An investigation on the residual strength of silane-modified clay/epoxy nanocomposites.
Residual strength tests were performed on unmodified and silane-modified clay/epoxy nanocomposites by applying various cyclic stresses. The residual strength of silane-modified samples proved to be greater than that of unmodified samples, irrespective of the cyclic stress level. For clay/epoxy nanocomposites, cyclic stress proved to have little effect on residual strength. Fatigue strain energy was improved by the silane modification of clays because of an increase in the toughness and interfacial strength between the clays and epoxy matrix.
