Detection device and method for detecting mechanical properties of bonding surface

The invention discloses a detection device and method for detecting mechanical properties of a bonding surface, and belongs to the field of mechanical property detection. The detection device is characterized by comprising a detection test piece and a to-be-detected body provided with at least one bonding surface, wherein an optical fiber sensor is arranged on the bonding surface; the detection test piece comprises a stretching piece and a bonding plate; a lower end face of a lower end of the stretching piece is horizontally arranged or arranged to be an inclined face; an included angle between the inclined face and the horizontal plane is an acute angle; and the bonding plate is fixedly connected with the lower end face of the stretching piece. Through structural improvement of the detection test piece and the optical fiber sensor, the detection device can be used for measuring the bonding strength of bonding surfaces with various inclination angles, meanwhile, current is not introduced in the detection proc
