Introduction of carbon fiber plates
Carbon fiber board is also known as carbon fiber laminate, at least by two layers of carbon fiber prepreg layered, and then after the curing effect of resin glue to form the whole, the fiber laying direction can be the same can also be the same, Qingxi carbon fiber board, different laying way to get the performance of carbon fiber board is also different. Carbon fiber plate pavement can be divided into two ways, one-way pavement and multi-way pavement, one-way pavement is a one-way carbon fiber plate, is a one-way non-woven carbon fiber prepreg along the same direction of the pavement, applicable to the force direction of a single - the structural components. The multi-directional laminate is the multi-directional laminate, which is the woven carbon fiber prepreg in different directions. On the pavement, the common pavement angle are 0 °, 90 °, 45 °, Shijie carbon fiber plate, according to the performance requirements of the plate, the use of different angles of the pavement, which is also an important factor that carbon fiber materials are different from metal materials, generally selected a metal material, its strength is given, while carbon fiber can be through a reasonable design, as far as possible to take advantage of.
Advantages of carbon fiber plates
Paste carbon fiber reinforcement and adhesive steel reinforcement form and reinforcement mechanism is relatively similar, the next to introduce you to the advantages of carbon fiber plate unique.
1.the advantages of reinforcement method
If the design value of carbon fiber plate tensile strength is approximated as 2000MPa, steel (Q235) tensile strength design value is approximated as 200MPa, then 0.1mm thick carbon fiber plate can be equivalent to 1mm thick steel plate. Almost no increase in the cross-section of the member, carbon fiber light, thin, do not need large construction machinery, transportation, storage, construction is simple, the same amount of work, paste carbon fiber construction period is about 40% of the sticky steel. Compared with steel, carbon fiber is an inert material, not rusting, not easy to be corroded by harmful media, good durability in harsh environments.
2.Material advantage
Carbon fiber also has flexibility, can wrap the complex shape of the components, not very smooth structure of the building's steel surface basic effective paste rate can also reach 100%, paste steel plate is very difficult to achieve 100% effective paste surface, the corresponding acceptance criteria is only to reach 70%.
Carbon fiber plate has its own advantages compared with steel plate, and carbon fiber cloth also has its own advantages compared with carbon fiber cloth, here is a look at what are the advantages compared with carbon fiber cloth.
1.paste carbon plate quality better control
Carbon plate is the original carbon fiber filament through the use of resin infiltration hardened to form carbon fiber plate, the material itself is hard, in the smear glue when the glue layer control, paste the pressure control, paste the effect will not be a problem. In contrast, a series of common problems such as edge warping and bulging will occur in the process of carbon fiber cloth pasting. And carbon cloth paste compared to carbon plate paste substrate requirements to be higher.
2.Good strength utilization
We mentioned above that the design value of tensile strength of carbon cloth in important members is 1600MPa, and the tensile strength of carbon board in important members is 1150MPa, while the ultimate tensile strength of carbon fiber cloth and carbon board are 3400MPa and 2400MPa respectively, and according to the above data, we can calculate their strength utilization rate respectively:
Strength utilization rate of carbon cloth:1600/3400=47.1%
Carbon plate strength utilization rate: 1150/2400=47.9%
It can be seen that the strength utilization rate of carbon board compared with that of carbon cloth does not fall behind.
3.Carbon fiber board has good force effect
After the calculation results of the previous test, the carbon board with the same width and 1.2mm thickness is more than 5 times of the tension that a 300g carbon cloth can bear.
Applications of carbon fiber plates
In recent years, some medium and high-end medical device manufacturers have used carbon fiber composite materials, a high-tech material, to upgrade their products. The specific applications of carbon fiber composite materials in the field of medical devices such as carbon fiber bed plate, breast stent, head rest, DR flat detector, etc. This light weight and strong material not only has the characteristics of fatigue resistance and small coefficient of thermal expansion, but also its excellent performance in X-ray transmission rate, which is especially suitable for radioactive medical devices. According to the relevant experiments, 1mm thick carbon fiber composite plate, its X-ray transmission rate is 96%, scattering and absorption consumption is 4%, the total loss is less than 1/5 of aluminum, so it can be seen that carbon fiber composite material is the ideal material for making radiological medical devices.
