Abstract
The fatigue lives (i.e., the number of cycles to failure) of short fiber reinforced thermoplastic matrix composites were investigated. First, S-N curves were generated at stress ratios of R = 0 and R = -1 for short glass fiber reinforced Copolyamide coupons with 0° (30% or 50% fiber content by weight), 45° (50% fiber content) and 90° (30% or 50% fiber content) fiber orientations. Second, these S-N curves were compared to data reported in the literature for a wide range of short glass and short carbon fiber reinforced thermoplastics materials. On the basis of these comparisons, all available data were “collapsed” on two S-N curves, one for R = 0 and one for R = -1.
