RESUME OF FATIGUE CHARACTERISTICS OF REINFORCED PLASTIC LAMINATES SUBJECTED TO AXIAL LOADING,
Abstract
This report presents a brief summary of fatigue investigations to evaluate the basic fatigue characteristics of typical reinforced plastics laminates. The majority of the evaluations were made to assay material variables such as resins and reinforcements; however, some evaluations were made to determine effects of environments, surface conditions, and loading variables. Fatigue data between 1/4 cycle and 10-million cycles show a wide spread in strength values at the 1/4 cycle, but the spread narrows considerable at 10-million cycles. Values of fatigue strength at 10-million cycles vary from 4,000 pounds per square inch for laminates reinforced with glass mat to 40,000 pounds per square inch for laminates reinforced with unwoven glass fibers.
