A major trend in today's society is the development of new, more efficient and/or larger structures. Composite materials based on long aligned fibres are increasingly used in large structures such as wind turbine blades, aeroplanes and ships. This striving for larger and more efficient structures creates a constant push for materials science to develop new materials with enhanced properties (moving the limits of the materials) and to develop better, more precise and reliable design methods and criteria (moving the design limits).
The limits of materials properties can be increased by materials development, by understanding how composite materials work at various length scales, e.g. understanding the interplay between properties of fibres, matrix and the fibre/matrix interface through micromechanical modelling and microscale experiments.
Design limits, e.g., criteria for material failure and lifetime predictions, can be expanded by developing and validating improved models for the critical limit states, e.g. the onset of fatigue failure under multiaxial stress state, the use of damage tolerant design approach and the use of more advanced modelling tools such as cohesive zone modelling.
The limits of composite materials and structures were the theme of the Symposium. The presentations covered the challenges of identifying and moving the experimental and modelling limits.
