Effect of temperature gradients on cure and stress gradients in thick thermoset castings

摘要: The temperature gradient developed during casting of an unsaturated polyester for which the kinetics reaction and heat capacities, thermal conductivities, densities were known from earlier work was measured experimentally as a function time in thick compared with predicted values calculated mathematical model. Agreement excellent. castings sectioned sections examined by birefringence. These examinations show good agreement between cure residual stress gradient. This demonstrates that extent position can be transfer calculations if properties are is dependent upon developed.
