Accelerated Aging Response of Carbon Composites Under Tension and Bending

摘要

An accelerated aging method was developed to evaluate losses in mechanical properties in carbon composite materials. Carbon fiber reinforced polymer (CFRP) composite coupons were tested under tension and bending to establish their strength and stiffness. After accelerated environmental conditioning reductions in mechanical properties in mechanical properties of CFRP were established, and preliminary calibration was carried out using natural degradation rate of CFRP materials. The maximum reduction in these values after accelerated aging was found to be 7%. The aged CFRP material followed a reduction rate that corresponds to a typical inverse exponential curve.
