Low-energy impact damage was induced in particulate-filled glass-epoxy laminates by means of a falling weight device, and the damage features were studied by sectioning through the impacted area. The polished sections were studied by optical and scanning electron microscopy to obtain comparative qualitative information about the effects of several different mineral fillers : solid glass beads, hollow glass microspheres, quartz, alumina trihydrate and mica. Approximately 8.5 mm thick laminates, with and without fillers, were impacted at various energies up to 43 J. At the lower impact-energy levels, the damage in the unfilled laminates in most samples was typically transverse matrix cracking, at some distance below the point of impact. Transverse and interlaminar cracking was more extensive in filled than in unfilled laminates. The type and distribution of the damage features are discussed in terms of the properties of the filler particles, and of the stress distributions involved.
