Activity #1: Materials Selection Dashboard of a family car; glass fibre is the best material which can be used on familycar dashboard. The material is able to absorb any impact and thus fit for the dashboard. For instance, during crash incidents, the dashboard should not harm the car occupants andthus the glass fibre will be fit (In Zou 2013). In addition, the glass fibre has low reaction time to electric and heat. This ensures that the dashboard does not become too hot from heat from engine. Rivets used in the fuselage of a 747-800; carbon composite material is a key material which can be used for the rivets in fuselage (Messler 2011). The material has high strength and therefore able to offer stability for the rivets. This material ensures that the rivets cannot e broken easily and thus offer stability in holding different parts. In addition,this material can hold different stresses which may be directed to them by the fuselage. The material is able to resist the bending stresses and therefore ensure that the fuselage is intact. Pressure vessel which can contain caustic at a high temperature; Nickel alloy is the best material which can be used at such high temperatures. The high strength of the alloy ensures that they can withstand the heat and pressure in the vessel. The material can also with stand different acidity and alkalinity factors. In addition, the material is corrosive resistance. This ensures that the pressurised stored material is safe. A fuel tank for a car that uses hydrogen liquid as fuel; polyethylene composite material is best for the fuel tank, which has hydrogen liquid. This material is inert and able to ensure that the hydrogen liquid is safely stored (Wypych 2013). The material has high structural strength to withstand the escaping characteristic of the hydrogen liquid. In addition, in order to reduce the weight of the car, lighter materials are required. Polyethylene is lighter than steel which has been used to make the fuel tanks.
A tool used to press gears- aluminium alloy material. This material has high strength which helps to reduce wear and tear on the gears. The tensile strength of the aluminium alloy if high and this ensures that the pressing tool is strong to withstand high forces and cannot be broken easily (International Symposium on FRP Reinforcement for Concrete Structures, & Tan 2003). Addition, the aluminium alloys have low electric conductivity and this will ensure that electric shock will not be experienced during gear pressing. Activity #2 Research Activity Maraging steels Maraging steel is simply steel or iron alloys that have high strength and toughness and have not lost their malleability (Brookes 2016). Nevertheless, these materials are unable to hold good cutting edge. In addition, the steel in this section are in a special class of low carbon ultra high strength and they do not obtain their strength from carbon but the precipitates of inter metallic compounds. The main alloying element composes of 15 to 25 percentage weight of Nickel. In addition, the materials also have secondary alloying materialswhich may include titanium, molybdenum or cobalt (Li et al 2016). These secondary materials are responsible for producing the intermetallic properties which enhance the strength. Figure 1: Maraging steel in Golf stick
