Mapping with the Image Processing Method of Damage Regions with Respect Composite Laminates Subjected to Low Velocity

Abstract

In this study , uni-directionaly reinforced laminates that arranged e-glass / epoxy composite samples in the form [ + 45 / -45 / 90/0 ]s and [ + 45 / -45 / 90/0 ]2s was applied low-velocity impact tests at impact energies of 10, 20 and 30 J has been obtained 8 and 16 laminated sample. Low-velocity impact tests were performed with the drop weight test device. Low-velocity impact damage was created on the samples depending on the different impact energies as a result of experiments conducted with hemispherical various impactor. The impactor mass was 6.350 kg. Digital imaging process method was applied images of the samples subjected to impact damage and damage maps for each damage zone were extracted. Also, change graph of damage area depending on the impact energies has been omitted. Changing damage zones were extracted. Also, change graph of damage area depending on the impact energies has been omitted.
