Abstract
Microfilled composites were fabricated by curing with visible light. Diametral tensile strength (DTS) of the microfilled composites was measured, and the effects of several factors on DTS were examined. The factors were silane coupling agent concentration, silica content, the composition of matrix resin, and curing time. Silane coupling agent concentration and the interfaces of the microfilled composites were mainly investigated. IR and SEM were used for analysis. Silane coupling agent concentration was the factor most affecting DTS, and maximum DTS was observed at 5.0 wt% concentration. In addition, DTS of the microfilled composites had linear relationships with silica content and curing time.
