Abstract

Variation of thermal conductivity and specific heat of a general-purpose unsaturated polyester during cure was investigated experimentally. Measurements were made on the cured, partially cured, and uncured samples, and the results are presented. Both thermal conductivity and specific heat of the cured samples increase nearly linearly with increasing temperature. Effect of degree of cure on the thermal properties is evident during the earlier stages of cure.
