Content Inside: Harmonics Volume 3, Issue 1 September 1999 Harmonics The Engineering Explorations Newsletter What is Materials Engineering? Why do we put hot coffee in ceramic or styrofoam cups instead of metal ones? Why is it more comfortable to wear a fibreglass cast on a broken arm than a plaster cast? Why are pick up trucks made out of aluminum, steel and plastics instead of stone? Why do some artists use oil paints and others acrylics? Well, the easy answer is that some materials are just better suited to one purpose than another. Ceramic and styrofoam insulate our hands from the heat of boiling water better than metal; fibreglass is much lighter than plaster; aluminum, steel and plastics are more versatile and moldable than stone; and, oil paints remain wet and workable longer than acrylics. The material you use for a particular job really depends on what you’re trying to do. Materials engineering is all about knowing what materials to use for a job. It’s also about studying the properties of materials, developing new materials and finding new ways to work with existing materials. Engineers who specialise in materials work in many different fields. Some work in the petrochemical industry because many modern materials, such as synthetic rubbers and plastics, are made from the by-products of petroleum refining. Others work in the automotive and aerospace industries. Engineers in these fields are really interested in harnessing the heat resistant properties of ceramics for use in engines. Still other engineers might study all the materials related to housing - insulation , bricks, wood, cement etc. - or to clothing manufacture. Aboriginal peoples have been materials engineers for generations and generations, using and transforming materials from the natural environment for day-to-day needs. • Animal hides are tanned or otherwise treated then sewn for use as footwear, pouches, clothing and shelter. • Bone, stone, shell, antler and ivory are or have been us ...
