What Are The Major Applications of Carbon Fiber Sheets?

Carbon is perhaps the most abundantly found elements on this planet. It is present almost everywhere, and with the advancement in the field of science and technology, different types of applications have been figured out. But, when we talk about the applications of carbon, we usually refer to form of carbon fiber. The inception of carbon fiber sheets has proved to be a boon for a wide number of industries, and as more researchers are being carried out, the number of uses is also increasing. Below are some of the prime applications of carbon fiber.

Applications of carbon fiber sheets

  • In the field of aviation, carbon fiber is proving to be an excellent material for the production of aircrafts. Carbon fiber is quite strong in nature, and it is very much light in weight. As a result, the aircrafts made from the sheets of carbon fiber are highly durable and safe as well. Owing to the lightweight nature of carbon fiber, more amount of efficiency is also being added to the airplanes.
  • Likewise, in the production of spacecraft also the use of carbon fiber is showing great results. The spacecraft made from the sheets of carbon fiber is much more efficient and capable as well.
  • In the arena of sports, there are a lot of things that are being made with carbon fiber, such as badminton, tennis racquet, golf stick, and many more. Even running shoes are being made from carbon fiber. This is the reason why carbon fiber manufacturing is increasing at an impressive rate. There is no dearth of suppliers in the online market.
  • Talking about the application of carbon fiber in the medical field, there is a lot that can be mentioned in this regard. Production of artificial limbs has been greatly benefited with the development of carbon fiber. Now the prosthetics are much lighter in weight and they are more durable too.
  • In the automobile industry, vehicles made from carbon fiber are getting more popular, and it is due to the durability that the sheets offer to the vehicles.

All about carbon fibre

You will be amazed to know that carbon fibre is a type of material that is not only super strong but it is also light in weight. Moreover, if you talk about the strength than it is five times as strong as steel and also two times the stiff but then also it weighs less than two third of the steel. The structure of the carbon fibre is like that of the human hair and it is twisted together in the way the yarn is done. The manufacturing procedure of the carbon fibre involves both the combination of mechanical and the chemical process. At first, the material is stressed in the form of a thread and then it is heated at very high temperature but a precaution has to be taken care of during the process that it does not come in contact with the oxygen. The reason behind it is that the fibre does not burn with the proper oxygen supply and thus it goes through a process known as carbonization. Success has not been achieved in producing a high amount of carbon fibre as because it is very much expensive and another reason is that there is lack of skilled labor.

At the time of processing of the entire process, some pieces of carbon fibre breaks and then they get circulated in the air in the form of fine dust particles. The main demerit of these dust particles is that it is health hazards when inhaled. If you talk about the skin problem then let me inform you that the chemical that is used to coat the fibre contains chemicals that may cause irritation to your skin. Therefore it is recommended that people who work in this area should wear a protective mask and also wear protective clothing or you can even use skin cream which will help you to protect from the dust. If you talk about prepreg composites than it is nothing but a common term that is used for the fabrics and it has been pre-impregnated with a resin system.

The carbon fibre sheets are often used in the high-quality cars, boats, planes and especially the formula one race cars. On an addition, it can also be used for the purpose of marine decoration and general entertainment. We all know that most of the automobile is made up of steel and thus if this steel is replaced by the carbon fibre sheets then the weight of the automobile will decrease up to sixty percent. Consequently, the decrease in the weight of the car will also reduce the consumption of the car fuel by thirty percent. The carbon fibre gave lots of advantage to the car manufacturer as now they can manufacture a car with smaller and efficient engine, it will help to reduce weight, increase in the fuel efficiency and at the same time, other different kinds of the engine are also developed.

Use of carbon fiber in the automotive industry

Car makers are always looking for new technology to improve performance and achieve cost-effectiveness. Such technology also helps them increase productivity in order to meet increasing productivity.

Carbon fiber has gained increasing attention over years for many car makers because of its advantages over replacements.

Over the years, carbon fiber composites and carbon fiber panels have been desirable over metal counterparts because they are lightweight. In automotive, this is essential for fuel efficiency. But carbon fiber panels and composites are also desirable in many industries for their strength and weight advantage too, meaning they deliver high strength for low weight.

Steel has dominated the automotive industry for so long and it is possible that high volume carbon fiber manufacturing will replace steel as the material of choice for future cars. Today, autoclave composites continue to be produced in large volumes.

While aerospace has adapted well enough to low production of fiber composites, autoclave composites, and carbon fiber panels, there has to be mass production of these products if they must dominate the automotive industry. Part of the campaign that will help in the mass production of these components is the creating of mixes of carbon fiber and plastics, which has simplified the manufacturing processes. This has helped in the advancement of the industry beyond the most common applications of carbon fiber panels.

Carbon fiber reinforced polymer (CFRP) is the most used type in the high-end automobiles and supercars. It is a carbon fiber bounded by a polymer such as epoxy resin. It delivers a very high strength-to-weight ratio. It also has a low density of 1.6g/cc, making it lighter than steel without compromising on strength.

For fuel efficiency purposes, carbon fiber has helped since a 10% reduction in weight can save up to 6-8% of fuel in automobiles. So carbon fiber is a great focus because of the great focus on fuel efficiency.

It is applied in body construction, making carbon fiber hoods, along with roof panels, rocker panels, and air splitters. Carbon fiber is also a component of wheels and helps achieve faster acceleration and better control.

