New Materials Flashcards
Structure and properties of kevlar
woven for strength, interlocked structure. Nylon. high tensile strength, very hardwearing and good tear resistance and cut
Structure and properties of Gore-tex
thin membrane sandwiched between inner and outer material. waterproof and breathable
properties of conductive threads/ fabrics
electrical currents can pass through.
Structure and properties of microencapsulation
process traps liquid or solid substance within fibres of materials eg, scented fabric
Properties of Nomex
fire and heat resistant properties. reduce combustion when exposed to naked flame.
GRP properties
corrosion, chemical resistant, good strength to weight ratio. labour intensive, cheaper than CRP.
boats, kayaks, helmets.
CRP properties
lightweight, high strength to weight ratio, good tensile strength, waterproof and chemical resistant, expensive
sports cars
Properties and use of graphene
highly conductive, flexible, stretchable, strong and light
- medical, electronic, energy industries
Properties and use of metal foams
UV light, high porosity, low thermal conductivity, high compression strengths
- car crumple zone/ bumper
Properties and use of titanium
high strength to weight ratio, hypoallergenic, anti corrosive, easily formed and welded
-jewelry, aircraft
Properties and use of coated metals
chemical and impact resistance, increased abrasion
-Teflon, fabric shears
Properties and use of LCD
thin, compact, crisp sharp image, bright colour, low power consumption
-watches, microwaves, flat screen tv
Properties and use of nanomaterials
carbon nanotubes, fullerenes, quantum dots
-films, electronics
What litmus paper does and examples
Ph levels detected.
Diff colour depending on ph
Eg. Pool water testing or skincare product testing.
What Photochromic pigment does and examples
Change in colour in response to uv light exposure.
Eg. Colour changing sun glasses
