CFRP
GRP
aluminium composite board
concrete
tungsten carbide
reinforced concrete
fibre cement
engineered wood
what is CFRP made of
carbon fibres mixed with polyester resin
CFRP properties include
lightweight
corrosion resistant
hard
tough
good compressive strength
low thermal expansion
CFRP uses
bicycle frames,
tennis racquets
fishing rods
racing car bodies
helmets
what is GRP made of
glass fibres mixed with polyester resin
GRP properties
lightweight
corrosion resistant
hard
tough
good compressive strength
low thermal expansion
GRP uses
pond liners
sports car bodies and parts
kayak shells
boat hulls
what is tungsten carbide made of
ceramic tungsten and cobalt metal
Tungsten carbide properties
hard
tough
resistant to high temperatures
corrosion resistant
tungsten carbide uses
cutting tools eg,
drill bits
kitchen knives
router bits
what is aluminium composite board made of
aluminium and polyethelyne
aluminium composite board properties
lightweight
rigid
tough
malleable
good thermal/sound insulation
good vibration damping
aluminium composite board uses
soundproofing in cars, buildings and boats
signage
what is concrete made of
cement powder, sand, aggregate particles mixed with water
concrete properties
high compression strength
low tensile strength
few surface defects
easy to mould
concrete uses
pathways
beams
blocks
driveways
what us reinforced concrete made of
cement, sand, aggregate particles with low carbon steel rods and water
reinforced concrete properties
good compression strength
good tensile strength
few surface defects
fire resistant
reinforced concrete uses
buildings
bridge spans
grid floors
retaining walls
what is fibre cement made of
cement, sand, aggregate particles, polymer or steel fibres with water
fibre cement properties
lighter than reinforced concrete
hard
tough
good at low temperatures
fibre cement uses
suspended floors
complex geometric shapes
pathways
engineered wood is made of
timber laminates and MF adhesive
