抄録

The mechanical properties of epoxy resin are experimentally investigated under various curing temperature conditions using a rheometer of double cylinders. The properties are represented by a viscoelastic model of three elements and the values of the elements are determined on the basis of experimental results. The shrinkage of the resin is measured using dilatometer under various temperature conditions. The change of shrinkage over time is investigated. Internal stress under curing conditions is numerically calculated using the finite element method including experimentally determined material constants of the resin. The analysis is applied to a two-layered model composed of epoxy resin and aluminum alloy and a model of resin poured into a box. The deformation of the two-layered model under curing conditions is accurately predicted based on experimental results. The internal stress in the poured-resin model is influenced by the temperature of the resin. High curing temperature results in large internal stress.
