Abstract
A micro mechanical study of Carbon/Epoxy composites with internally dropped plies has
been made using micro-moiré interferometry. The experimental results show that there is a stress
concentration region before the dropped ply. Micro cracks were initiated and propagated in this
region. Two failure mechanisms in the dropped ply region were observed.
