| Description | So far we have discovered that manually sheared steered fibre hybrid laminates can improve the buckling resistance and strength of panels under in-plane compressive loading and we now have strong numerical evidence to show that the technique can be used to enhance the buckling performance of thin-walled cylinders (potentially useful in manufacturing rockets). These findings were made possible by the development of novel software able to predict realistic steered fibre patterns. The software is also essential in guiding the practical manufacture of steered fibre sheets and we have used it to demonstrate a method of manufacturing actual steered panels. The work on flat panels has been published in two journal papers and two conference presentations. The grant has also supported the development of new modelling and characterisation techniques focusing on the forming mechanics of engineering fabrics. Two journal further papers have been published on this work, one of them a new collaboration with Italian researchers interested in generalised continuum mechanics. The modelling work demonstrates the importance of in-plane bending and torsional stiffnesses on the shear kinematics and wrinkling behaviour of engineering fabrics during forming (these stiffnesses have been largely ignored in previous investigations). The experimental characterisation work introduced a novel technique to mitigate wrinkling during shear characterisation, a technique that significantly improves the accuracy of the commonly used uniaxial bias extension test |

| PI Contribution | We are partners to the main EPSRC grant (EP/P021573/1) led by Dr Philip Harrison at the University of Glasgow. So far, we contributed to the manufacturing knowledge of 2D and 3D preforming. we will soon develop novel fibre architectures for steered fibre laminates. |
| Collaborator Contribution | Dr Harrison and his team have been developing computational models for steered fibre laminate performance, namely in buckling mode. This work has provided us with adequate knowledge for designing novel fibre preforms. |
