Carbon nanotubes have a widely potential application in health monitoring of polymer composites due to the excellent electro- mechanical properties. Research advances in carbon nanotubes sensing in polymer composites are reviewed： carbon nanotuhes filler, carbon nanotubes coated fiber, carbon nanotubes yarn and carbon nanotubes paper. This paper also focuses on the analysis of the com- mon core principle of carbon nanotubes sensing, namely using carbon nanotubes sensing network to monitor structural strain injury. Car- bon nanotubes paper can resolve problems such as the hard dispersion in the blending of carbon nanotubes and resin, the collaborative deformation of carbon nanotubes coated fiber and the whole structure monitoring of carbon nanotuhes yarn. Carbon nanotubes paper pro- vides the engineering application condition for carbon nanotubes sensing. The engineering application of carbon nanotubes sensing in health monitoring of polymer composites is the future research direction.
