Double-sided reinforcement is more effective than single-sided reinforcement
Increasing the number of CFRP layers and their elastic modulus yields the most significant improvement
Elevated temperatures greatly affect the mechanical properties of the reinforced steel plates
The effective bonding length and the stress intensity factor amplitude at the crack tip increase with temperature
