Composite Materials Report

During World War II, the aircraft manufacturing industry took-off. According to Dr. Bright (1978), “by the year 1944 it was the largest industry in America” (p. 1). It soon declined in the years following due to material flaws, lack in engine performance, and production manufacturing methods.

Through research about composite and bio-composite, there are many advantage and disadvantages in aircraft construction. Definition for composite, a material that are made from two or more constituent materials with significantly different physical or chemical properties when combined, produce a material with characteristic different from the individual components. The individual components remain separate and distinct within the finished structure. In aircraft, the first composite aircraft was in 1916, era of World War 1, when British launched a Bristol Scout from Felixstowe. Between the World War, American experiments with airship composites led to the construction of two aircraft carriers, while the British Short Mayo seaplane composite demonstrated successful transatlantic mail delivery. During the Second World War, some composites saw operational use including the Mistel, the larger unmanned component of a composite aircraft configuration developed in Germany at the end of World War 2. Experiments continued into the jet age, with large aircraft carrying fully capable parasite fighters or reconnaissance drones.

Analysts predict that the Aerospace and Defense industry will experience a number of trends over the next few years. First, the changes in global economy in the Asia/Pacific regions will shift the largest market from North America and Europe to the Asia/Pacific market (Hoover’s, 2018). Second, manufacturers will implement more sustainable and affordable operations. For example, manufactures are researching materials science to develop composites. With composite materials

Fraser Company has been the supplier of metal and plastic fabricated parts for Boeing Aircraft and has recently celebrated its 50th anniversary. In the 1960s, in order

This field of science determines what materials would best suit a work, why, and how. For example, Aluminum is used in airplanes because it is abundant, fairly easy to obtain and very light. It's also strong, resists corrosion and conducts both heat and electricity well. Alloys of aluminum are the primary metals that are used to build airplanes. Aluminum is alloyed with other metals like copper, magnesium and zinc to make it even stronger.

What I am trying to demonstrate in my paper is that airplanes have played such a vital role in our society and culture it has granted us so many of our needs and wants whether it be travelling, eating a certain food, and also one of the major issues is keeping our country safe with warplanes. Why I believe airplanes is such a crucial area to study is because I believe people take for granted everything they have in life. Most of everything they have has been transported by airplanes and is now in the hands of the buyer. it has also allowed family, and friends to see each other faster compared driving, travelling by train, or boat.

On the cost-effective approach, several case studies of WH sites have examined the efficiency of the designation on the socioeconomic impacts. Resulted in discovering a slight effect, which may be described as “Marginal Effects”, besides, argue that significant influences may be comprehended throughout adequate brand awareness parallel with appropriate tourism facilities and amenities managed by cooperative stakeholders (Rebanks, 2009; Hambrey, 2007; PricewaterhouseCoopers LLP, 2007).

Boeing’s newest jet, the 787, is made out of composite plastics and carbon fiber in order to

Abstract: Many people think that going to the outer space is not that complex when talking about the materials of a rocket or space shuttle. Most people believe that metal is all that is needed and that in fact that is all it has. The truth is that it required a lot of research and procedures to come up with the right materials to people to withstand rigorous conditions. In other words, materials had to be engineered to work with extreme heat, cold and pressure changes. Due to some other issues such as collision from debris and unforeseen events the space shuttle had to be cancelled. The risks were too high even with all the engineering of materials.

Aircraft maintenance is very important for aviation industry and Aircraft are required to be maintained after a period of calendar time or flight hours or flight cycles. Aircraft maintenance is the inspection, repair, overhaul, modification of aircraft or aircraft component. Aircraft maintenance generally includes such tasks those tasks required to restore or maintain an aircraft’s systems, components, and structures with Airworthiness Directives or Service Bulletins and this is highly regulated, in order to ensure safe and correct functioning during flight. Aircraft maintenance requirements vary for different size and types of aircraft, experience which most aircraft need various type of preventive maintenance every 25 hours or less of flying time, and minor maintenance at least every 100 hours. Maintenance is influenced by some kind of operation, climatic conditions, storage facilities, age, and construction of the airplane. The profession of Aircraft maintenance requires extreme knowledge and adept expertise in performing the ingrained tasks. The aircraft maintenance engineer who is on duty he has a great responsibility to work professionally to ensure the safety of aircraft, customers and maintain the reputation of the team or company. The aircraft maintenance engineer normally works in an aircraft hangar and line maintenance and The aircraft maintenance engineer will undertake a number of processes including They may specialize by working on particular aeronautical

Introduction: The available life cycle cost (LCC) models and procurement strategies do not take into consideration the varied manufacturing techniques for advanced composite materials. The increased use of advanced composite materials in aerospace

While there are advantages and disadvantages of old and new aircraft, these factors does not wholly depend on the access of an airline. Airlines still rely on its quality service on their customers and truth to be told, the mechanics, built and function of an aircraft is still the starting basis. Several aspects are observed during the process of selection: price/cost, design, structure and

Although aeroplanes go through very stringent checks before flying, more time is needed to check when it is made with the composite material. As composite materials do not break easily, it is hard to differentiate if the interior structure has been damaged at all. Hence, it requires extensive inspection techniques for detection. In contrast, for traditional materials like aluminium, due to its nature, it bends and dents easily. [6] Therefore it is quite easy to find out if there is any structural damage. Based on experience, an aircraft would be grounded for a few days to repair on the composite material while only a few hours would be needed for a traditional metallic part. Moreover, repairs can be much more expensive when a composite surface is damaged. Also, composite repairs are more prone to human error than metal repairs since the quality of composite repair is highly dependent on the process

Since the 1970’s, composite materials have been used in aviation in the form of composite aircraft, and the use of composites has only been expanding. Boeing aircraft from the past, like the 747 circa 1968, were generally made up of only 1% of composite material, whereas relatively newer aircraft, like the 777, which began its service life in 1995, jumped to 11% composites. By 2011, and the introduction of the 787 Dreamliner, the percentage of composites had risen to an astounding 50%...with the fuselage constructed completely of composites, as well as portions of the horizontal stabilizers, vertical stabilizers, and wings. In doing so, it was Boeing’s intention to enhance safety standards while lowering costs in both

The purpose of this study is to explore how some of the different composite materials are produced and how they are used as aircraft parts. The study seeks to answer the research question, why is the use of composite materials so attractive to aircraft designers and are the benefits of using composites worth trying to integrate them into existing aircraft designs? The goal is to analyze the many different uses of composites as aircraft parts and determine whether or not their use is beneficial.
