The fiberglass-reinforced polymer is the most widely used composite because of its lowrncost and easy availability in the market. Fiberglass reinforced polymer is used for structuralrnand semi-structural body parts of the automotive. During services, crack is the mostrncommon defect in a structure and cracked composite laminate is subjected to dynamic loadrnand the vibration of the cracked laminate has a significant effect on the failure of thernstructure. A crack on a laminate reduces the stiffness of the structure and the change ofrnstiffness affects the vibration properties of the laminate. During a change in vibrationrnproperties of the laminate resonance will occur and that causes catastrophic failure. In thisrnstudy, the free vibration analysis, particularly the natural frequency of edge cracked glassrnfiber reinforced polymer laminate using Analytical, Numerical by using Abaqus softwarernand Experimental analysis was studied. Specimen were prepared using a vacuum baggingrnassisted hand layup method. ASTM E756 is used for free vibration analysis. Experimentsrnare conducted using unidirectional [04]s and quasi-isotropic [0,90,45, -45]s laminatedrnbeam with different crack introduced by a hacksaw. The effect of crack depth and crackrnlocation on natural frequencies of unidirectional [04]s and quasi-isotropic [0,90,45, 45]laminatedrnrnbeam investigated for a cantilever beam. Results showed that the naturalrnfrequencies were different for unidirectional laminate and quasi-isotropic laminate and itrnindicates the vibration properties of composite material depend on fiber arrangement. Forrnboth UD and QS laminate crack decrease the natural frequency. From the analysis thernnatural frequency decrease for an increase of crack depth. For both UD and QS laminatesrnthe location of the crack affected the natural frequency. The effect of crack depth and crackrnlocation on the change of the natural frequency showed the same trend in all the threernmethods.
