Synopsis
Engineering Materials and Properties provides students with the opportunity to attain a fundamental knowledge of materials used in the different fields of engineering. It will impart cognitive skills to think critically about the materials relevant for industrial and domestic applications. The subject examines the physicochemical properties of materials and how they impact on their design and applications in engineering. The materials studied cover the broad spectrum from hydrocarbons through to metals, lubricants, cements, nanomaterials, polymers and ceramics. The subject adopts a hands-on experimental approach through the use of laboratory practical sessions that enhance the theoretical concepts.
