Description
The effects of temperature on the fatigue and low velocity impact (LVI) behaviors of adhesively-bonded single-lap joints (SLJs) composed of a pultruded E-glass/polyurethane composite bonded to 5052 aluminum and A36 steel were investigated. The fatigue behavior was studied via the evaluation of the F-N and stiffness degradation diagrams at load levels between 50% and 80% of the ultimate static load and temperatures between 0°C and 75°C. Fatigue life was found to decrease with increasing temperature and was independent of adherend material. Adherend material and load level did not have a significant effect on the stiffness degradation behavior. The LVI behavior was studied at temperatures between -20°C and 120°C at an impact velocity of 1 m/s with a drop mass of 7.19 kg. The joint performance was evaluated at initial failure and overall response. The LVI responses exhibited material dependencies at temperatures below Tg and temperature dependencies near and above Tg.
