Abstract
In this paper, fibre epoxy composite specimens are prepared by hand lay-up method with stacking sequences (04/±452)s. Five specimens are prepared with the same dimensions and named as S1, S2, S3, S4, and S5. These specimens are tested for impact analysis using a drop-weight apparatus (DWA-Ceast9350) at energy levels of 25, 30, and 35 J, followed by tensile testing using a universal testing machine (Dak9103). The damaged areas of the impacted specimens are examined by digital image processing, numerically simulated ABAQUS software, and scanning electron microscopy, followed by tensile strength results. The results of the experiment reveal that when the impact energy increases, the damage area increases, the tensile strength decreases, and the cracks formed during impact are shown in scanning electron microscope imaging. The homogeneity and isotropy of the composite are identified by the Feret ratio and circular shape factor.
