Experimental Studies of Glass Reinforced Aluminum (GLARE) Bolted Joint

GLARE laminates with outstanding impact resistance, high fatigue resistance and a number of excellent performances are combined by ductile aluminum layers and high strength FRP layers. An experimental program was conducted to estimate the influence of geometric parameters, ply orientation and tightening torque on the performances of GLARE bolted joint. The study showed that the parameters of GLARE bolted joint have intrinsic properties of metal bolted joint and composite bolted joint. The design threshold values including of geometric parameters, ply orientation and tightening torque were given.
