Abstract
A large residual stress due to the non-uniformity of temperature in the cooling process during its molding may develop inside the thermosetting-resin which has a two-dimensional spread. And, when there is a temperature difference on both surfaces in contact with the metal die, not only a residual stress but also a large warp is produced in the molding.
This present paper discusses the effect of viscoelastic behavior on residual stress and deformation of thermosetting-resin strip constrained warp with metal die by single-side quenching. The viscoelastic behavior of thermosetting-resin was expressed by simple mathematics including two modul in the range of glassy state and rubbery state, glass transition temperature and time-temperature equivalent factor. The residual stress and deformation by quenching was calculated by the fundamental equations derived from the theory of linear-viscoelasticity. And the effect of viscoelastic behavior on residual stress and deformation of this quenched strip was discussed.
