A composite material can be defined as a reinforced polymer or a combination of a resin matrix and a reinforcement, which combine to give excellent physical properties.
The term ‘composite’ is used to describe a multitude of materials, including resins such as Epoxy and reinforcements such as glass, carbon or aramid fibres.
Composites can be further categorised. Those supplied in a ‘B’ staged condition, in which the resin is semi-cured such that the composite can be molded under heat and pressure to the required shape and those supplied as a ‘C’ stage or fully cured composite. ‘C’ staged composites are usually taken to be rigid composites, but those using a flexible resin system can be supplied as a flexible material, in roll form.
