Basalt fiber unidirectional cloth for reinforcing engineering structure and manufacturing method of basalt fiber unidirectional cloth

Abstract

The invention discloses basalt fiber unidirectional cloth for reinforcing an engineering structure and a manufacturing method of the basalt fiber unidirectional cloth. The unidirectional cloth comprises a unidirectional cloth body made in a plain weave mode; the unidirectional cloth body comprises warp yarns and weft yarns; the warp yarns are premade continuous basalt fibers and have better flexibility, banding performance, self-lubricating performance and spinning performance; gaps are formed between the adjacent warp yarns; and the weft yarns are hot melting filaments. A segmented film forming process is adopted, the production cost is reduced, the mechanical property and the cloth cover structural stability, smoothness and permeability are improved, wrinkling during construction can be effectively avoided, and the advantages of convenient construction, good reinforcing effect, high cost performance and the like are achieved.

Description

Technical field [0001] The present invention relates to the field of engineering structural reinforcement materials, in particular, a unidirectional fabric of basalt fiber in engineering structures and its manufacturing methods. Background technique [0002] The reinforcement scheme of carbon fiber unidirectional cloth is often used when the building structure is damaged, crack, bearing capacity or design, construction, etc. The carbon fiber single-way cloth has the characteristics of light weight, convenient construction, high strength, good reinforcement effect, suitable for reinforced concrete, axial pressure, large eccentric compression and pull-up member, reinforcement, can be effective Improve the bearing capacity, seismic performance and durability of the components. It is used in a large amount of reinforcement of the bridge, the bridge, the housing column, the wall, the beam, and the floor, and can be used in the construction and reinforcement of artificial satellites an...

Problems solved by technology

[0003] However, carbon fiber cloth also has some problems, such as high unit price, non-insulation (conductive), extremely intolerant to folding, non-radiation (ultraviolet), low elongation, high thermal conductivity but low electrical conductivity. When heated, carbon fiber will be thicker and shorter

As a result, the cost of use is high, and it is difficult to apply in building reinforcement projects with high requirements such as temperature resistance, electrical insulation, and anti-magnetic properties.
