Thermal and Dielectric Properties of Epoxy Resin at Low Temperatures after Irradiation and H2 Permeation of Fibre Composites at Room Temperature

Measurements of thermal conductivity, specific heat, and dielectric properties of an epoxy resin after electron, gamma, fast-neutron, and thermal-neutron irradiation are presented. The experimental results show the influence of the different types of radiation on the typical amorphous behaviour of the thermal properties. The H2-permeation rate for two types of carbon-fibre-reinforced plastics are presented.
