Abstract:

In order to achieve comprehensive monitoring of internal damage of aerospace structural specimens, a new real-time monitoring method was proposed based on the new discovery of the twisting energy feature of carbon nanotube yarns. This method uses three-dimensional six-directional braiding technology to embed carbon nanotube yarns into aerospace composite structural specimens to construct the new type of intelligent three-dimensional composite material. Studies have proved that when internal damage occurs in specimens, the twist of the carbon nanotube yarns embedded inside the specimens will change and generate twisting energy. The principal component analysis and damage index theory were used to analyze the twisting energy data of carbon nanotube yarns. The experimental results show that the resin fractures, holes and tiny cracks in the three-dimensional braiding composite specimens will cause changes in twist electric energy. The twist electric energy of carbon nanotube yarns has a high recognition accuracy of the internal damage of the specimens, which reaches 0.002 mm in this research. This finding has of practical significance for the advancement of intelligent monitoring of aerospace structures.

Key words: carbon nanotube yarn, twist electric energy, three-dimensional six-directional braiding, damage index, damage monitoring of composite material
