Composites
Science: KS3, topic 2.1.26
Composites
Composites are made by embedding a material known as the reinforcement (fibres or fragments) into the matrix (material that surrounds the reinforcement, acting as a binder). Some examples of composites are:
Fibreglass
- Fibreglass is a composite:
- The matrix is a polymer.
- The reinforcement is glass fibres.
Concrete
- Concrete is a composite:
- The matrix is a cement.
- The reinforcement is a sand and gravel mixture.
Carbon fibre
- Carbon fibre is a composite:
- The matrix is a polymer.
- The reinforcement is carbon fibres or carbon nanotubes.
