In order to study the influence of adhesive fillet radius on bond strength as well as notch-stress t-shaped specimens of Norway spruce wood (Picea abies Karst.) bonded with a rapidly curing epoxy adhesive were tested in tension. In general, increasing tensile strength was observed with increasing fillet radii and web thickness. The effect of small fillet radius was more pronounced for thin webs. Highest notch-stress reduction was found for samples of small fillet radii and thin webs.
