Characterization of impact properties and damage process of glass/epoxy composite laminates

摘要: This paper investigates the responses of glass/epoxy composite laminates subjected to impact loading. It presents a new technique characterize properties and correlate them with damage process laminates. The technique, called energy profiling is based on instrumented tests least-squares method. gives specific definitions penetration perforation thresholds also defines range quantifies absorption efficiency primary modes in can be correlated by using technique. advantages this analyze experimental data obtained from are demonstrated investigating various impactor sizes, laminate thicknesses, fiber orientations, s...
