EFFECT OF VIBRATIONAL STRESSES ON THE RESIDUAL SHORT-TERM STRENGTH OF GLASS FIBER REINFORCED PLASTICS ( GFRP ) LAMINATES ( EINFLUSS VON SCHWINGBELASTUNGEN AUF DIE REST-KURZZEITFESTIGKEIT VON GFK-LAMINATEN )

Description of test program and presentation of its results in tables and curves. It has been shown that test specimens in longitudinal test showed no regular connection, when subjected to tensile fatigue stresses, between the static crack formation stress and the residual strength. The longitudinal test specimens can in some cases be subjected to dynamic loads far above the static crack formation stress without loss of strength. In the case of diagonal test specimens however, tensile fatigue loading with higher loading cycles ( N greater than 10 to the 4th power ) above the static crack formation stress is not possible. No crack formation was observed when a longitudinal test specimen was subjected to compressive fatigue stress. In this case damage is caused by delamination.
