Present study aims to investigate quasi-static indentation (QSI) behavior of fiber reinforced hybrid composites in order to develop basic understanding of low velocity impact events. The goal of QSI tests from this study is to explore energy absorption, and load carrying capacity incorporating two and three different combinations of fibers. Major reinforcing fibers were selected as Kevlar with twill weave, carbon and S-glass fibers with plain weave for designing of hybrid composites. Failure modes and extension of damage mechanisms were characterized by observing the surfaces of the indented samples, and damage assessment was identified through the thickness by the cutting of test samples. The results from this study showed that failure mechanisms in hybrid samples were significantly affected by stacking sequence of the fibers as well as fiber types.
