Description

Fishing rod

Technical field

The present invention relates to fishing rod, be specifically related to have fishing rod by the pole pipe of fiber-reinforced resin system.

Background technology

Because the light and slow ground of bamboo pole is crooked, resilience (reinstatements) is also releived, and is acknowledged as feeling good of fishing always, so the bamboo pole fishing rod of many types of having pass by produce and market.

But, bamboo pole is that natural bamboo process is added hot-working, goes to save processing back uses such as processing, kinking japanning processing, its performance is subjected to the growing state of bamboo and the influence of processing method to a great extent, the quality of the flexibility of each pole etc. is uneven, for this reason, there is the problem that is difficult to produce the uniform product of quality in bamboo pole.

So in recent years, as the substitute of bamboo pole, use the fishing rod of making as the fiber-reinforced resin of reinforcing fiber by carbon fiber or glass fibre to become main flow.

The fishing rod that forms with fiber-reinforced resin like this, owing to be not the natural products that directly uses as the bamboo pole,, compare with bamboo pole simultaneously so product quality is more even, owing to have advantage in light weight, that intensity is high, be almost in recent years all fish use.

But, the fishing rod that the fiber-reinforced resin that carbon fiber or glass fibre are used as reinforcing fiber is made, can external force bendings such as hook have been gone up because of pulling or the fish of fish, in case but this external force reduces or disappears just to restore to the original state at once easily, so the recovery to bending is too responsive, consequently exist reaction to lack the problem of the sensation of fishing than machinery.

Summary of the invention

The present invention be directed to above-mentioned the problems of the prior art, can producing the uniform product of quality, and provide and as bamboo pole, the recovery of bending is relatively releived and rich fishing rod of fishing sensation is that problem is finished.

The inventor inquires into keen determination at above-mentioned problem, found that as in the fishing rod of making by the fiber-reinforced resin that uses reinforcing fiber, the fiber of the appointment thickness that use is extracted out from bamboo is as the situation of reinforcing fiber, than the situation of having used glass fibre or carbon fiber with the same manner, recovery action to bending is releived, thereby has finished the present invention.

That is for solving above-mentioned problem, fishing rod of the present invention is the fishing rod with pole pipe of being made by fiber-reinforced resin,

It is characterized in that: at the innermost layer of above-mentioned pole pipe, carbon fiber along the circumferential direction is provided with as reinforcing fiber, in the intermediate layer, carbon fiber is provided with vertically as reinforcing fiber, and, the fine bamboo fibre of opening of diameter 0.01～0.5mm is provided with vertically, and the resin pickup of this bamboo fibre accounts for 20～50% of weight, and outermost carbon fiber along the circumferential direction is provided with.

Diameter 0.01～0.5mm opens fine bamboo fibre, usually spring rate within the specific limits, this fiber by using specified amount is compared with the fishing rod (bamboo pole) that uses bamboo as reinforcing fiber, can make the quality discrepancies such as flexibility of each pole less.

And, though its effect is indeterminate, but be to use above-mentioned bamboo fibre as reinforcing fiber, can make above-mentioned fishing rod after because of the external force bending in case reduce or when removing this external force, the plasticity that is for the moment a little than the occasion of using carbon fiber, needs the long time to restore to the original state, richer sensation of fishing is releived in recovery action to bending.

In addition, in the present invention, the diameter of bamboo fibre be meant with the perpendicular cross section of direction of principal axis in farthest the distance (being maximum diameter) of point-to-point transmission, this numerical value is measured with the microscope cross-section photograph.

Among the present invention, above-mentioned bamboo fibre points to the direction of principal axis of pole pipe.Like this structure function has the effect of releiving to the recovery action of bending, takes place because crooked to produce the possibility that perfect plasticity is out of shape also less.

In addition, above-mentioned bamboo fibre preferably implements to add hot-working.

The bamboo fibre of having implemented to add after the hot-working is used as reinforcing fiber, can make it become high resiliency and be not easy to produce the product of perfect plasticity distortion.

At this, adding hot-working is exactly with bamboo state before fiber is drawn out of or the fiber condition that has been drawn out of, heats and makes the processing of its moisture and oil content evaporation in the mode that does not make its carbonization.

This adds hot-working, usually heating several seconds (being about 1～10 second specifically) and finishing in 150～800 ℃.

This adds hot-working also can use firing furnace, for example when making the pole pipe (as the carbon pole) make as the fiber-reinforced resin of reinforcing fiber with carbon fiber, is used for heating so that use during hardening of resin.

Also have, in the present invention,, it is desirable to further have carbon fiber or glass fibre as above-mentioned reinforcing fiber.

Only use bamboo fibre, under the very big situation of power effect outside, have big bending takes place, the possibility of the plastic deformation that permanent not resilient is such, but, reduced the possibility that this type of plastic deformation takes place owing to further have carbon fiber or glass fibre as reinforcing fiber.

This carbon fiber or glass fibre preferably point to circumferencial direction.

According to structure like this, even because very big bending etc., pole pipe section is deformed into ellipse from circle, also owing to have the carbon fiber or the glass fibre that point to circumferencial direction to play booster action, not frangibility, burst apart.
