A novel method for measuring the uniaxial mechanical properties of an epoxy resin during polymerization

摘要

AbstractA new sample configuration for measuring tensile mechanical properties during cure is described. The method utilizes a soft rubber membrane to physically constrain a sample in a uniaxial geometry. Using this method in combination with a Dynastat mechanical spectrometer, it was possible to follow the polymerization of an epoxy resin from the liquid to the glassy state in a single experiment. The results of a uniaxial dynamic mechanical characterization of a curing epoxy resin are presented.
