  • J191026 A Trial Production of Epoxy/TiO_2 Nanocomposites to Improve Ultraviolet Light Resistance

抄録

This study carried out a trial production of Epoxy/TiO_2 nancomposites to improve ultraviolet light resistance. Two kinds of TiO_2 particles with a diameter of 30nm and 270nm were dispersed in the epoxy resin and the ultraviolet light resistance was evaluated based on UV irradiation tests, tensile tests, and SEM observations of specimen surfaces and fracture surfaces. As a result, elongation at break of epoxy resin and epoxy/TiO_2(270nm) composite decreased after UV irradiation although that of epoxy/TiO_2(30nm) composite remained unchanged. Epoxy/TiO_2 (30nm) composite likely to suppress the embrittlement of surface layer caused by UV irradiation, and tend to reduce the crack initiations which deteriorate strength properties.
