Artykuł opisuje badania wpływu kształtowania końca skleiny stal-kompozyt FRP na nośność złącza. Badano wpływ zmian geometrii końca złącza na zachowanie się osiowo obciążanych, płaskowników stalowych wzmocnionych obustronnymi nakładkami z taśm węglowych, o różnej długości wiązania. Zniszczenie skleiny na granicy stal-klej było dominujące wśród postaci zniszczenia dla przyklejonych do stali taśm CFRP. Przedstawiono wyniki badań, które pokazały, że zmiana geometrii końca spoiny może znacząco podnieść nośność złącza. Opisano wnioski i przedstawiono plan dalszych prac nad wzmacnianiem elementów stalowych taśmami CFRP.

Article describes experiments on the effect of steel – FRP bond end shaping on bond strength. The influence of changing the bond end geometry on behavior of axially loaded steel elements reinforced by CFRP double patch joints with varying overlap length was analyzed. Bond failure at steel-adhesive interface was dominant failure mode. The test results showed clearly that geometry change of the bond end of strengthening CFRP plate and adhesive in composite plate region can significantly increase bond capacity. Conclusions and plan of further works on CFRP strengthening of steel elements were described.
