Investigation Of Metal Stiffeners In Frp Composite Gears For Increasing Tooth Bending Strength
Abstract - In the case of Plastic (FRP)-Metal hybrid composite technology, the properties of two materials are combined in
an optimal manner, resulting in synergistic effects that cannot be achieved with the respective materials alone. This hybrid
composite technology has a great potential in geared transmissions where plastic-metal gears can lead to low cost, light
weight, high strength & improved performance of the system. The work is intended towards enhancing the tooth bending
strength of fiber reinforced plastic gears by intrusion of metal stiffeners inside the geometry of each tooth.
FEA is carried out for investigation of the effect of various cross sections used for stiffener geometry and different materials
used for remaining part of gear. Ls-Dyna and HYPERMESH software are used for FEA study. To ensure the correctness of
the results obtained by FEA, these results are correlate with available material test data.
