摘要

The material property changes of an acrylic multi-polymer after gamma irradiation are determined with respect to time and temperature. Empirical models are developed using a design of experiments approach. The effects of thermoforming on the aging behavior are examined. Experimental variables include irradiation dose level, aging temperature, and aging time. The models developed are used in conjunction with real time ambient temperature aging to derive Q_(10) factors for the material as defined in ASTMF1980.
