Introduction In general, the cure of thermosets such as unsaturated polyester and epoxy resins, proceeds by transformation from liquid to rubber (gel) to glass to form a rigid cross-linked structure [ 1 , 2 ]. The cure

and vitrification. Gelation is the incipient formation of a cross-linked network, and it is a most distinguishing characteristic of a thermo-set. Gelation does not usually inhibit the process of curing, and it cannot be detected by techniques which are
