An experimental study of circular cutout hole effect of Kevlar epoxy-Al2O3 composite under subjected to quasi-static compressive and tensile loading

الملخص EN

This paper has presented an experimental study of quasi-static compressive and tensile loading of cutout hole specimens of Kevlar-29/epoxy-Al2O3 laminated 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 tensile and compressive load using a servo-hydraulic testing machine.

The study was concluded that the ultimate load 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 have considered the 55% volume fraction of composite panels is a good value for tensile and compression applications.
