　　The mechanical and strain sensing properties of carbon nanotube composite yarns(CNTs/PDMS)with different weight percent of PDMS were studied.The CNT/PDMS composite yam was prepared by infiltration method.Pictures of diameter of CNT composite yarns were obtained though polarized light microscope.Resistance change values of CNT composites under stretching were obtained though the single fiber strength tester,digital multimeter,related mechanical and electrical software.The changes of mechanical properties,electrical properties and sensing performance of pure and composite CNT yarns were discussed and analyzed.The results showed that the strength of CNT yarn declined after it was composited with PDMS polymer.In addition,the conductivity and sensing performance of CNT yarns improved significantly.The most suitable CNT composite yarn occurs at PDMS mass fraction of 1%when strength and sensing properties were all considered.
