Primary Research Theme: Materials and Structures
Research Group/Lab: Structures and Composite Materials

The understanding of composite materials and their structures requires an in-depth knowledge of basic material behaviour. Knowledge of fibre and resin behaviour is essential for understanding the intricacies of composite manufacturing processes. This must be accompanied by stress, strain and failure analysis in both the static and fatigue regimes. Finally, designs must be manufactured and tested. Here is where design optimization helps to achieve the final goal: a successfully designed composite structure. The 91社区 Structures and Composite Materials Laboratory thus explores the design of composite materials and their structures "From Start to Finish".
