Abstract

In this research, THERMAL PROCESSes for removing the RESIDUAL STRESSes from POLYCARBONATE sheet are evaluated using extensive experiments. In each step, by making suitable alterations and modifications on the heating cycle parameters, annealing operations are performed on the samples during a try and error process. Finally, appraising the obtained results, a modified thermal cycle is presented which can remove the RESIDUAL STRESS from the POLYCARBONATE sample, while reducing the time and cost of the annealing process. According to this process, the specimen temperature is raised to 100oC at the heating rate of 20oC/h. The samples are kept at this temperature for 3 hours to become dried and then, the heating is continued up to glass transition temperature at the rate of 5oC/h. Then, the specimens are heated at the rate of 1oC/h until temperature of Tmax= 156oC. After reaching this temperature, the samples are cooled immediately, and the cooling rates are same as the heating rates.
