Compression of fibre composites

Fibre composites have an unveiled potential in compression. Improvements in their matrix, fibres, interfaces and architecture can prevent early instabilities that cause failure in compression. In my current project we are developing the next generation of fibre composites, with highly improved compression resistance.

Strain rate dependency of materials

The mechanical response of materials can be affected by how fast the loads are applied, how quick deformation occurs. For instance, polymers tend to be stronger at higher speeds of deformation than at quasi-static regime due to their viscoelastic nature. In my research, I investigate how different materials behave at quasi-static and at dynamic regimes. This information is later translated into mechanical models to help engineers to design real components.

Ageing of composite materials

My research is oriented to the study of composite materials for underwater and aerospace applications. During service conditions these composites will be subjected to humid environments. My current investigation aims to develop a constitutive model able to capture the effects of water uptake upon the strain rate dependent properties of composites. Previously, in my master thesis, I investigated the degradation of fracture toughness of an epoxy resin due to hygrothermal aging.
