Abstract:

The following aspects of fatigue behavior of reinforced plastics composite materials were studied. 1 Investigation of damage propagation in cantilever beam specimens of different composite materials subjected to fatigue cycle of complex stresses. The studies included residual strength determination, ultrasonic examination and microscopic inspection. 2 Investigation of damage in different composite specimens under tension fatigue stress cycling. The studies were residual strength determination, ultrasonic inspection and scanning electron microscope examination. 3 A study of cummulative tension fatigue damage mechanisms under programmed loading and analysis for glass cloth composites.
