Coursework 1- Carbon Fibre composites compared to traditional metallic properties Introduction Carbon fibre is a material made up of thin strips of crystalline filaments of carbon woven together to create a cloth or combined with a resin or ceramics to strengthen the material. Carbon fibre is now overtaking traditional metals in where it is being used and the reasons why will be discussed further on in the report (Happian-Smith 2001: 1). Carbon fibre composites have become the leading material…

Carbon fibers are exceptionally stronger than carbon bulk material. These fibers have very small diameters, typically ranging from 4 to 10 micrometers, which in turn yield a relatively small fiber surface area. Flaws such as dislocations, cracks, and impurities, are virtually inexistent in a specimen of such size, and so the structure is virtually defect free. Because the fibers are kept separated from one another by the matrix, they do not make contact, and crack propagation from fiber to fiber…

A final study that was explored focused on the importance of finite element analysis for analyzing the effects of composite patching on CCT. According to [S3], FE analysis is helpful because it leads to a direct computation of both the SIF and stress-distribution field. This study used 2024-T3 aluminum with a glass and epoxy composite patch. Cyclic stress was applied to patched and unpatched aluminum specimens, and the Mindlin FE Approach was used to analyze the resulting data. Results showed…

North American deserts. The plant has flat fleshy pads, which are modified stems and look like large leaves. Its leaves are small wart-like projections that appear on the stem. The fruits and pads of this plant are rich in slowly absorbed soluble fibers, which help in regulating blood sugar levels (Davidson, 1999). Comfy Beverage Company intends to venture into the business of processing and selling prickly pear juice and prickly pear marmalade. This research paper is a marketing plan that…

that parallel fiber-to-Purkinje cell synapses were strengthened during learning; in contrast, Albus postulated that the parallel fiber-to-Purkinje cell synapses would weaken (he also thought they could strengthen and that the parallel fiber-to-stellate cell synapses were also modifiable.) Albus defended his synaptic weakening argument by pointing out that the parallel fibers should be trained to emulate the post-complex spike pause and not the excitatory phase of the climbing fiber-induced…

Numerous studies have been done on the causes and effects of Ulcerative Colitis in the body that ultimately begin and progress through the large intestine. These studies have led to information that allows physicians to help their patients control the symptoms of this disease and enable them to lead a normal life. However, through the research that has been done no significant information has led to the cure of this disease or what truly causes it in the first place. The cause for this disease…

2.1 Nanocomposite and nanofiller Composite is the combination of two or more different materials that are mixed together in order to bring out the best properties of both material. A nanocomposite is the composite which exhibit at least one dimension of the nanoparticle size material [17]. The nanoparticle size is mainly used as the disperse particle system to enhance or improve the properties of the composite material such as strength, conductivity and wear resistance. The main reason for…

Introduction: Selecting a pair of hunting boots is totally on the hunter and his needs. For serious hunters, who climb deep mountains, spend hours in the jungle and travel to colder regions in search of animals, choosing the right hunting boot is always essential. You will not only need the best quality hunting boot, but you will also need a pair of comfortable and lightweight boots too. Unlike any other shoe or boot you choose for yourself, these boots should be wisely selected. If you have…

A ray of light travels in a straight line. This is true until it passes from one medium (eg. air) into another medium (eg. glass) of a different optical density. When this happens, the ray of light changes speed causing it to bend either towards or away from the normal which is an imaginary line at 90 to the interface between two mediums. This is called refraction. How much it bends depends on the refractive indices of the two mediums which is a ratio of the speed of light in one medium…

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…
