a composite is a mixture of two or more materials join together to create a new enhance material.One material is known as the matrix while the other is reinforcement
Carbon fibre reinforced polymer
CFRP consists of woven carbon fibre strands encased in polymer resin
Carbon fibre strands have a very high tensile strength and the polymer resin is lightweight and rigid .
Used for tennis raquects where strength to weigth ratio is important
Kelvar properties
Kelvar is:
lightweight
extreme durable
high tensile strength to weight ratio
high resistance to heat, corriosion
What can kelvar be used for
it is often used in protective clothing such as police body armour where the fibre is woven in a lattice that provides protection against a knife attack
Glass reinforced plastic
GRP is a composite of glass fibres and polyester resins.
Glass fibres create rigidity and the resin makes GRP tough and lightweight
Difficult to recycle becase the process of combining glass and resin cannot be reversed
