- Abstract:
- In order to study the effect of carbon powder dosage on carbon fiber reinforced polymer (CFRP) tendon piezoresistivity, five groups of CFRP tendons with different carbon powder dosage(0%, 2%, 4%, 6%, 8%)were produced, and the resistancestrain behavior was studied through axial tensile test. The results show that carbon powder reduces the initial CFRP tendon resistance, CFRP tendon has good linear relationship between resistance change rate and strain at low stress level, the linear correlation coefficient is above 0.92, the sensitivity value is 20 to 30. The ultimate strain of CFRP tendon is 3% to 5%, the maximum resistance rate is 35% to 60%. The effect of carbon powder dosage on CFRP tendon sensitivity is less at low stress level.
