Popis:	It is of interest to determine the value of the state of cure of a thermoset and thus to correlate the state of cure with some properties of the material. In this study, the state of cure at time t is expressed by the extent of heat evolved from the overall cure reaction at time t as a fraction of the corresponding heat evolved after infinite time. Various sample sheets of Bulk moulding compound with polyester of given values of the state of cure are prepared. A numerical model enabled one to obtain the operational conditions necessary for preparing these samples. A correlation between the hardness of the sample and the state of cure is shown.
