In the present study, quasi-static and dynamic bending behavior of CFRP (carbon fiber reinforced plastics) with soft epoxy matrix was investigated. CFRPs were fabricated with the soft epoxy matrix and a standard carbon woven fabrics. The carbon woven fabrics of 5 layers were laminated to be quasi-isotropic. The impact three-point bend testing machine based on the split Hopkinson pressure-bar technique was developed. The bending tests were performed by a universal testing machine for low deflection velocities, a cam plastometer for middle ones and the impact testing machine for high ones. The experiments reveal that the bending modulus of the CFRPs strongly depends on the deflection velocity.
