There are various materials which can be used on aircrafts. Composite and alloy materials are the primary component used due to the ability to combine certain materials with different strengths together to create a composite or alloy. These have ultimate properties that are needed to create an aircraft to be used safely in application. Composites are used due to the extreme high strength to weight ratio, although using large amounts of metals can be strong, unlike composites this would be too heavy. Composites essentially are designed to create a lighter aircraft, which over a long period of time, would be more cost effective for company running the plane, due to fuel savings. Materials used in aircrafts, range from metal alloys such as Aluminium-lithium alloys and many more different aluminium alloys, for instance; 2024, 2090, each having desirable properties causing it to be used in industry. To Composites which can range from carbon composites to graphite, aramid, fibre glass. These can also be used together to create graphite-aramid, graphite-aramid-fibreglass, graphite-fibre gl...
Most components of bikes are either made out of steel or aluminium. Aluminium is commonly being used to replace components of steel bicycles as it is much lighter and retains nearly as much strength. Aluminium is more corrosive resistant and has a more aesthetically pleasing surface finish compared to steel. This is extremely important to bicycle design as a product that corrodes less and is lighter appeals to cyclists.
C Series - Design and manufacture of the advanced composite wings for the CS100 and CS300 commercial aircraft.
When the war ended, the military’s demand for airplanes ceased. Even civilian planes met limited demand. Boeing Airplane Co. was competing with war-surplus airplanes. In order to survive, the company began building furniture and sea sleds. Although Boeing received limit...
The future of the aerospace industry will involve gradual changes in the near term, with the prospect of more radical shifts in the decades t...
Composite materials have become extremely useful and since been adapted for aviation. They have been in development ever since the use of aluminum in the early 1920’s. Composites are components that are mixtures of two or more inorganic or organic compounds. One material acts as a matrix, which is the compound that keeps everything together, while the other material provides a reinforcement, in the form of fibers embedded in the matrix.
(1) Plastic (2) Metals (3) Other natural materials such as stone, chalk, Shell, leather, cocoanut, wood etc.
Boeing 787 used two types of interchangeable engines that made 787 a flexible asset that can be moved from one Boeing aircraft to other. This was an attractive offer for both financiers and leasing companies. They were light in weight, less costly and saved fuel as they were made form composite materials. Some attracting features were included such as wider seats, wider aisles, large lavatories, spacious luggage bins, large window for a beautiful view, sky simulated ceiling, noise-reducing chevrons on its engine nacelles and quick and smooth takeoff and landings. They also used non corroding composite to avoid frequent aircraft
Aviation industry deals with more than thousands of people and also spending millions of funds in order to meet the requirements, satisfy the necessities of people and to produce state-of-the-art aircraft. With its objective it is significant to consider the hazards involved and bring out an output with the least extent and under control risks to prevent any loss in terms of life and even profit.
Denture teeth can be made of acrylic poly(methyl methacrylate) (PMMA) or composite resins. PMMA is a polymer - a material made the from joining of methyl methacrylate monomers. Properties of PMMA include resistance to abrasion, chemical stability and a high boiling point. (Jun Shen et al. 2011). However, weak flexure and impact strength of PMMA are of concern as they account for denture failure. (Bolayir G, Boztug A and Soygun K. 2013). Composite denture teeth are made of a three distinct phases - filler, matrix and coupling agents. Out of the types of composite teeth available, nano-filled composite teeth are preferred. Composite teeth have a PMMA coating around the tooth and a high content of filler particles. This gives them strength, higher resistance to forces than acrylic teeth and provides compete polymerization due to the PMMA coating. (Anusavice, K. J., Phillips, R. W., Shen, C., & Rawls, H. R, 2012). If the interface between the PMMA denture base and PMMA or composite teeth was weak, the denture will not be able to sustain occlusal forces, making the base-teeth interface, an entity of significance.
With the intention to avoid these negative impacts and because passengers are now more demanding in terms of safety, manufacturers along with their engineers have perfected those machines by working out state-of-art practices for building up new airplane, during maintenance routines and by focusing on the materials to use for each component of the plane that shows a high level of performance while under stress and reducing so components structural failure.
Since the Wright Flyer first took off from Kitty Hawk, North Carolina, in 1903, aircraft designers have been searching for ever better materials to build aircraft with. Over the years, we have seen construction materials progress from simple wood frames covered with fabric to advanced structures built entirely out of metal. As aircraft designs became more advanced, the need arose for materials which offered both higher strength and lighter weight. Since the beginning of World War II, aircraft construction consisted mainly of structures built from aluminum. Beginning in the 1960’s, NASA and the United States military began experimenting with the use of composite materials in aircraft. This revolutionary material seemed to be the answer the aviation world was looking for. It promised both gains in strength and weight reduction. However, with more and more composites being added to aircraft over the years, problems arose which ultimately may negate the overall benefits of the composites.
The future of passenger aircraft and their manufactures has an amazing outlook. Every year the brightest minds in aviation compile the greatest technological advances towards creating the safest and most economical aircraft on the planet. No detail is over looked, and the bottom dollar is the all controlling factor. From private aircraft to public aircraft, space exploration and beyond, the future is bright for the passenger aircraft market, and everyone who purchases air travel should be excited to see how industry unfolds.
Metals possess many unique fundamental properties that make them an ideal material for use in a diverse range of applications. Many common place things know today are made from metals; bridges, utensils, vehicles of all modes of transport, contain some form of metal or metallic compound. Properties such as high tensile strength, high fracture toughness, malleability and availability are just some of the many advantages associated with metals. Metals, accompanied by their many compounds and alloys, similar properties, high and low corrosion levels, and affects, whether negative or positive, are a grand force to be reckoned with.
Yet before any factory starts to create aluminum castings, the conceptualized product should be examined. Will it meet the standard standards identified by the aluminum industry? Will it be generated using available technology? What tools and machines are necessary to result in the conceptualized product?
Carbon-fiber-reinforced-polymer (CFRP) is a composite polymer made up of carbon fibers and a binding polymer. The binding polymer can be a thermoset resin or thermoplastic polymer(s). Examples of thermoplastic polymers that can bind with carbon fiber to make CFRP are polyester, nylon, or vinyl ester. A thermoset resin that can combine with the carbon fiber to make CFRP is epoxy. The combination of the carbon fibers and a thermoset resin or thermoplastic polymer producing CFRP results in a light weight fiber-reinforced plastic that is tremendously strong. Depending on the binding polymer, CFPRs have a wide range of applications and are used when a light weight material with high rigidity and strength are required.
