Abstract: With the development of transportation,public attentions have increasingly been paid to the health and safety of road and bridges.In order to realize online intelligent monitoring on the health state of traffic facilities and in the light of the existing problems of current sensing materials,a stable and highly sensitive CB/PDMS composite sensing material is developed with silicone rubber as substrate and carbon black as conductive fillings.The sample's internal structure and sensing properties are investigated.The results show that the as-prepared CB/PDMS composite flexible sensing material exhibits the stress-strain properties that typical elastomer owns,displays a quick response to pressure sensitive signals and can lead to high monitoring preciseness and accuracy to the signals with different frequencies and different compressive stress.The prepared material also shows excellent long-term stability and good stress-electrical relationship property.
