1. Introduction of fiber materials

Carbon fiber has high strength, high modulus, high temperature resistance, corrosion resistance, fatigue resistance, creep resistance, electrical conductivity, heat transfer and other characteristics. It is a typical high-tech product, mainly used for preparing advanced composite materials, and is widely used in aerospace, sporting goods, and industrial fields.

With the reduction of carbon fiber cost, the use of carbon fiber as the most suitable fiber composite reinforcement material in the field of civil engineering is increasing sharply year by year.

2. Carbon fiber reinforcement

CFRP reinforcement

Carbon fiber reinforcement includes carbon fiber cloth reinforcement and carbon fiber board reinforcement. Compared with the traditional reinforced concrete cross-section or reinforced steel concrete reinforcement, carbon fiber has the advantages of space saving, simple construction, no need for on-site fixed facilities, easy construction quality assurance, basically no increase in structural size and self-weight, good corrosion resistance and durability. In addition, using this reinforcement method can greatly increase the service life of the building and reduce the cost of reinforcement. Therefore, carbon fiber is favored as a new reinforcing material.

Prestressed carbon fiber plate reinforcement

Carbon fiber plate is a kind of carbon fiber reinforced unidirectional sheet. The molding process is to impregnate carbon fiber with resin and solidify it in a mold and continuously pultrusion. Using high-quality carbon fiber raw materials and good basic resin, carbon fiber sheet has good properties such as high tensile strength, corrosion resistance, shock resistance, and impact resistance. The finished carbon fiber unidirectional plate can fully exert the strength and elastic modulus of the carbon fiber, and can avoid the resin curing stage of the carbon fiber unidirectional fabric during construction.

Comparison of carbon fiber cloth reinforcement and prestressed carbon fiber plate reinforcement

Carbon fiber cloth reinforcement is convenient in construction and low in cost, without the need for complicated equipment investment. During construction, the carbon fiber cloth is flexible and can be used for reinforcement of various base surface forms.

The prestressed carbon fiber plate anchor system, by applying prestress to the carbon fiber, avoids the phenomenon of strain lag of the carbon fiber plate, so that the strength of the carbon fiber plate is effectively exerted, and the structural bearing capacity is improved. At the same time, the flexural rigidity of the bending member is increased, the deflection of the original member is reduced, the deformation and crack expansion of the member are suppressed, and the contradiction of the ratio of carbon fiber strength and elastic modulus is too high.
