One way to strengthen the mechanical properties of plastic materials is to add nanoparticles, forming that way a composite material. A detailed structural study by neutron scattering, coupled with mechanical tests, of polystyrene reinforced with silica particles has been performed at the Laboratoire Léon Brillouin (LLB) at CEA Saclay. It shows the importance to control the concentration and distribution of particles entering in the composition of the material. This model study has many applications, especially in the tire technological domain. |
