CFRP-Reinforced Steel Plate

Enhanced fatigue life at elevated temperatures

Using the novel adhesive GY34, this reinforced structure effectively reduces the stress intensity factor at the crack tip and improves the fatigue life of steel plates under elevated temperatures.

Advantages

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
