The CMRL studies composite mechanics with experimental testing and observation through micromechanical failure mechanisms as well as computational analysis. The Laboratory studies and replicates the mechanics of resin development creating new prepreg design concepts. These studies allow the design of new resin and prepreg systems meeting future needs for our customers.
Examples of mechanics research activities:
- Micromechanics of composite/neat resin including experimental mechanics and computational analysis.
- Study on Prepreg permeability for OOA cure material systems.
- Mechanical testing frame
- Finite element modelling(FEM)
- Digital image correlation(2D/3D DIC)
