Problems solved by technology
[0003] FRP bars are composite materials made of high-strength glass fibers, synthetic resins as matrix materials, and an appropriate amount of auxiliary agents. However, the materials used in FRP bars cannot be recycled, and some harmful gases are produced during the production process. Not only does it cause damage to the environment, but it even causes harm to the human body, so it hinders the promotion and application of resin tendons to a certain extent.

Abstract
The invention provides a continuous-fiber-reinforced thermoplastic composite resin rib which is prepared from a continuous-fiber-reinforced thermoplastic composite material, wherein the continuous-fiber-reinforced thermoplastic composite material is coated, split and manufactured into wires and then is pulled, extruded and secondarily manufactured into the continuous-fiber-reinforced thermoplastic composite resin rib. By means of the technical scheme, the continuous-fiber-reinforced thermoplastic composite resin rib disclosed by the invention has the beneficial effects of having strong designability, reasonably choosing resin and fiber according to an actual requirement and achieving the optimal economic effect. The continuous-fiber-reinforced thermoplastic composite resin rib has the advantages of light weight, high specific strength and specific modulus, good corrosion resistance, water resistance and abrasion resistance, sluggishness to varieties of acid and alkali, shock resistance, high breaking strain value and good design flexibility. In addition, appropriate fiber types, fiber contents and fiber orientation can be chosen to meet requirements of concrete purposes.
Description
technical field [0001] The invention belongs to the field of new building materials, in particular to a continuous fiber-reinforced thermoplastic composite resin bar used for replacing steel bars in concrete structures. Background technique [0002] Steel bar refers to the steel used for reinforced concrete and prestressed reinforced concrete. Its cross section is circular, sometimes square with rounded corners, including smooth round steel bar, ribbed steel bar, and twisted steel bar. Light round steel bars are actually small round steel bars and discs of ordinary low carbon steel. Deformed steel bars are steel bars with ribs on the surface. Steel bars mainly bear tensile stress in concrete. Due to the action of ribs, deformed steel bars have greater adhesion to concrete. knot ability, so it can better withstand the action of external force. Steel bars are widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structur...
