On the effects of loading velocity in T-peeling and lap-shearing strengths of FRP

Mechanical properties in T-peeling and lap-shearing of FRP under dynamic load obtained by using the one-bar method are reported. Comparing these with mechanical properties under quasi-static load, positive velocity dependence is clarified in T-peeling strength and lap-shearing strength vs. loading velocity relations. The effects of fiber orientation (reinforcement combination) and of the nature of the fiber itself on the strengths of specimens are also clarified.
