Which of the following composite materials matches this description?
A lightweight, flexible and extremely durable fibre that has excellent resistance to heat and damage from chemicals. It is often used in protective clothing. It is not a composite in its own right, but is often used as the fibre component of other resin based composite materials.
Carbon fibre reinforced polymer
Glass reinforced plastic
Kevlar
Which of the following composite materials matches this description?
A composite of glass fibres and polyester resin. Tough, lightweight and rigid. Common uses include boarts, hockey sticks and car body work.
Carbon fibre reinforced polymer
Glass reinforced plastic
Kevlar
Which of the following composite materials matches this description?
High tensile strength to create high-performance engineering material. Found in the manufacture of racing bikes due to its high strength to weight ratio, along with the ability to produce streamlined shapes.
Carbon fibre reinforced polymer
Glass reinforced plastic
Kevlar
