| Description | Interesting new experimental evidence on the rate dependent behaviour of through thickness reinforced laminated composites is emerging. This evidence is essential in providing the designers with critically important information absence of which could adversely affect the design. |
| Exploitation Route | Comparison against experimental results generated by other researchers. Input into procedures for calibration of models for simulation of delamination and its suppression via through-thickness reinforcement adopted or developed by other researchers. Exploitation of previously developed methodologies and capabilities in current and future projects where improvements are sought. |
| Sectors | Aerospace, Defence and Marine,Education,Environment,Manufacturing, including Industrial Biotechology,Transport |
| Description | The generated (at Oxford's Impact Engineering Laboratory) experimental data has been (and continues to be) used to support the development of macroscopic cohesive models for simulation of through-thickness reinforced laminated composites. These models are already been used to explore the limits in the design of new generation of hybrid fan blades for large civil aviation gas turbine engines designed and manufactured by Rolls-Royce. Three subsequent projects funded by Innovate UK as a part of ATI programme have involved the researchers and equipment developed during this project. This has yielded methodologies and capabilities which are in the process of being broadened to smaller length scales and uplifted to Technology Readiness Level 6 and are as such being intensively utilised by our industrial colleagues at Rolls-Royce plc. |

| Title | High-speed digital metrology |
| Description | The ability to use multiple high-speed digital cameras has yielded the development of DIC based algorithm for tracking of selected markers in 3D for displacement/velocity and strain measurements. The algorithm takes care of physical and digital noise by scale separation and motion blur by custom edge detection thus providing more accurate data for validation of newly developed simulation models. |
