Testing and Evaluation of Composite Aerospace Structures-Challenges and Opportunities

摘要：

The increased use of composite materials in the structures of civil transport aircraft brings ever greater demands to reduce design, certification, manufacturing and operational costs. New simulation tools are being formulated to dramatically reduce the number of tests required during the design and certification of new aircraft, thereby reducing development time and cost. This is particularly challenging in composite materials that exhibit complex, interacting failure modes coupled with time and temperature dependent behaviour. In this paper, an overview is given of recent developments in simulation tools for composite materials and structures. Tools to simulate the effect of a range of defects and damage on the performance of composite structures are described. These include tools to assess fibre waviness and undulations, delaminations and disbonds, impact damage and residual strength. Simulation methods for the design and optimisation of repairs to composite structures, as well as methods to predict the energy absorption and crushing response of composite structures, are described.
