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