fibreglass
GRP-glass reinforced plastic
glass fibres come in a roll/ weave
polyester resin (thermoset) is added in to a mould
used for canoes, motobike etc.
good to strength to weight ratio
range of colours
kevlar
fabric- can be worn
polymer fabric- combined with resin
very strong- x5 stronger than steel - very light
used for body armour
reinforced concrete
mixture of steel bar and concrete
concrete has low tensile strength but steel bar has high
uesed in construction
