Abstract

Experimental studies were carried out on the curing behavior of unsaturated polyesters and epoxy resins. The latter were modified with three different fillers (CaC03. CaSi03, and glass powder) and their curing behaviors studied. Polyesters exhibited faster cure rates than the epoxy resins. The gel time of the epoxy resins decreased with the addition of fillers. Data indicated that the peak exothermic of these thermosetting resins increased when filled with glass powder. The hardness of the using mass increased with curing time. The of gel-hardness number as a quality control parameter has been suggested.
