<i>Ex-Situ</i> Study of Polymeric Syntactic Foams Mechanical Response Under Compression Loading: Effects of Foam Microstructure Using Microtomography Techniques

Syntactic foams are widely used in many impact-absorbing applications and can be employed as sandwich core. To improve their mechanical performances, these composite sandwich structures have to be modelled. This approach requires the characterisation of the foam behaviour. Moreover, the microstructure of the syntactic foam has an influence on its macroscopic behaviour; the foam density, the diameter of the porosities, their distribution in the material have to be taken into account.
