    The Aerospace Industry

    • 1289 Words
    • 6 Pages

    1.1 Overview of aerospace industry Globally, 3.57 billion passengers travelled on aeroplanes during 2015 and the demand for air travel is predicted to keep rising.1 As the frequency of air travel is increasing, it places a pressure on the aerospace industry to improve material performance and the efficiency of their transportation.2 Classically aircraft were constructed from metallic materials such as aluminium and titanium. Therefore, new materials must have specific properties and characteristics that the metallic materials possess, but in addition, present further beneficial properties. Aeronautical materials must possess a high Young’s modulus to prevent shape deformation under stress, high resistance to chemical and thermal degradation, high glass transition temperature (Tg), impact strength, amongst numerous others which are more task specific.3 Advancements in polymer chemistry have resulted in a large number of aircraft moving from metallic materials to composite for their primary structures. The definition of a composite states that it is a new material with superior structural properties, which is formed from two or more materials that differ in physical and mechanical behaviour. The superior structural properties are not present in the individual components from which the composite is constructed.4 High-performance composites used in the primary structures of aircraft are carbon fibre reinforced plastics (CFRP). CFRP’s are mainly used in high-tension loaded…

    clear complexes of helixes or entanglement may indicate the defect of the network and produced the exothermic peak in DSC result. A study on fabrication of nano fiber from alginate (Nie et al. (2008) found that the entanglement may increase the flexibility of chains of alginates. This flexibility may promote the swelling capability of the non-crosslink sample. The AFM analysis measured the average Young’s modulus of 2344.17 MPa for the non-crosslinked film and 2314 MPa for the crosslinked film…

    In the article Superman to the Rescue: Simulating Physical Invulnerability Attenuates Exclusion-Related Interpersonal Biases (Ackerman, Bargh, & Huan, 2013) Julie Huan, Joshua Ackerman, and John Bargh set up a number of studies including a pre-test, study one, study two, and study three to demonstrate the relation between physical invulnerability simulation and positive or negative reactions to being excluded in social situations. They also consider how the reactions of exclusion can change when…

    Tarlock 2007). For nearly a century, clashes between fishers, tribes, environmentalists, and farmers have peaked and ebbed during water shortages and fortuitous wet years. The Euro-American colonial legacy and the settlement and occupation of native territories has resulted in the dispossession of indigenous lands and waters, as well as the strict regulation of indigenous access to waters formerly under their jurisdiction by American government forces (Most 2006). . The Klamath Hydroelectric…

    different elements that are affecting the overall performance and commitment of the Varsity team. The Varsity crew has a large pressure to be the best in the program, because that is what they have been selected for; on the other hand, the Junior Varsity crew has “nothing to lose”. This affects both teams’ motivation, because the J.V team is intrinsically motivated through enjoyment of the sport. However, the Varsity team is extrinsically motivated, because it craves the praise associated with…

    Additionally, Draco demonstrates his cognitive skills, social skills, motor skills, and speaking skills when he played the fishing game with his friend. Playing the fishing game, it requires the cognitive skills which the child need to understand the concept of the game and the social skills which the child needs to take turns. Importantly, the game requires the cognitive skills because “To understand the meaning of each number word, the child must form a mental image of it” (Beaty, 2014, p.…

    Thank you for choosing our school to select three artifacts for a time capsule that will be taken to Mars on the next space mission. Each student has selected their three items, and we are ecstatic! We have each chosen two things that mean a lot to us, and one thing that we think would benefit and/or inform further generations. I can't wait to explain the artifacts I chose and why I'm wanting to put them into the time capsule! One of the first items I would like to put into the time…

    compete for jobs because those coming back from the military might have more experience in a specific field of work. As well for those with degrees in a specific area of expertise. This competition could help create intelligent and hard working people. It would help with employees so they could do their best to be able to keep and get a job. This competition could help motivate the U.S citizens do better in school or to go back to school to get a degree in a better field of work. People would…

    Klamath Basin Case Study

    • 723 Words
    • 3 Pages

    The Klamath River Basin has been fraught environmental resource management issues that have been both highly politicized and publicized in the American West. The problems of water allocation in this region have been the result of conflicting interests between fishermen, tribes, wildlife, and farmers, which rely on scarce water resources for their livelihoods. Doremus and Tarlock(2008) refer to the Klamath Basin as a “problemshed” because its social and ecological problems pervade all of its…
