Flexural fatigue of short fiber reinforced high temperature thermoplastics
Short fiber reinforced thermoplastics are gaining increasing importance in the development of composite technology. In this investigation, the studies focus on three types of short glass fiber reinforced thermoplastics: (1) polyetherimide (PEI), (2) polyethersulphone (PES), and (3) polyetheretherketone (PEEK). These matrices possess good resistance to aviation fluids and ability to withstand high temperatures up to 600/sup 0/F. Specimens were evaluated at room temperature and at elevated temperatures under both static and dynamic loads. Fatigue tests reported herein were performed on Krouse sheet bending fatigue machines, operating at 1750 cpm and a constant deflection mode. Fatigue data are presented in traditional S-N plots. 3 references, 5 figures.
