Research Abstract

Constitutive relations of thermosetting resin during curing process were formulated on the basis of experimental results of viscoelastic deformation and volume shrinkage for various temperature conditions. Internal stress of resin models induced by curing process were analyzed using formulated constitutive relations.
1. Material properties of thermosetting resin during curing process
(1) Volume shrinkages were experimentally measured during curing process under various temperature conditions.
(2) High temperature curing resulted in rapid and large shrinkage.
2. Constitutive relations of thermosetting resin during curing process
(1) Creep deformations were experimentally measured during curing processes under various temperature conditions.
(2) Experimental creep deformations were formulated by using non-linear viscoelastic models.
3. Estimation of internal stress of resin models
(1) Large internal stresses were induced by high temperature curing for two-layered composite models of the resin and metal plate.
(2) Viscoelastic analysis gave better results than elastic analysis for the estimation of thermal deformation of the model.
(3) Non-uniform temperature distribution induced large internal stresses for the resin n block of molding cavity comparing uniform temperature conditions.
