Abstract
Abstract A fishing rod is provided which has a hollow rod body. The rod body is made from laminations of a plurality of plies of fiber-reinforced resin wherein the majority of the fibers are aligned with the axis of the rod and wherein each ply of fiber-reinforced resin contains randomly aligned chopped fibers interconnecting the parallel fibers to distribute the load and maximize the crush and hoop strength of the rod segment.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
115 words
A fishing rod having a hollow tapered body of generally circular exterior cross-section, the rod having a hollow interior extending along the rod axis, said rod body being constructed of laminations of a plurality of plies of fiber reinforced resin in each of which is a sheet of collimated parallel generally axially aligned reinforcing fibers treated with a mixture of resin and short chopped reinforcing fibers which are uniformly dispersed throughout the resin and randomly oriented, the viscosity of the resin having been selected for supporting the dispersed short chopped reinforcing fibers and the length of the short chopped reinforcing fibers having been selected for forming bonds between adjacent collimated parallel generally axially aligned fibers.
Claim 2
Dependent Claim
115 words
A fishing rod having a hollow tapered body of generally circular exterior cross-section, the rod having a hollow interior extending along the rod axis, said rod body being constructed of laminations of a plurality of plies of fiber reinforced resin in each of which is a sheet of collimated parallel generally axially aligned reinforcing fibers treated with a mixture of resin and short chopped reinforcing fibers which are uniformly dispersed throughout the resin and randomly oriented, the viscosity of the resin having been selected for supporting the dispersed short chopped reinforcing fibers and the length of the short chopped reinforcing fibers having been selected for forming bonds between adjacent collimated parallel generally axially aligned fibers.
Claim 3
Dependent Claim
16 words
The invention of claim 1 wherein the collimated and the short reinforcing fibers are graphite fibers.
Claim 4
Dependent Claim
42 words
The invention of claim 2 wherein the short graphite fibers have a nominal length from 0.010 to 0.030 inches and diameters of from 0.0002 to 0.0007 inches and wherein parallel oriented roving strands form the collimated parallel generally axially aligned reinforcing fibers.
