Abstract
A missing element of paper aging research is a description of mechanical performance with aging. Tensile strength cannot be predicted directly from DP measurements, and existing models do not represent the effects of aging on strength and stiffness. The primary aim of the present work is to characterize changes of mechanical properties, such as tensile response and dimensional stability, with aging and to develop time-dependent models to describe the behavior of paper components in stamp laminates. This includes understanding the underlying mechanisms of aging, such as changes of fiber properties or inter-fiber bonding, which lead to degradation. This research evaluates the effects of thermal aging on the properties of two different papers using tensile testing to characterize the tensile strength and initial stiffness, along with measurement of the equilibrium moisture content at 50% RH.
