Problems solved by technology

Low-modulus carbon fiber has good toughness and high firmness, but poor rigidity and heavy weight; while high-modulus carbon fiber is light in weight and strong in rigidity, but not high in firmness, brittle, and easy to break
In addition, because the carbon fiber material is conductive and expensive, the fishing rod made of carbon fiber is expensive and has no insulating function.
Due to the single laying method of the fishing rod reinforced with glass fiber, the strength and modulus of the produced fishing rod are relatively low
[0004] To prepare an ideal fishing rod, in addition to choosing a reasonable fiber for reinforcement, it is also necessary to select a suitable matrix resin and fishing rod preparation process to improve the bonding force between the resin and the fiber, thereby improving its mechanical properties. In the prior art, the bonding force between the matrix resin and the fiber is not strong, micropores and air bubbles will appear during the curing process, and its strength and toughness will decrease relatively quickly when used under long-term high-strength and high-frequency conditions. It is easy to cause the deformation of the rod body, the surface coating of the rod body falls off, and the service life is short

Description

technical field [0001] The invention relates to the technical field of fishing gear, in particular to a carbon fiber-based composite material fishing rod and a preparation method thereof. Background technique [0002] Along with the continuous improvement of people's living standards, fishing has become a kind of important entertainment and leisure activity for people, and competitive fishing is also carried out frequently like a raging fire. A class of fishing gear that is indispensable in the fishing process is a fishing rod, which plays a decisive role in the fishing process. An ideal fishing rod not only needs to have good mechanical properties such as tensile strength, yield strength and elongation, but also requires excellent antistatic performance, toughness and aging resistance. [0003] The material of existing fishing rod itself has two kinds of glass fiber and carbon fiber, and the material that mainly uses at present is carbon fiber. Carbon fiber is divided int...
