Carbon Fiber Composite Essay
Comparison of carbon fiber composite to traditional metallic materials
Metallic materials have homogeneous characteristics. That is they have similar properties at every point. Metallic materials also are same all angles. This is different in regard to carbon fiber. Carbon fibers are neither isotropic nor homogeneous.
Advantages of carbon fiber
Carbon fiber is a strong intensive, thin fiber, made of molecules of pure carbon that are from synthetic fiber. Example of pure carbons is rayon with no oxygen. This fiber is used on strong composite materials in automobiles, architectural structures, aircraft and other areas where light materials have the capacity to withstand high stress are required. Carbon fiber has variety advantages they are include:
Carbons have high strength compared to weight. Strength is energy for each unit at failure, intensity dividing it. This is due to carbon fiber being long flat ribbons. Direction of laying carbon should also be considered. The direction maximizes the strength the carbon, hence they should be aligned to a stress oriented direction. The strength is higher in terms of length but not across.
Carbon products are also rigid, that is the depth at which the materials deflect at stress. When they bend or stretched they are intact they never lose their form. Fatigue resistance of the materials is also super. This is due to the layers, that make them are very stiff unto any pressure that will be exerted to them.
Carbon materials are also fire resistant. Due to manufacturing process and the cursor material, carbon fiber can be processed to soft materials. These materials can be integrated to manufacture firefighting clothes. Carbon fiber is also chemically insensitive or inactive, hence making it usable in fire which has corrosive agents.
Carbon materials are biologically inactive, X-recommendable and non-toxic. Due to this characteristic it makes carbon material so likeable in the medical field. In implantation and repairing of tendons and e-equipment prefer carbon oriented materials. The non-poisonous quality also makes carbon maintenance cost affordable, that is with harmful materials all will have to put place, to ensure they are kept safely.
Carbon fiber also has good tensile energy. This is a capacity at which the material can withhold, when either stretched or pulled with a lot of pressure without contraction. The contraction modality is referred as Necking. Carbon fibers are also non corrosive leading them to resist corrosiveness in highest degree.
Carbon materials are also very light materials. This is the most prominent property in regard to carbon materials. It makes them to be mostly used in the manufacturing of automobile equipments, architectural structures, aircraft and other equipments that may require light materials.
Carbon materials if well fabricated can stay for a long period, even in a worse environment. With its long staying, carbon can be easily formed various structures and products. It also allows transmits radiation, which makes a better imaging component. Thermal expansion is also regulated in a manner that structures are not affected.
Carbon materials are faster in production. They also have high adaptability, in forming of tubes and sheets of different types. These tubes have high quality that can be applied in any environment and departments. Poles manufactured via carbon fiber have low thermal expansion, superior mechanical resistance and low specific weight.
Pre-pregs are well established and bulged fibers and fabrics. They are mostly used in the airplane. They are preferred because they are always in a form of ready to use, this avoids use of additives, hardeners and heat resin. Moved pre-pegs are made from matrix system which comes up via expansive research and development. They require high production rate which have effects on composite materials with respect to their processing characteristics. The high production rates leads to composite materials put in a wrong direction, due to this it makes the carbon material to lose their strength. At the end the weight takes over the strength which end up carbon material ineffective.
High production rate also makes the composite materials to be hardy. Due to this, composite materials are in a position to be broken down to form various structures and shape. Also the production rates results to lose of tensile energy. This makes them not have the capacity to withhold whenever they are subjected to pressure, that is when stretching or pulling them. Hence they are necked easily. Also high production rate leads to remove of resistance to corrosivenesses.
This rates also makes the materials non-biodegradable, the material turn to be dangerous if exposed to the environment. That is like the carbon monoxide gases realized by cars, which is toxic to the environment. It also leads to breaking of a lot of structures of the composite which makes it so weak. In the course of the weakness of the material, they lose the fatigue resistance characteristics, which makes them either dissolve or break easily. Due to weakness also the lifespan of the composite material to decreases.
The rates also provides oxygen, in the presence of oxygen the composite materials are prone to burning. If in any case the composite materials burn, they lose their structure, their design, their shape. Also the burning makes the materials to be chemically sensitive and be heavy. The burning also facilitates lose of rigidness of the materials, hence they doesn’t deflect to stress at all rather than they obey to stress. With above composite materials are not required to pass through high rates of production.
