Description	Because composite materials have high specific stiffness and strength, their use in engineering applications is continuously growing. Poor impact performance is the major drawback for widespread application. Impact loads can be classified into three categories: low-velocity, high-velocity and hyper-velocity impact. Hyper-velocity impact involves projectiles moving at extremely high velocities, such that the local target materials behave like fluids. The stress induced by hyper-velocity impact is many times the material strength. Failures resulting from impact can be unpredictable and vary depending upon the material quality. Fibre-reinforced polymer (FRP) composites have been extensively used in aircraft, land vehicles and lightweight structures for a long time. Impacts upon composite structures cause characteristics such as matrix cracks, delaminations and fibre ruptures. Some common failure modes in composite structures are fracture, yielding, insufficient stiffness (deflection), buckling and fatigue, but delamination is the most common failure mode. It occurs in composite structures under impact loads due to regional contact forces. Book Name: Failure of Fibre-Reinforced Polymer Composites
