Other Materials
• Composites• Modern materials and products• Smart Materials

Composites
• Carbon fibre– Sports equipment– Excellent strength to weight ratio– Very expensive, only available in black, hard to recycle
• Glass reinforced plastics (GRP)– Vehicle bodies– Excellent strength to weight ratio– Expensive, high quality mould needed
• Medium density fibreboard (MDF)– Flat pack furniture– Consistent in all directions– Heavier, dulls blades quicker

Modern materials and products
• Liquid crystal displays (LCDs)– Digital watches and TV’s– Goes dark when a voltage applied– In TV’s has RGB layers
• Phosphorescent pigments– “Glow in the dark”– Absorb energy from light and stores– Releases slowly at night
• Electroluminescent (E.L.) lighting– Used for LCD backlighting and advertisements– Converts electrical energy into light– Waterproof and highly visible

Smart Materials• Thermochromic liquid crystals/film
– Forehead thermometers– Reacts to temperature
• Piezoelectric crystals– Converts movement into electricity and back– Used in inkjet printers to push out ink
• Smart ink– Also known as electronic ink (or e-ink)– Kindle– Displays only use energy when the display is refreshed
• Radio frequency identification (RFID)– A method of identification– Uses tags to store and track data– Used in libraries, factories etc
