Lifetime estimation of epoxy based composite materials on irradiating with gamma radiation for shielding applications

The extensive application of polymer composites in the ionizing radiation conditions leads to durability issues where performance for a long run under the radiation environment is related. For the products, such as space applications; it is expected to have about 20 to 30 years of durability. In the...
