A structure comprising a composite laminate having an edge (8); and an impact indicator (9) which is carried by the edge (8) and comprises a resin which fractures upon impact. The fracture provides permanent visible evidence of impact damage, for instance by cracking or byone or more pieces breaking off from the impact indicator. As well as providing such visible evidence of impact damage, the impact indicator may alsoprovide an element of impact protection. Typically the impact indicator (9) is formed from a resin which is more brittle and less strong than the material forming the composite laminate. For instance the material forming the composite laminate may be reinforced, and the resin forming the impact indicator may be un-reinforced.
