摘要：
Carbon/glass hybrid composites have shown great potential in industrial applications. The infrared radiation characteristics of carbon/glass hybrid composite laminates and two types of non-hybrid composites under low velocity impact were studied experimentally by infrared thermography. The damage mode of the laminates was determined after impact by visual, ultrasonic C-scan and optical microscopy, and then the time series variation and temperature distribution characteristics of the thermal map sequence were analyzed to characterize the heat dissipation effect during the impact. Results show that the infrared thermography is highly suitable for monitoring the damage process of fiber reinforced composites under low velocity impact, and that the relationship between the monitoring characteristics and the damage modes can be established through the thermal map sequence. It is also found that the interlaminar hybrid of carbon glass fibers can effectively improve the anti-delamination ability of carbon fiber reinforced polymer (CFRP) composites. With the increase of impact energy, the anti-delamination ability becomes more obvious. After impact, carbon glass hybrid composites show both larger surface damage and smaller delamination damage with better damage tolerance. © 2023 Beijing University of Aeronautics and Astronautics (BUAA).
