Studies on creep behavior of three dimensional braiding composites

The creep of three dimensional braiding composites were studied by creep experiments of specimens under different braiding structure, braiding angle, fiber volume content and loads. The experiment results show that the creep resistant properties of the three dimensional four directional braiding composites are worse than five directional braiding composites. The creep resistant properties can be improved with a lower braiding angle and higher fiber volume fraction. Furthermore, the creep rate is increased with the increasing of load. In addition, it is found that the power function is the best fit equation of creep curve for 3-D braiding composites.
