- Impact damage, especially at low velocities, is commonly viewed as one of the most severe threats to composite structures. This paper is the first to report the successful moulding of composite plates prestressed by randomly oriented discontinuous fibres, which is impossible to achieve by conventional (elastic) prestressing. Even at very low fibre concentrations, these plates demonstrate a notable improvement in impact capability (30% reduction in damage depth). The manufacturing flexibility and simple equipment requirements make this potentially very useful for collision-prone structures, such as plates or panels within marine environments.
