Industrial preparation method of steel-continuous-fiber composite bar with rib texture

Abstract

The invention discloses an industrial preparation method of a steel-continuous-fiber composite bar with a rib texture. 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; and arranging a surface rib texture which can improve the adhesive performance on the outer surface of the fiber compound bar which is formed by compounding. The bar 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 an industrial preparation method of a ribbed steel-continuous fiber composite bar, in particular to a manufacturing process of a composite bar reinforcing material used in a reinforced concrete structure, 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...
