Impulse viscoelasticity: a new method to study polymerization of thermosets

The technique of impulse viscoelasticity, in combination with incremental linear elasticity, is presented for monitoring the mechanical and rheological changes which occur during the solidification process. The technique is specifically applied to the curing of an epoxy resin (e.g. Epon 828). For su...

Description
Summary:The technique of impulse viscoelasticity, in combination with incremental linear elasticity, is presented for monitoring the mechanical and rheological changes which occur during the solidification process. The technique is specifically applied to the curing of an epoxy resin (e.g. Epon 828). For such a system, the properties which can be measured as a function of the cure history are gelation time and temperature, equilibrium tensile modulus, cure stress and shrinkage, steady state elongational viscosity, mean relaxation time, thermal expansion coefficient, glass transition temperature and dynamic mechanical properties. . 9 ref.--AA
