Cure kinetics meaning

WebThe cure kinetics models developed in the literature for the 8552 resin system are usually phenomenological and do not reveal the actual mechanism taking place during curing [4, 6-11]. The cure shrinkage of epoxy resins and composites were either measured directly by volumetric dilatometer [12-15], by density change techniques [16-18], by ... WebCure kinetics, therefore, is necessary to quantify the extent of chemical reaction or degree of cure for the given cure cycle. It is also important to predict resin viscosity during mold filling, which may change due to chemical reaction. There exists a heat transfer between the mold and the composite during mold filling and resin cure.
