Bonded joints are key structural elements and for parts made from fibre reinforced polymeric matrix composites (FRC), these are preferred over mechanical fasteners such as rivets and bolts. Low velocity impact loading of structures is frequently encountered both in-service and during maintenance and when an object made from FRC is subjected to impact loading, the resulting damage is often quite complex in terms of both multiplicity and unpredictability of damage modes. If the structure involves bonded joints the complexity is increased further. Since the use of composite materials is continuously increasing in all type of structural components the impact threat can no longer be dealt with simplified design approaches and unrealistic in-service operating requirements. All the major commercial Aircraft manufacturers are looking at fibre polymeric composites as the material of choice for the future aircrafts, however, the poor understanding of impact Induced damage mechanisms necessitate the use Of generous safety factors for product design. This often results in offsetting the weight saving advantage promised by composite materials, which is a consequence of their higher in-plane specific modulus and strength. Hence, from both an academic and industrial point of view it is important to Increase the understanding of impact damage in bonded joints of composites.
