摘要：

Residual stresses arising from the curing process in a three-dimensionally constrained epoxy resin have been determined experimentally by a strain-gauge method. The results were analysed using the theory of incremental elasticity for an ageing, linear thermoelastic material subjected to dimensional constraints. It was found that large residual stresses developed in three-dimensionally constrained epoxy resins and that, by modifying the cure schedule, the internal stresses could be reduced. The bulk behaviour of the epoxy resin under volumetric constraints was also investigated. Values for the bulk modulus of the epoxy resin were calculated from the results at temperatures above and below the glass transition temperature of the resin. © 1990.
