  1. Other Materials Edexcel – Product Design: Graphics

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

  3. 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

  4. Composites • Carbon fibre • Glass reinforced plastics (GRP) • Medium density fibreboard (MDF)

  5. 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

  6. Modern materials and products • Liquid crystal displays (LCDs) • Phosphorescent pigments • Electroluminescent (E.L.) lighting

  7. 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

  8. Smart Materials • Thermochromic liquid crystals/film • Smart ink • Radio frequency identification (RFID)

  9. Task • Work on your own or in pairs: • Put down the heading you are given • Write a brief description for each material • Find images of example products • Advantages and disadvantages of each material • Composites • Modern materials and products • Smart Materials
