Carbon Fiber Reinforced Polymer (CFRP) faces limited industrial application due to their complex fracture behavior, complicated reliability and product life prediction, despite excellent properties. This study aimed to understand CFRP fracture mechanisms and identify critical factors. Constituent component properties were evaluated, and reliability was analyzed using Weibull distribution and detailed fracture surface analysis. The interface exhibited the lowest reliability, proving the most critical factor in CFRP fracture. These findings provide crucial data for CFRP fracture prediction and contribute to future reliability and lifespan prediction research.
