Original abstract
The main scope of this article is to present the results of several experiments that were performed on the developed home-made composite recurve bow fabricated from ash wood, GFRP and CFRP. The results are compared with validated FEM. The FEM is validated by comparison with: measured draw force, measured strain during the bow draw at two selected locations, measured signals at the same locations of the excited bow without the string from which eigen frequencies are evaluated using FFT. All measured data show good compliance with the validated FEM. The main advantage of those experiments is a possible alternative evaluation of stiffness orthotropic material properties without the need of dedicated test setup generally connected with extra cost.
