Interfacial Integrity of Carbon Fiber/Epoxy Matrix Interface Under Loading Conditions

In this chapter, molecular dynamics (MD) simulation is used to investigate the molecular interactions and behaviors of carbon fiber/epoxy interface under different loading conditions, including constant velocity, constant force, and cyclic loading conditions. The simulation results provide molecular insights into the structural and property variations of fiber/matrix interface under different loading conditions, which contribute to the understanding of interfacial degradation mechanism and the prediction of long-term performance of CFRP composite during intended service life.
