  1. Composites in Fishing Rods Marc Crans Chris Henderson Matthew Leroux DerylSedran

  2. History of Fishing Rods • Traditional materials included bamboo and other types of wood • Bamboo still used because of good dampening properties • Steel rods introduced in early 1900s • Fiberglass rods introduced in 1940s • Carbon fiber rods introduced in 1970s

  3. Modern Fishing Rod Materials • Woven fiberglass composites • Carbon fiber composites (often mislabeled as graphite) • Boron and various ceramics sometimes used for fibers • Split bamboo rods still fairly common

  4. Ideal Fishing Rod Properties • Flexibility • Light weight • Fatigue resistance • Withstand Environmental Conditions

  5. Fishing Rod Specifications • Classified in 3 ways: • Power – Strength of rod, how far it will bend • Light, ML, Medium, MH, Heavy • Action – How the rod flexes and how quickly the tip returns to neutral • slow, medium, fast, extra fast • Modulus – Rod materials (usually fibers) • low, medium, high

  6. Fishing Rod Specifications Action Power

  7. Fishing Rod Specifications Optimum rod depends on fishing technique: • Trolling/ Downrigging: Fiberglass, heavy, med action • Crankbaits/Spinners: Carbon fiber, med action • Soft Plastics: High modulus, fast or extra fast action

  8. Fishing Rod Design • Geometries • Tapering • Action Geometries • Wall Thickness • Length • Composite Materials • Carbon Fiber / Epoxy Resin • Fiber Glass

  9. Manufacturing • A pre-impregnated synthetic fibre sheet is hand cut into a particular shape which varies by rod type • The specific weave and weight of the sheets are specially designed for each manufacturer • The cut-out is wrapped around a tapered steel mandrel and hot rolled

  10. Manufacturing

  11. Manufacturing • Majority of the fibres are lined up along the length of the mandrel (80-90%) • A thin polymer film is wrapped around the mandrel before heat treating it to cure the resin • The polymer film shrinks increasing pressure on the blank as the resin hardens • Blank is removed from the film and mandrel, sanded then coated in protective materials.
