熱硬化性樹脂の硬化過程における粘弾性特性と内部応力

抄録

The internal stress of thermosetting resin generated during curing process was analyzed by using a viscoelastic model. The changes in viscoelastic properties in the curing process were measured experimentally by a rotating rehometer. The viscoelastic constitutive relations in the curing process were formulated by the three elements spring dashpot model. The deformation of two layered resin and metal in the curing process was investigated experimentally. The results were compared with F.E.M. analysis on the basis of the viscoelastic relations and shrinkage model of the resin. The viscoelastic analysis gave more realistic results than the elastic analysis.
