Abstract

Fiber Bragg Grating (FBG) sensors are fast becoming a key instrument for the development of the aerospace sector due to their exceptional physical-mechanical characteristics. In order to introduce these innovations on airplanes it is necessary to investigate the effect of their assembly process. Few studies have investigated the bonding strategy in any systematic way and no detailed investigation was addressed to the aerospace use. In the present work a new tool is presented; it allows to control the deposition of the resin on tensile specimens in width and thickness. This resin will bond FBG sensor with the specimen and the outcome will be compared with a traditional strain gauge placed in the opposite face. The specific objective of this study is to prepare the standards to define subsequently the best strategy to minimize the disturbance caused.
