Abstract

When simulating the curing process of composites, the specific heat of cured resin was often used as that of the resin during the whole process.This could cause great error in the simulation result.As the heat release of curing reaction, the specific heat of resin during curing was difficult to be measured.A hypothesis was presented that the specific heat of resin changed greatly at the gel point.Before that point the specific heat of uncured resin was linearly lessening to the value of cured resin, while after gel point the specific heat of cured resin was used.The simulation result was in good agreement with the experiment data.
