摘要：
In order to realize in-situ structural health monitoring of 3-D braided composites, 3-D five-directional braided composite preforms embedded with carbon nanoyarns were prepared, a carbon nanoyarn strain sensing experimental system based on 3-D braided composite specimens were established, and the strain sensing characteristics of carbon nanoyarns embedded in 3-D braided composites were analyzed. The results show that during the process of monotonic stretching and cyclic loading and unloading, the resistance change ratio of carbon nanoyarn sensors embedded in 3-D braided composites and the strain of specimens maintain a good linear correlation. After cyclic loading and unloading under heavy load, the residual resistance generated by the carbon nanoyarn sensors can be used to detect the damage or cumulative damage of specimens. The strain sensing equation for the net difference of resistance change and the net difference of mechanical strain established after introducing the coefficient of correlation of resistance to strain could achieve in-situ structural health monitoring of 3-D braided composites.
