The presented study focuses on structural health monitoring technique with the goal to predict induced damage and assess the residual strength of impacted structure. Herein, the primary problem of impact force reconstruction is investigated on an airfoil segment (part of a propeller blade for a large fan) made of laminated composite with attached piezoelectric transducers. The segment is made from carbon textile using RTM technology. The reconstruction is based on deconvolution method and transfer functions. The efficiency of the proposed approach is tested for all impact locations used to calibrate the system, and also on several additional locations. The interpolation of transfer functions is used to increase the accuracy of the reconstruction.
