An Investigation of Fatigue Behavior of Reinforced Plastics for Primary Aircraft Structures.
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. (Author)
