Abstract
The invention discloses a kind of automobile sheet material 3D printing technique, it is combined using the carbon fiber hand pasting forming method in the layering fusion sediment method (FDM methods) and carbon fiber technique in 3D printing, realizes that the technique includes：Three-dimensional CAD digital-to-analogue is created first with computer CAD software, then carries out with 3D printer fusion sediment superposition, the honeycomb sandwich of automobile board is printed in sandblasting post processing with 3D printer；Then use the carbon fiber manual pasting forming process in carbon fiber technology：In automobile board surface brush epoxy resin, gummy solidification is treated, the dry cloth of carbon fiber is layered on automobile board surface, then post processing is carried out to smooth with sand paper water mill after cured with polishing machine and can be obtained by finished product.
Description
Technical field
The present invention relates to 3D printing field, more particularly to a kind of automobile sheet material.
Background technology
With the development of auto industry, quality requirements more and more higher of the people to automobile.In order to adapt to development and the consumer demand in epoch, car manufactures all over the world are also innovated constantly, not only improve effect and quality of auto parts and components, and various improvement are also carried out to some frocks and production line for producing auto parts and components, to improve production efficiency and reduce cost-effective.Current automotive body structure part and half hitch component or metallic article, for the realization of automotive light weight technology, developed country replaces metal body structural member and half hitch component using new carbon fibre material in the world, to reach automobile lightweight.
Carbon fiber（CF）As reinforcing material of new generation, with good mechanical property, high temperature resistant, fine corrosion resistance, organic solvent-resistant, acid, alkalescence are good.In actual applications, carbon fiber is commonly used as reinforcing fiber, and carbon fibre reinforced composite has high intensity, high rigidity and light-weighted characteristic, widely used.The weight of vehicle body can be greatly reduced in application of the RTM carbon fiber component products on body of a motor car, significant to improving fuel efficiency and reduction motor vehicle exhaust emission.In recent years, with the fast development of global economy, people are more prone to the pursuit to high-end product.
Present automobile carbon fiber auto parts and components manufacture is also rested in traditional RTM techniques manufacture, because tradition RTM automation technolo degree is relatively low, molding cycle is longer, and the cost of carbon fibre composite is higher, than general material molding time it is long, and productivity also by industrialized production rate is low and the compacting of cost of labor and cause limits throughput.
The content of the invention
It is an object of the invention to provide a kind of 3D printing of automobile sheet material.It is combined using 3D printing technique and carbon fiber technology, it is set to possess preferable mechanical property while mitigating auto parts and components weight, solve traditional RTM automation technolos degree relatively low, molding cycle is longer, and the cost of carbon fibre composite is higher, than general material molding time it is long, and productivity also by industrialized production rate is low and the compacting of cost of labor and the problem of cause limits throughput.
In order to realize the purpose of foregoing invention, the present invention provides following technical scheme：
（1）Automobile sheet material 3D printing technique, realize that the technique is combined comprising 3D printing technique and carbon fiber technology, the honeycomb sandwich of automobile board can be gone out with high performance resin material printing speed with 3D printing technique, carbon fibre material is then attached to the outside for going out automobile board with 3D printing technique printing speed with carbon fiber technology by resin gel；
（2）Described automobile sheet material sandwich design is alveolate texture；
（3）Described 3D printing technique is fusion sediment method (FDM methods)；Described carbon fiber technology is carbon fiber hand pasting forming technology；Described 3D printing technique and carbon fiber technology can be combined according to actual production technology using different methods to be used.
The advantage of the invention is that：
（1）Automobile sheet material sandwich is designed as alveolate texture, while mitigating auto parts and components weight it is possessed preferable shock resistance；
（2）Automobile sheet material is combined using 3D printing technique and carbon fiber technology, can effectively improve industrialized production rate.
Embodiment
Set forth in the present invention is a kind of automobile sheet material 3D printing technique, is further illustrated below by way of specific embodiment, but the present invention is not limited only to following examples.
Embodiment one
(1) three-dimensional CAD digital-to-analogue is created first with computer CAD software, then fusion sediment superposition is carried out with 3D printer, print the honeycomb sandwich of automobile board；
(2) first 3D printing product surface is polished with sand paper, is polishing to no impression state, then cleaned out foreign matter and dust of 3D printing product surface etc. with high pressure air rifle and rag；
(3) carbon fiber is combined on 3D printing product with epoxy resin, after resin solidification, sand paper water mill resin surface is polished smooth；
(4) by the product polished file sharpened edge, then with polishing fluid and pneumatic polisher polishing product surface, finished product is obtained.
Present invention employs above-mentioned technological process, the automobile sheet material of production using it is cheap can jointing material and carbon fibre composite combination, the high cost of carbon fibre composite is broken, and had both had the not defeated hardness in steel, the intensity, toughness and impact resistance of product are substantially increased again.
Claims (5)
