Damage tolerance related to the damage area of impacted carbon/epoxy composite laminates
JOURNAL OF COMPOSITE MATERIALS(2023)
摘要
This study aimed to analyze the damage tolerance of a carbon/epoxy composite laminate (AS4/8552) impacted at low velocity, relating residual strength values with the impact energy and delaminated area. AS4/8552 laminated plates [0 degrees(3)/90 degrees/+/- 45 degrees](S) were submitted to low-velocity impact tests with three energy levels: 30 J, 45 J and 74 J. Next, the test specimens were analyzed by X-ray computed tomography to check for cracks and delaminations, and compression after impact (CAI) tests conducted to assess their residual strength. The results indicate that above the minimum energy level of low-velocity impact to cause damage, the residual strength of the laminate may be related to the delaminated area.
