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.
Claims5
A fishing rod multi-layer composite, the fishing rod being generally cylindrical and having a longitudinal axis, said composite comprising:
- an outer layer of graphite fibers, said graphite fibers being oriented parallel to the longitudinal axis of the fishing rod;
- a first alternate layer of aramide fibers, disposed inwardly adjacent to said first outer layer, said aramide fibers being orientated nearly perpendicularly to said graphite fibers;
- a first inner layer of graphite fibers oriented parallel to the longitudinal axis of the fishing rod disposed inwardly adjacent to said first alternate layer;
- and
- a matrix resin impregnating all layers so that an integral composite is formed from said layers and said matrix.
