TRANSCRIPT
History of Fishing RodsTraditional 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 1970s2
3
Modern Fishing Rod MaterialsWoven fiberglass composites
Carbon fiber composites (often mislabeled as graphite)
Boron and various ceramics sometimes used for fibers
Split bamboo rods still fairly common
Ideal Fishing Rod PropertiesFlexibility
Light weight
Fatigue resistance
Withstand Environmental Conditions

Fishing Rod SpecificationsClassified 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
5
Fishing Rod SpecificationsOptimum rod depends on fishing technique:Trolling/ Downrigging: Fiberglass, heavy, med
action Crankbaits/Spinners: Carbon fiber, med actionSoft Plastics: High modulus, fast or extra fast action

ManufacturingA 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
9
ManufacturingMajority 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.
