  • Patent number: 10085433
    Abstract: A tip rod made of a fiber reinforced resin has a solid structure at least at its distal end portion. The tip rod is formed by dispersing reinforcement fibers in a matrix resin, molding the matrix resin that contains the reinforcement fibers into a prescribed shape, and heating the molded matrix resin that contains the reinforcement fibers to be cured. An average diameter of the reinforcement fibers is 3 to 15 ?m, an average length of the reinforcement fibers is 0.5 to 10 mm, a content of the fibers dispersed in the matrix resin is 3 to 50 wt %. The solid structure of the tip rod includes an outer layer, an intermediate layer, and an inner layer in which the reinforcement fibers are directed in a different direction for each layer. Alternatively the structure may include the outer layer and the inner layer.

  • Patent number: 5076004
    Abstract: The present invention relates to a fishing rod having a rod tube formed from synthetic resin-impregnated high strength fiber and to a production method thereof. The rod tube of the present fishing rod is filled with resin containing microglobules in a dispersed state. This makes a lighter and stronger fishing rod which withstands extreme deflection. The production method according to the present invention can adjust the ratio of the filled resin and the dispersed microglobules at the tip and butt portions of the rod. Accordingly, the weight, strength, and condition for each portion of the rod can be controlled as required.
