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…

with a wedge. The one in the lab was an MTS 647 Hydraulic Wedge Grip and an 810 Material Test System. The specimens had strain gages with a Wheatstone bridge to collect data such as time, distance, load, axial strain, and transverse strain in volts which was converted into pounds per force (lbf), pressure (psi), and etc. for data analysis. From the strain gages, evidence can support how and when the specimen material failed under the stress being applied to the specimen. The test would extend…

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…

factors that could drive that price up or down substantially. Here are some of the considerations that influence the cost of a commercial roofing job. Type of Existing Commercial Roof The existing roofing materials will need to be removed before the new roof can be applied. Some roofing materials are more difficult to remove and require additional labor. For example, a built-up roof or modified bitumen roof usually…

which prevents corrosion by blocking oxygen diffusion to enter the passive layer and spreads rust into the internal material. As seen in Figure 1, stainless steel rather than forming a rust layer like other carbon steels, it produces an macroscopically invisible layer in which protects against rusting. [2] Figure 1: Stainless steel compared to other non-rust protection material Given that there…

Silicon carbide has been recognised as an important structural ceramic material because of its unique combination of properties. It is a promising ceramic material that can replace conventional metals and ionic-bonded oxide ceramics such as alumina. Structure of Silicon carbide Silicon carbide is a compound of silicon, a metalloid, and carbon, a nonmetal, and has a giant molecular lattice structure. It has a similar structure with diamond. Each carbon atom is joined tetrahedrally to four…

sectional area of the material. Engineering Strain: Engineering strain is defined as the amount of material that deforms per unit length in a tensile test. Engineering strain is also known as nominal strain. 2) In the figure below, graphically show the toughness of three class materials: Ceramics, Metals, and Polymers (un-reinforced) 3) Where is the elastic recovery in the graph below? 4) What is the relation between the yield strength of a material and…

Ceramics material are compounds between metallic and non-metallic elements where it most frequently oxides, nitrides, and carbides(William D.callister,JR, David G. Rethwisch,2015). This material use for technical applications are commonly based on aluminium oxide. The properties of ceramics which are insulative to the passage of heat and electricity and more resistant to high temperature and harsh environment(William D.callister,JR, David G. Rethwisch,2015). Ceramics in cochlear implants use for…

Corrosion Cracking Stress Corrosion Cracking (SCC) is the growth of cracks with a under the combined effects of a static stress and a specific chemical environment. All SCC failures involve a macroscopic brittle performance, and the ductility of the material is reduced. It is universally acknowledged that there is no single mechanism for stress corrosion cracking (Ford, 1984). Stress corrosion spectrum (Parkins, 1972) demonstrates the significant alloy-environment the mechanism…

contributing factors, they’re not the primary reason why these sheets are so luxurious. Egyptian cotton and bamboo sheets are luxurious because they only use the highest quality materials. In fact, Egyptian cotton is the highest grade of cotton. Bamboo, on the other hand, is one of the highest quality fabric materials in general. However, if you’re looking for the best of the best, premium bamboo sheets only use the highest grade of bamboo. Subsequently, Egyptian cotton and bamboo sheets are…
