Research on ultrasound propagation characteristics and quantitative evaluation of sub-millimeter foreign bodies in CFRP based on finite element simulation
To address the critical issue of sub-millimeter Polytetrafluoroethylene (PTFE) foreign body inclusions inadvertently introduced during the manufacturing of Carbon Fiber Reinforced Polymer (CFRP), this study investigates the underlying detection mechanisms and quantitative evaluation methods using ultrasonic testing tec...
