Abstract

Instrumented indentation and confocal microscopy were used to characterize the surface mechanical response of polymeric materials. Viscoelastic behavior was measured using instrumented indentation. A model based on contact between a rigid probe and a viscoelastic material was used to calculate values for creep compliance and stress relaxation modulus for two polymeric materials, epoxy and poly(methyl methacrylate) or PMMA. Scratch testing was performed on these materials with various probes under a variety of conditions, and confocal microscopy was used to characterize the resulting deformation. Relationships between viscoelastic behavior, scratch damage and appearance are currently being explored using these methods along with finite element modeling.
