Materials for Design
Format: PDF / Kindle (mobi) / ePub
Over the last 10 years there has been a huge growth in the area of materials and design, but most books on the subject deal with advanced, semi-formed materials (that is, materials sold as sheet, rod, tube, etc.). This new book provides much-needed information on the raw materials, and the 'low-down' on what these materials can be used for.
The information provided in the book allows professional designers and students from a range of disciplines – but focusing on product design – to understand in simple, exciting, thought-provoking, visual terms different qualities and features of materials. The subject is presented from the perspective of design, and relevant case studies are used to inspire designers into new ways of thinking about materials. As well as standard and widely available materials, the book also contains emerging materials such as smart materials and self-healing plastics, offering a comprehensive guide to material selection for designers.
conditions. Production As every child who has ever played with balsa wood will know, it is very soft and can be cut with basic crafts tools. Its open structure also means that it absorbs stains very well, but it does soak up a lot of the stain. Typical applications Apart from model aircraft, it is also used for speed boats, heat, sound and vibration insulation, buoyancy in lifebelts and water sports equipment, theatre props, surfboards, and even as the skeleton for planes in World War II. +
clarity and to some degree scratch resistance. Although anybody who has ever put one of these glasses in a dishwasher will tell you that it won’t take long for the haziness of a well-used glass to appear. One of the advantages of PC is that it is easily blended with other plastics, such as ABS or PET, to enhance the toughness of these additional materials. Increasingly, PC has become associated with BPA, a synthetic oestrogen and potential hormone disruptor, which is used as an ingredient to

Cost �1.28 ($2) per kg. Sustainability issues Producing aluminium is very energy intensive to process and as a result is extensively recycled due to the low energy needed to recycle it in comparison to
is also recovered as a by-product of copper and tungsten mining. Cost �57-76 ($90-120) per kg. Sustainability issues Estimates by the US Geological Survey in 2012 put known reserves of molybdenum at around 20 million tonnes. They also reported that ‘molybdenum in the form of molybdenum metal or superalloys is recovered, but the amount is small. Although molybdenum is not recovered from scrap steel, recycling of steel alloys is significant, and some molybdenum content is re-utilized. The
