Vacuum Assisted Resin Transfer Molding (VARTM) is a promising affordable technique for producing composite integral armor (CIA) and thick-section composites for army relevant applications. Among several constituents, the CIA uses S2-glass/epoxy and/or S2-glass/vinyl ester (VE) composites in its construction. The S2-glass reinforced composite serves the function of providing ballistic protection and load beating due to the flexural loading caused from the movement of the vehicle over various terrains. The S2-glass reinforced composite is subjected to different levels of delamination when subjected to projectile impacts. The present study focuses on - a) the repair of S2-glass/epoxy composites subjected to a clean-perforation type of ballistic impact scenario, and b) post-repair flexural response of the composite panels. Simple repair solutions involving the use of different plugs reinforcing the damage (12.7 mm, 25.4 mm and 38.1 mm (0.5" l" and 1.5") clean perforations) have been implemented in S2-glass/vinyl ester laminates. Static and fatigue tests were conducted under flexural loading. The effects of implementing the repair strategies on the flexure performance have been reported.
