Description
An organic olefin-based thermosetting dicyclopentadiene (DCP) resin, C10H12, commercially available in Japan as TELENE® from RIMTEC Corporation, has a viscosity less than one tenth of that of the CTD-101K® epoxy resin. The TELENE® can tolerate larger strains than CTD-101K® and can have a higher heat capacity by mixing it with high heat capacity powders. Using the TELENE® as the impregnation resin is expected to reduce the number of quench training of Nb3Sn magnets. The viscosity, heat capacity, thermal conductivity, and other physical properties of TELENE® with high heat capacity powders were measured in this study. To confirm the irradiation effect of the pure and mixed TELENE®, the gamma-ray irradiation up to 25 MGy was performed at room temperature using a Cobalt-60 source at the Takasaki Advanced Radiation Research Institute, Japan. The flexural properties of the pure and mixed TELENE® were measured before and after the gamma-ray irradiation and compared to that of CTD-101K®.