Long processing time needed for carbon materials. To acquire the best needed carbon fiber a number of processes are required. This takes a lot of time making companies to seek for alternative methods in the manufacture. For this reason, aluminum is used; aluminum has a higher production rate. The carbon fiber cannot allow the use of automated method; this brings the opportunity for the use of aluminum.
Carbon materials, lack to realize the material s weight saving potential. Fiber uses excessive material which ought to be saved for other uses.
Aluminum is better suited to higher production volumes. This is because of the availability of alloys; in which it can be used in the manufacture of cars or planes. For instance the Maranello based company, insists that with aluminum it can produce up to 30 cars in a day. Because of production speed procedures in the use of time, the aluminum offers the best alternative. Aluminum is better suited for the higher production of materials, explained by the use of alloys.
The technology used in the making of the materials is not exploitative to the materials potential. This leaves the materials unused which brings about wastage. Composites offer a potential which is not exploitable unless labor intense low rate technologies are used. The fiber is not fully exploited because of high resin content and excess fiber.
Aluminum is not only lighter but also gives a car its polar moment of inertia. This contributes to better handling and the process of heating the aluminum, improves its properties of deformability for crash absorption. Aluminum allows a variety of fastening techniques which would be used as bonding adhesive. It allows welding which causes less heat distortion on the materials, which should be done by hand and the automated process done by the robots. Friction stir welding uses low temperature but also it offers some physical challenge. It is better for simple flat surfaces and shapes. But there is anticipation towards the use of molding rather than welding.
Carbon fiber is expensive this is explained by its numerous processes. For the carbon materials to be of the desired, it must pass through many processes such as autoclave molding. This makes them to be expensive, most of the companies always desire to minimize coasts hence seeking an alternative.
The carbon fiber can only be used to manufacture lower potential quality products, especial those with small size. While aluminum can be used commercially and in larger products such as planes. This is because aluminum is a very light metal. This property reduces dead weight and energy consumption while increasing load capacity. Its application can be adapted to the application of modified alloys.
Aluminum is highly durable, making the end products to have longer life spans last, which is an advantage for the manufacture of quality products.
Aluminum can be recycled without altering its qualities. This makes it desirable since the products made from aluminum have the qualities. Unlike the carbon fiber which does not possess the qualities, it can only form substances which once used they cannot be reused.
Unlike carbon, aluminum is resistant to most atmospheric environments; i.e. does not corrode or rust. This makes it the best material to manufacture the cars. Aluminum, can allow unique architectural and structural sections to be designed and meet the desired needs. The specific performance can be achieved by the reduction of costs and expenses.
Effects of High Production Rate of much standard class of vehicles.
Some of the techniques used to make composite components, its by the use of preleg carbon fiber reinforce. The parts are heated under pressure to produce professional quality parts with a high quality. The effects of their usage are felt over various uses in the manufacture of standard class vehicles.
The vehicles have a lower lifespan; this is one of the effects that give the composite its properties. Cars made out of carbon fiber. The life span of the fiber is not as higher as that of aluminum. The durability of ought to manufacture quality parts.
Vehicles produced by vacuum bagged are considered to be expensive in nature and their production is not desirable. This is explained by the presence of few cars which are formed by the composite. Most of the manufacturers have moved to aluminum which is considered cheap to produce.
The fiber, has the opportunity to be used as the parts of the cars, only when a low production rate is required since most of the people have chosen to use aluminum to manufacture the parts. The affects if the cars made from carbon.
The process of manufacturing has many effects to the environment and the individuals. When carbon is burnt, it produces toxins which are not good for the lungs. The smoke produced, may be hazardous this is because there is no alternative method of production.
The prepreg carbon fiber is easy to handle and can use a method wirh regard to the production, of ten other methods. The fiber required some materials which may be, difficult to analyse the production. Vacuum bagging which may be used for the lamination purposes.
High production rates may result to delays. This is because of the nature the fiber materials which require a complex feature to explain. They also give the opportunity to analyze the processes required giving them an identity. The delays have an impact to the main production result. Hence, the production which requires multiple units, use of robots is ideal.
