aramid fiber cloth is adopted, not only does the automobile have an attractive appearance, and the goal of reducing the weight by 30-50 percent can be achieved from the aspect of achieving a weight lightening effect simultaneously, but also the strength cannot be reduced, thereby being more beneficial to energy saving and emission reduction.
Description
Technical field
The utility model relates to a kind of composite material for cars and fender covering, especially a kind of automotive composite material and fender covering that uses carbon fibre and/or aramid fiber.
Background technology
Carbon fiber is a kind of new material of mechanical property excellence, and its proportion is less than 1/4 of steel, carbon fiber resin composite material tensile strength generally all more than 3500Mpa, be steel 7-9 doubly, tensile modulus of elasticity is that 23000-43000Mpa also is higher than steel.Therefore the specific strength of CFRP is that the ratio of intensity and its density of material can reach 2000Mpa/ (g/cm
3) more than, and the specific strength of A3 steel only is 59Mpa/ (g/cm
3) about, its specific modulus is also than steel height.The specific strength of material is higher, then member dead weight is littler, specific modulus is higher, then the rigidity of member is bigger, indicated the broad prospect of application of carbon fiber in this sense in engineering, take a broad view of the excellent properties of multiple emerging composite (as polymer composite, metal-base composites, ceramic matric composite), many people expect, the human epoch that just entering into a composite extensive use on material is used from the iron and steel epoch.
The aramid fiber full name is " PPTA ", English is Aramid Fiber, be a kind of novel high-tech synthetic fibers, have superhigh intensity, high-modulus and high temperature resistant, acid-fast alkali-proof, premium properties such as in light weight, its intensity be steel wire 5-6 doubly, modulus is steel wire or glass fibre 2～3 times, toughness is 2 times of steel wire, and weight only is about 1/5 of steel wire, under the temperature of 560 degree, do not decompose, do not melt.It has good insulation performance and ageing resistace, has very long life cycle.Fanglun l414 has high intensity, greater than 28 gram/dawn, is 5～6 times of high-quality steel, and modulus is steel or glass fibre 2～3 times, and toughness is 2 times of steel, and weight only is 1/5 of steel.(obdurability of Fanglun l414 also makes it cut and process unusual difficult, needs expensive specific purpose tool).The continuous serviceability temperature scope of Fanglun l414 is extremely wide, can normally move for a long time in-196 ℃ to 204 ℃ scopes.Shrinkage factor under 150 ℃ is 0, does not decompose under 560 ℃ high temperature and does not melt, and hear resistance more wins aramid fiber 1313 one raises, and has good insulation performance and corrosion resistance, and life cycle is very long, thereby wins the good reputation of " synthetic steel wire ".
Carbon fiber and aramid fiber all are high strength fibres, can be complementary aspect toughness, and aramid fiber has multiple color coordination carbon fiber to use the aesthetic property that strengthens product simultaneously, and the weakness of aramid fiber is to merge relatively poor with the interface of resin.Carbon fibre/aramid fiber composite material relies on characteristics such as its high strength, lightweight, at automotive field very big application prospect is arranged.But existing at present materials used in auto manufacturing intensity can not play good the cooperation with material weight, can not increase the intensity of material when reducing weight.
The utility model content
The utility model has designed a kind of automobile carbon fibre/aramid fiber composite material and fender covering, the technical problem of its solution is that existing materials used in auto manufacturing intensity can not play good the cooperation with the weight of material, can not increase the intensity of material when reducing weight.
In order to solve the technical problem of above-mentioned existence, the utility model has adopted following scheme:
A kind of automobile comprises two-layer identical or different high strength fibre cloth (3,5) with carbon fibre/aramid fiber composite material, and is fixedly connected by vinyl ester resin (6) between the described two-layer identical or different high strength fibre cloth (3,5).
Further, described two-layer identical or different high strength fibre cloth (3,5) be carbon cloth and or aryl fiber cloth.
A kind of fender covering, described fender covering is made up of two-layer identical or different high strength fibre cloth (3,5), and is fixedly connected by vinyl ester resin (6) between the described two-layer identical or different high strength fibre cloth (3,5).
Further, described two-layer identical or different high strength fibre cloth (3,5) be carbon cloth and or aryl fiber cloth.
This automobile has following beneficial effect with carbon fibre/aramid fiber composite material and fender covering:
(1) the utility model because adopt carbon cloth and or the composite of aryl fiber cloth, not only outward appearance is beautiful, from realize lightweight effect aspect can reach reduce 30%-50% target simultaneously and intensity can not reduce, help energy-saving and emission-reduction.
(2) the utility model because adopt carbon cloth and or the composite of aryl fiber cloth, can satisfy standard and the easy-formation of automobile with material, can effectively control the content of resin and fiber, adopt aramid fiber to reduce cost, reduce the frock expense.
