- elimination of timber defects, easy to form parts, good strength/weight ratio, sustainable
- buildings, bridges and other structures
New materials- kevlar- composition, features and application
- fibre, with is often combined with resins
- exceptional toughness and tensile strength combined with light weight
- bulletproof vests, puncture resistant tyres, aircraft construction
New materials- graphene- composition, features and application
- two dimensional form of microscopic carbon particles with a honeycomb like atomic structure
- can be rolled into very thin and hollow tubes, good tensile strength, hardness, heat resistance and electrical conductivity, lack of recyclability
- medical treatment, ‘nanoelectronic’ devices, advanced coatings, battery manufacture
New materials- precious metal clay- composition, features and application
- microscopic particles of metals such as gold and silver bound together in a pliable medium
- easily hand shaped before firing inan oven at 700 degrees
- jewellery, decorative items
New manufacturing methods- electrohydraulic forming- method, advantages, applications
- sheet metal forced against a formed by a shockwave from an electrical spark in a water tank
- uses one side former, fast, greate detail possible, material evenly distributed
- electrical appliance cases, car parts
New manufacturing methods- direct metal laser sintering- method, advantages, applications
- a laser fuse materal particles, layer by layer
- complex, strong and lightweight parts can be made. Undercuts and internal voids possible
- one off prototypes and test parts
New manufacturing methods- fibre injection moulding- method, advantages, applications
- uses pellets of glass or carbon fibre filled polymers such as polyamide
- parts produced are strong, stiff, lightweight and economical to mould. Facilitates sustainability by reusing carbon fibre waste
- lightweight parts for aerospace, automotive, sports/medical equipment
New manufacturing methods- laser beam welding- method, advantages, applications