Storage & Handling of Prepregs

Composite materials are now widely used in various industries because of the advantages they have over ordinary materials. For instance, they can provide desired high strength of material in aerospace, without adding unnecessarily weight in component.

Prepreg composites should be stored in a cool and dry or in a refrigerator. You also need to allow the prepreg to reach room temperature on removing from the refrigerator, in order to prevent condensation. Prepreg composites can stay for up to 12 months when stored at a temperature of – 18 ºC. The matrix determines the tack life at 23 ºC. Storage and handling are two important factors you need to consider when buying autoclave composites and prepreg composites.

However, prepegs have a low risk when being handled due to the below reasons:

1. Both sides are covered by protective coverings and the coverings are not to be removed until assembly lay-up. In addition, the prepeg composites need to be cut into the desired shapes before the coverings are removed, so no handling will be necessary before that.

2. They do not have any loose fibrous dust. They are also splash-free, do not leak or spill. This is in comparison to the wet lay-up methods involved in the manufacture of fiber reinforced composites. In this case of fiber reinforced composites, the dry fiber and liquid resin are used.

3. They are volatile and have a moderate/low tack level at normal room temperature.

Protecting yourself :-

It is important to learn how to handle autoclave composites and prepreg composites, particularly how to protect your hands and body. You should wear gloves and ensure arms are covered to avoid any skin contact with prepegs. Otherwise, touching them repeatedly touch prepreg with unprotected hands might lead to allergic reactions.

There are also fibrous materials that result from machining cured products and you should be careful when dealing with this because inhaling it can be dangerous. You should ensure to install positive dust extraction and collection systems at the cutting zone. You should also prevent dust formation and ignition sources when machining cured products as thus can cause fire. Dust from products that have carbon fiber parts is a good conductor of electricity.

Methods Applied in Carbon Fiber Fabrication

Carbon fiber fabrication is a great method for constructing or making weightsensitive components and products because the material has a very competitive low-weight characteristic. Carbon fiber also adds strength to these components and products like carbon fiber business cards. Carbon fiber fabrication is also employed in production of spas, bathtubs, shower stalls, truck cabs and many other common home and industrial-use products.

Carbon fiber fabrication begins with the selection of the fabrication technique. Selection depends upon part design, speed, cost and end-use or application of the item. Below are some of the methods to consider:

  1. Hand layup is the most basic of all fabrication methods. In this method, layers of dry fabrics or carbon fiber sheets are placed on a tool to make a laminate stack. Then resin is applied on the layers through resin infusion process. The alternative is to lay on the tool, a fabric that has been pre-impregnated with resin.

Wet layup process involves compacting the layers by placing plastic sheet materials on top (called vacuum-bagging) or by hand using rollers.

Curing in this method is achieved in a number of ways. The most basic form of curing involves adding a catalyst or hardener additive into the resin and occurs at room temperature. Debulking not only consolidates the layup but also removes air trapped in the resin matrix that would otherwise create undesirable voids (air pockets) in the laminate that could weaken the composite.

Increasing temperature quickens curing. A vacuum, oven and pressure can be used to add heat during the curing process. A vacuum is initiated before curing using a vacuum bag placed on top of the whole layup and attached to the tool. This method is advantageous as it can remove gases that result when the matrix is undergoing through chemical curing processes, thus consolidating and strengthening the materials further.

Pressure curing in fabrication of carbon fiber manufacturing is done by way of an autoclave. Modern systems use computer methods to monitor and control the temperature, vacuum, pressure and inert atmosphere in the autoclave. The autoclave is very expensive and many who own it cure several parts simultaneously. Heat curing involves raising the temperature for some time then lowering it to room temperature. Other methods include Electron-beam (E-beam) curing.

2. Open molding: This is a low cost method of making fiberglass composite products. The technique is used to manufacture a wide range of components, including large, noncomplex shapes such as spas, bathtubs, shower stalls truck cabs. There are two options in this case, namely, hand layup and sprayup.

In hand layup, workers compact laminates by hand using rollers. It is being replaced by high-speed production methods such as hybrid injection. In the sprayup carbon fiber fabrication technique, the mold is treated with a mold release, and then gel coat is sprayed to the mold and the mold is ready for fabrication to start.

3. Hybrid injection molding or thermomolding: In high volume molding, industries use compression molding, injection molding, and hybrid injection molding or thermomolding. In injection molding process, chopped glass fiber is forced through a heated barrel using a ram or screw-type plunger. This method can produce as many as 2,000 small parts per hour.

Hybrid injection molding or thermomolding involves mixing of plastics and composites processes. An example is the SpriForm. This method of carbon fiber fabrication involves using both compression and injection molding in a single 90-second fabrication process. It has been used in automotive industry to make a tailored composite seat back that is 40 to 50 percent lighter than its steel version.

Filament winding is also used to make carbon fiber sheets. It uses a long, cylindrical tool called a mandrel suspended in between two end support and used to place place fiber onto the tool in a predetermined manner. Computer-controlled filament-winding processes are available today.

Other highspeed production methods includes tube rolling method used to produce finite-length tubes and rods. Tube rolling involves cutting the material into very fine pieces, laying them on a flat surface, and then rolling a mandrel over the pieces at high pressure and heat.

Pultrusion involves pulling the reinforcing fiber (usually roving, tow or continuous mat) through a heated resin bath and making the specific shape or carbon fiber sheet as needed.

Other methods are centrifugal casting, automated tape laying (ATL) and automated fiber placement (AFP).
