COMPOSITE COMPONENTS

A fibre-reinforced polymer component 202 is provided which comprises a main portion 204 comprising fibre-reinforced polymer and at least one surface and at least one raised feature 206 extending from said surface. The at least one raised feature 206 consists of non-reinforced polymer and is shaped to incur visually perceptible damage when the component 202 is subject to an impact with an energy above a predetermined impact energy threshold and to resist an impact with an energy below the predetermined impact energy threshold. The at least one raised 206 feature thus provides a clear visual aid as to when a component 202 has experienced an impact with an energy above the impact energy threshold. Because the raised feature 206 consists of polymer without fibre reinforcement, it is more fragile than the fibre-reinforced polymer main portion 204 and thus reduces the energy at which impacts may be detected.
