Abstract: The rod has replaceable line guides and consists in at least one tubular element incorporating a socket insert serving to accommodate a corresponding shank with which the guide is provided, the insert being located between the internal and external surfaces of the tubular element, and its socket filled with a quick-setting melt-down glue that ensures stable anchorage of the shank; the tubular structure is fashioned by winding first sheets of composite material onto a mandrel until a given thickness is reached, then applying and fixing the insert to the external surface of the first winding to establish the socket, whereupon further material is wound on to an increased thickness, sufficient at least to embed the insert. Alternately, the insert may be made from dissolvable material.

Abstract: The multi-layer structure enables the accomplishment of very light-in-weight and squashing-resistant tubular elements, in particular fishing rods, as it consists of a plurality of layers made of very thin carbon fibers (1) having a high or very high modulus of elasticity, disposed parallel to and alongside each other and impregnated with a matrix resin, said layers being alternated by further layers of very thin aramide fibers (2) disposed parallel to and alongside each other and impregnated with a matrix resin. Carbon fibers and aramide fibers are inclined with respect to each other.
