摘要：
The mechanical characteristics of the epoxy matrix found in filler reinforced polymer composites is important for determining strength and performance. Locally, property variations in regions surrounding fillers can influence the overall macroscopic composite response to loading. We investigate local nanomechanical stiffness of reinforced epoxy composites by using atomic force acoustic microscopy. The effects of tip shape on the contact mechanics at the epoxy interface are found to influence the reported results significantly and will be discussed in context of different tip models. The results have direct correlation to the effect of near-filler interphase regions and the long-term influence of environmental conditions on the polymer composites.
