This paper has presented an experimental study of quasi-static compressive and tensile loading of cutout hole on multi-layer of Kevlar-29/epoxy-Al2O3laminated composite. The experimental procedure has been developed to study the performance of (50%, 55% and 60%) volume fraction (vf) and (0o/90o and +45o/-45o) fiber orientation angle effects of these composites under quasi-static compressive and tensile load using a servo-hydraulic testing machine. It was concluded that the maximum load bearing capacity increases as volume fraction increases in tensile test. While, the maximum load bearing capacity increases with the decrease of volume fraction in compression test. Hence, from the results obtained it can considered the 55% volume fraction of composite panels is a good value for tensile and compression applications
