Paper Abstract

Optical fibre Bragg grating strain sensors are used to monitor the dynamic loads experienced by a tufting needle installed on a commercial robot-controlled tufting tool during the tufting of a dry carbon fibre preform. The influence of the thread and thickness of the preform lay-up were investigated. Maximum axial compression strains of ~-250 με, and bending strains of 1100 με were measured during the tufting of a 4 ply quasi-isotropic carbon fibre dry preform.
