    • Abstract
  • The bending fatigue properties of 3238A/EW250F composite material were studied by three points bending loading mode.The results show that the dispersion of bending fatigue life of the composite was rather small,and the fatigue life of all test samples could meet 90% confidence median life requirements.All samples were destroyed at the effective part,and after surface delamination there was still a long period of life.The fatigue limit expressed with dynamic stress of 3238A/EW250F composite laid in 0°direction was 73.2 MPa.
