Micro and nanomechanical testing of ceramics and composites - Dr Oriol Gavaldà Diaz 

New structural materials rely on the micro- and nanoscale design of their
microstructure to achieve the desired performance. A classic example of this can be found in long fibre reinforced composites used in aerospace, automotive or energy generation, where fibre-matrix interfaces are customised to achieve the desired strength and toughness. However, understanding the properties of these nanoscale features and their effect to the bulk failure is challenging.
In this talk, I will be presenting the small-scale testing (from micro to nanoscale) that we have developed over the recent years to better understand the failure of materials and allow the design of new microstructures. I will show how we are able to test a variety of composites and ceramics and obtain nanomechanical properties such as toughness, strength and friction of fibre-matrix interfaces.
