Composite Material Technology
Composite material technologies enable the fabrication in designing lightweight, structurally strong, and assemblies for a range of applications. The technology prepares scholars to work in various fields of specialization, among them automotive industries, marine industries, aerospace industries, marine industries, bridge and building industries, textile industries, aerospace industries, and assembling industries. Students who successfully complete this program, the composite material technologies, are eligible to entry-level employment in positions of composite technicians. They are capable of fabricating a number of composite shapes, and familiarizing with the terminologies of the field.
The study of composite material technologies nurtures specialists who have unique competence in various aspects of composite manufacturing as well as design technologies. The study of composite material technologies enable production of automotive spare parts, which are fire retardant, protected from the Ultraviolet rays, and with same coefficient of thermal expansion as steel. (Mujta.&Sapuan, 2010).
Applications of composite materials technology in automobile industries
Composite materials technology enables the automobile industries to come up with lighter vehicles. It involves the use of materials that are relatively lighter, compared to those used in the past. The technology enables the replacement of heavier materials such as steel with lighter, yet reliable ones. For instance, it has facilitated the replacement of steel-made bodies of vehicles with stronger plastics, which are reliable, lighter, and convenient. The technology has also enabledmanufacturing of economical vehicles. The materials used for manufacturing modern vehicles are mostly plastics, which are far much cheaper and easily accessible compared to steel. Moreover, it follows automatically that the lighter the locomotive the machine, the lower the amount of fuel required. Furthermore, most engines of the modern automobiles are efficient, and faster. This reduces the risk of often breakdowns, and saves more time due to high speed with which they move.(Miravete, 1993).
The cost of laying up complex shapes with composite materials, especially plastics, is lower compared to that of stamping metals, such as steel. Additionally, their assembling is less hectic because they are less bulky, and the distortion of unrequired shapes is easier and faster. This fact makes the technology more efficient and faster for the manufacturers.Some of the typical application of composite materials technology on automobiles include; the interior fittings of vehicles, such as sidewalls, seats, interior bulkheads. They are also used on cabs on trains, which uses the application of complex aerodynamic profile.
Many governments and environmental conservation organizations across the world continuously demand for tighter restrictions on the emissions of vehicles. The environment is vital for the existence of all living organisms including humans. Hence must be handled with cautiousness. However, many automobiles emits harmful gases that results from incomplete combustion of fuel, which comes about due to inefficiency in their engines. Because of that, the composite material technology has come up with highly technical engine formations that ensure complete combustion of the fuel. It has enabled the invention of equipment, which neutralizes the incompletely burnt fuel before they are released into the environment. This has facilitated the manufacturing of ecofriendly automobiles through less emission into the atmosphere.
Fiber reinforced composites materials are popular in high performance products such as aerospace, which need to be lightweight, yet has the strength to accommodate harsh loading conditions. The composite material technology has led to the invention of such aerospace component as tails, fuselage, wings, and propellers, which are lighter in weight but stronger enough to perform their roles in the planes. The carbon composite is as well, a relevant material in the modern launch vehicles, and heat shields, which enables the re-entry phase of spacecraft. They are used to make yokes of aircrafts, solar panel substrates, and antennae reflectors.
Other applications of composite material technology within the automobile industry include the reduction of noise, improved styles of vehicles, and general part performance of the locomotive machines. Modern automobiles are made up of technical engines, which are free from extreme friction, and have a noise regulator. This help to reduce the amount of noise produced by the machines during movement. The technology has equally led to the development of highly stylish automobile machines that are more comfortable, faster, and beautiful. These machines are more attractive by sight, and efficient in service delivery. Moreover, the technology has led to the invention of more complex parts of the machines, such as the gearboxes, and engines that are less vulnerable to breakdowns.(Mukhopadhyay, 2005).
knowledge for global, regional, national and industry issues with situations related to materials
The collection of raw materials for variuos industries across the world, especially the automobile industries, is reliant to varius nations. Major manufacturers of automobiles, such as Toyota, Mitsubishi, Bavarian Motor Works (BMW), among others do import the raw materials from other countries. Such materials include the metal works for building of body works, E-glass for windscreens, and polymer plastics.
Various countries across the world have different materials, such as steel, which are necessary in the manufacture of automobiles. Because of that, the producers of these materials work in collaboration with these industries, automobile, to ensure a constant supply of raw material. Availability of inadequate supply of raw materials leads to a lower production of the products, which subsequently leads to imbalance in the markets. If the demand of automobile products is greater than the supply, results to increased pressure on the manufacturing companies. This consequently leads to increase in the prices of these products in the markets.
Therefore, various regions across the world must work with one another to ensure adequate supply of raw materials required through imports and exports.
knowledge for global, regional, national and industry issues with situations related to welding and fabrication
Welding and fabrication is pivotal in the automobile industries. The assembly of various parts of automobiles is subject to welding. The metals, plastics, and glasses must be cut, and then crafted into specific shapes that are required by the manufacturers. These activities are fully reliant to the availability of power, which is vital for welding.
Many fabrication shops across the globe have specialty processes that they develop based on the needs of their customers. These fabrications are important in the manufacturing of stylish automobiles that are demanded by the ever-changing markets. Metal fabrication is a process involving the construction of machines and structures from raw materials, and the manufacture of automobiles is exception.
Metal fabrication in the automobile industry includes the designing of auto bodies. Welding argon makes the frame and suspension-system components. Helium welds the stainless steel. This is because it provides better appearance, well speed and penetration required in the assembly process of automobile machines.
Several fabrications in the automobile industry are distributed to the global markets. They sell their products in diverse places of the world. This helps in the expansion of market in different parts of the world.
In conclusion, composite material technology has contributed majorly in the growth of automobile industries. It has led to production of reliable vehicles that are efficient, and economical. The cost of production in the manufacturing companies has been cut due to the use of cheaper, but effective materials. It has as well led to the manufacture of lighter automobile machines, which translates to the level of speed they are capable of moving. The lighter the machine, the faster it moves. The technology has developed lightweight parts to improve gas mileage, hence mitigating the impact of damaging emissions to the environment. These emissions contribute to the depletion of the ozone layer. Thus, the control of these harmful emissions has led to the manufacturing of ecofriendly machines.
In addition, it is quite evident that the success of any automobile industry is reliant to global, regional, and national collaboration. The supply of raw materials to the manufacturing companies is achieved by collective efforts from different parts of the globe. Nations must cooperate with each other through the import and export of various products of production in these industries. They must be willing to work together in order to control the imbalances that may arise in the global markets as a result of inequity between the supply and demands of the products in the markets.
