For CFRTP of short carbon fibers in a resin matrix of polyacetal, the effects of carbon fiber content, temperature and notch radius on fatigue behavior have been investigated. Fatigue strength increases with increasing carbon fiber content and decreases with increasing test temperature. Logarithm of fatigue strength for CFRTP with 30% fiber content is proportional to the reciprocal of temperature, 1/T. However, the fatigue strength of CFRTP depends little on the notch radius.
