As fillers are traditionally designated those finely divided solids which are added to a polymer matrix in relativly large amounts to modify its properties and/or to reduce the price of the resulting compound. Generally a filler material is stiffer than the matrix and depending on their origin, shape and treatment fillers are reinforcing or not. In this presentation the authors will briefly review the characteristic mechanical effects on small strain behaviour, structure and time‐dependent properties of filled polymers stemming from the addition of more or less “spherical” fillers such as calcium carbonate, quartz flour, silica or glass spheres. The effect of such fillers on yield deformation, the nature of possible damage proceeding fracture and their effect on the toughness of particulate filled thermoplastics and thermosets will be discussed in more detail.
