| Abstract: | An inorganic adhesive for sticking and coating of FBG sensors is prepared by adding SiO2,TiO2 or SiC into Si3N4.The agglomerative structure of the new adhesive is observed using AJ-Ⅲa atomic forced microscope,the mechanic performance of the adhesive is tested using QJ210-500N electronic multipurpose material testing machine,and the performance of FBG sensors coated with above-mentioned adhesive for measuring temperature and pressure is tested with MS9710C spectrum analyzer.The results show that the tensile strength of the adhesive is 45.01 MPa,its shearing strength is 44.34 MPa,and its maintaining rate of tensile-shearing strength after soaking is higher than 89.8%.The temperature and pressure sensors coated with above-mentioned adhesive can be used in the circumstance of 301.8 ℃ and 42 MPa,as well as under the existence of oil,steam and water. |
