Abstract

The invention discloses a method of industrially preparing a steel-continuous-fiber composite bar. The method comprises the following steps: sequentially compounding rough fiber yarns and fiber yarn bundles dipped with resin on the surface of a reinforcing steel bar to form the fiber compound bar. The fiber compound bar compounded by the process has a reasonable structure and the fiber yarn bundles used as an enhancing material are fully dipped with resin, so that the inner and outer interfaces have good adhesive performance to effectively satisfy the design strength of the reinforced concrete structure. Meanwhile, the bar further can overcome the deficiencies of high brittleness and high price of existing fiber reinforced plastic (FRP) and is good in actual using effect.

Description

technical field [0001] The invention relates to a method for industrially preparing steel-continuous fiber composite bars, in particular to a manufacturing process for composite bar reinforcing materials used in reinforced concrete structures, and belongs to the field of composite materials. Background technique [0002] Reinforced concrete structure (RC structure) is a structure built with steel bars and concrete. The steel bars bear tension and the concrete bears pressure. It has the advantages of firmness, durability, good fire resistance, saving steel and lower cost than steel structures. One of the more common construction forms in the construction industry, it is mostly used in various super high buildings and long-span structures, such as bridges, tunnels and other load structures. In its structure, as the basic reinforcing material, steel bar has strong comprehensive performance, but it has disadvantages such as easy corrosion. Based on this situation, in recent year...
