The invention relates to an FRP (Fiber Reinforced Polymer)-steel advanced composite material for structure reinforcement and a preparation method thereof. The composite material comprises a steel plate (1) and FRPs adhered on the upper and lower surfaces (2) of the steel plate (1). The preparation method of the composite material comprises the steps of: polishing and rinsing the upper and lower surfaces (2) of the steel plate (1); painting adhesive on the treated surfaces; adhering the FRPs; and compacting and exhausting until the adhesive are solidified. The FRP-steel advanced composite material has the advantages of combining the nonlinearity of the steel plate and the high strength of the FRP and ensuring that the reinforced materials have better damage control ability. The advanced composite material has the advantages of being high in strength, high in elasticity modulus, good in ductility, light in weight and low in cost, and can be widely applied to engineering structure reinforcement.
Description
Technical field
The present invention relates to building and civil engineering structures reinforcement technique field, particularly a kind of FRP-steel advanced composite material (ACM) that is used for structural strengthening and preparation method thereof.
Background technology
Along with China's rapid development of economy, a lot of existing buildings need be reinforced it because the factors such as increase of endurance issues, actual working load cause the bearing capacity of structural elements not enough.Based on to the modernization restructuring of existing building and reinforce critical role in engineering circle of today; The scientific research personnel has begun the exploration to new reinforcing mode in the sixties of eighties of last century; Develop the novel material that is applicable to reinforcement technique according to the development of material science; And constantly improve existing reinforcing mode, explore the reinforcement technique that makes new advances simultaneously.
In reinforcing mode commonly used at present, the application of steel plate and FRP is the most extensive.Nineteen sixty; The Bresson of the L ' Hermite of Switzerland and Germany has started the reinforcement technique of outside steel bonding, and steel plate is applied in the reinforcing engineering functional, does not influence structure outward appearance and usage space; The strengthening construction cycle is short; Material consumption is little and technology is easy, and still, there are some shortcomings inevitably in the affixing steel plate reinforcement method in the engineering practical application.The first, the steel plate in the engineering practical application is mild steel mostly, all has the corrosion characteristic, so it when being used for the reinforcing of bridge structure, has influenced the effectiveness of steel plate reinforcement because of muriatic erosion in the traffic waste gas causes the corrosion of steel plate and colloidal interface; The second, the adhesive durability between steel plate and the concrete can't be able to confirm to guarantee; The 3rd, when reinforcement by sticking of sheets was used to design, in the under-reinforced beam scope, the reinforcing of steel plate receives pasted thickness (common 2～6mm) and paste the restriction of the number of plies (not more than two layers).
Carbon cloth obtains increasingly extensive employing as a kind of novel composite material in the practical application of in recent ten years reinforcing engineering, the scientific research of corresponding relevant carbon fiber reinforcement method is also progressively deeply.The carbon fiber plate of the PAN base that adopts during structural strengthening is repaired, its intensity is tens times of structural steel, plays mould and structural steel in same level and increase.It is used for the reinforcing and repairing xoncrete structure, and strength-weight ratio is high, and consolidation effect is remarkable, and is heat-resisting and corrosion resistance is strong, and excellent in durability is applied widely.But owing to often show as anisotropy, the intensity and the elastic modelling quantity of machine direction are higher; And the intensity of vertical fibers direction and elastic modelling quantity are lower; The tensile strength of machine direction is high nearlyer 30% than compression strength, and its anisotropic characteristics make structure on stressed, the phenomenon that is different from traditional structural materials arranged, like the stretching warping phenomenon; So when carrying out the fibre structure design, need both direction is designed; The shear strength of fibrous material, interlaminar shear strength are merely 5%～20% of tensile strength, and the shear strength of metal is about 50% of its hot strength, and this makes the problem that is connected to become of fibrous structures.In addition, compare with steel, fibrous material intensity has bigger discreteness, and compares with concrete, and the fire protecting performance of fibrous material is relatively poor.
Summary of the invention
The objective of the invention is to combine the advantage of steel plate and FRP, overcome both shortcoming and defect, propose a kind of advanced composite material (ACM) that is used for structural strengthening.
Technical scheme of the present invention is:
One, a kind of FRP-steel advanced composite material (ACM) that is used for structural strengthening comprises steel plate (1), it is characterized in that: be pasted with fiber-reinforced polymer FRP on the upper and lower surface (2) of said steel plate (1).
As preferred version:
The thickness of described steel plate is 2 ~ 6mm.
Described fiber-reinforced polymer FRP is a kind of among carbon fiber reinforced polymer CFRP, glass fiber reinforced polymer GFRP, the basalt fiber-reinforced polymer BFRP.
Two, a kind of preparation method who is used for the FRP-steel advanced composite material (ACM) of structural strengthening is characterized in that: may further comprise the steps:
1) processing is polished, scrubbed to surface of steel plate;
2) on the surface of steel plate of handling well, smear binding agent;
3) through the binding agent of smearing on the surface of steel plate fiber-reinforced polymer FRP is sticked on the surface of steel plate of handling well, and compacting, exhaust, solidify.
As preferred version:
The thickness of described steel plate is 2 ~ 6mm.
Described fiber-reinforced polymer FRP is a kind of among carbon fiber reinforced polymer CFRP, glass fiber reinforced polymer GFRP, the basalt fiber-reinforced polymer BFRP.
Compare the technique effect below the present invention has obtained with existing reinforcement material:
1, the present invention is used for structural strengthening, and before stressed steel plate surrender in early stage, mainly stressed by steel plate, after the steel plate surrender, the high-strength performance of FRP is able to performance, and the rigidity of strenthening member improves.
2, the present invention can effectively solve the fragility problem of FRP material, remedies the deficiency of single FRP reinforcement technique, simultaneously, can reduce the thickness of reinforcement material, significantly improves the stress performance that is reinforced member, breaks through the limitation of single steel reinforcement technique.The high epistasis of the non-linear and FRP of steel is combined, improve the material ductility in the use, and reduce cost.
3, the advanced composite material (ACM) of the present invention's preparation has the intensity height, plays the advantage that mould is high, ductility is good, in light weight, price is low, can be widely used in the engineering structure reinforcing.
