Abstract:

In sporting goods manufacturing, such as in fishing rod design, new products are created using an Edisonian process. By changing the layup and geometry of the carbon fiber prepreg layup, a rod can be constructed that lend itself to a specific application. This thesis will present an integrated computational materials engineering (ICME) approach for carbon fiber fishing rods using simulation theory and experiments. The computations are based on the finite element method (FEM), including the use of integrated Euler-Bernoulli beam theory in MATLAB.  The experimental methodology uses three-point bending (3PB) flexure test analysis to determine values for Young’s Modulus which are then incorporated into numerical solutions and modelling.  Discretized values for Young’s Modulus are used in thin-walled tapered cylindrical Euler-Bernoulli beam models through integrated second area moment of inertia and non-integrated approaches.  The 3PB flexural experiments performed on a test rod section demonstrate correlation to FEM solutions, along with convergence between non-integrated and integrated beam models.  A modal analysis on the beam provides insight to the free-vibrational effects of a fishing rod under differing user-induced boundary conditions.  Through this ICME approach, rod manufactures can understand properties in rod prototypes and better develop future rod models.
