This study aims to investigate the impact of delamination defects on the low-velocity impact behavior of thermoplastic composites. Specimens with different embedded delamination materials were manufactured and tested, showing that the maximum contact force of specimens increases with the increment of the delamination diameter.
In this study, it is aimed to reveal the effect of deficiencies that may occur during thermoplastic production stages which affects both the low-velocity impact behaviour and mechanical strength of the composite materials. To investigate the low-velocity impact performances of thermoplastic composites with embedded delaminations, specimens were manufactured without delamination materials and by using different embedded delamination materials. Two different delamination diameters were also used so as to investigate the delamination diameters on the impact behaviour of composites. All specimens were subjected to low-velocity impact tests at different energy levels ranging from 10 to 50 J. From the test results, the maximum contact force of the specimens increases with the increment of the delamination diameter.
