A novel smart bolt combined with fiber EFPI/FBG micro-structures is presented to monitor the state of tightening force of a bolted aerospace structure under high temperature circumstance. In this smart fiber bolt, the fiber EFPI micro-structure is applied to obtain the length variation in the direct of bolt axis under the effect of tightening force. And the fiber Bragg grating micro-structure is applied to obtain the bolt temperature. With the parameters obtained by the fiber EFPI/FBG micro-structures, the tightening force can be obtained through the approach presented. Test samples which are 50mm long M8 bolts combined with fiber EFPI/FBG micro-structures are made and tested by a universal testing machine with a heating chamber. The test results show that the smart fiber bolt presented can be used to obtain maximum 10kN tightening force under the temperature of 500 degree centigrade with maximum relative error 3.1%. This smart fiber bolt can be used to monitor the state of structure connection under high temperature circumstance.
