Electrical-Mechanical Behaviors of 3D Carbon Fiber/Epoxy Angle Interlocking Woven Composites Under Three-Point Bending
Resistance response of the three-dimensional(3-D)angle interlocking woven composite under three-point bending load can provide a theoretical basis for structural health monitoring(SHM).Here we investigated the electrical conductivity,mechanical properties and electrical-mechanical of the angle interlocking woven composite.The directional effect of angle in-terlocking woven composites depends on the number and length of yarns in the corresponding direction.The changes of load and resistance change could be divided into three stages during bending.In the first stage,the load of 1the sample reaches the maximum value,and the sample goes through the elastic stage and yields near the maximum load.In the second stage,the load of the sample decreases gradually or a yield plateau appears after the decrease.In the final stage,the load of the sample decreases rapidly,and the sample is completely destroyed.The resistance change of the samples goes through three stages:have no change,increase slowly,and increase sharply.By observing the fracture section of the sample,the resist-ance change can be correlated with the failure process.
