Radiation Damage to Plastics and Coated Fabrics-1,
Abstract
Various plastics, plastic laminates, fabric laminates, glass cloth laminates and a fabric were irradiated in October 1955 using the Ground Test Reactor at Convair-Fort Worth. The specimens were subjected to an average integrated fast-neutron flux of 6 x 10 to the 14th power nvt, an averagfe integrated thermal-neutron flux of 6 x 10 to the 13th power nvt, and an average integrated gamma flux of 5 x 10 to the 16th power gammas/sq cm. After irradiation, tests were performed on irradiated and control samples of detect changes in physical properties resulting from the irradiation. The properties which showed most change were tensile strength, elongation, compressive and flexural strength, hardness, and tear strength. However, a trend i the changes was not discernible; for example, in some cases tensile strength was increased, and in samples of the same type materials, a decrease was noted. The samples displayed few changes in thermal expansion, dielectric constant, surface resistivity, and loss tangent. (Author)
