Description
Technical field
The present invention relates to a kind of continuous fiber-steel wire composite board, belong to the new material exploitation in fields such as building, traffic, water conservancy.
Background technology
At present, fiber the most frequently used in the engineering structures mainly contains: carbon fiber (Carbon Fiber), glass fiber (GlassFiber), aramid fiber (Aramid Fiber), and various fibers respectively have pluses and minuses:
Carbon fiber: intensity height, modulus of elasticity height, light weight, but its limiting strain is little, and the precursor technology is subjected to external monopolization and control substantially, and application cost is too high in civil engineering structure.
Glass fiber: advantage is that price is low, domesticizes, and hot strength is higher; Shortcoming is that the bullet mould is low, and durability is not ideal, and environment is unfriendly.
Aramid fiber: advantage is that intensity and bullet mould are all higher, particularly has better heat-resisting and fabulous toughness and shock resistance.Shortcoming is that compressive strength and modulus of compressibility are lower, is organic fiber, and humidity and ultraviolet light resistant are poor, and the surface is poor with the composite adhered property of matrix.Price height, precursor technology also are subjected to external monopolization and control substantially.
Fibre reinforced composites (fiber reinforced polymer is called for short FRP) are the high-performance new materials by fibrous material and matrix material mix by a certain percentage and the certain technology of process is compounded to form.This material came out in the forties in 20th century, originally was used for high-tech areas such as Aeronautics and Astronautics, national defence, was widely used in fields such as automobile, chemical industry, medical science gradually afterwards.In recent years,, lightweight high-strength, advantage such as corrosion-resistant with it, beginning is used widely in civil engineering structure, and is subjected to the extensive concern of engineering circle.
Since the particularity of civil engineering, the general character shortcoming that the application of FRP in this field exists, comprising: 1. ductility is poor, and existing FRP limit of stretch strain generally is not more than 3%, so can't satisfy the requirement that the structure that is strengthened has desirable ductility and high anti-seismic performance; 2. the price height can't satisfy the requirement of civil engineering structure material low cost, has hindered it and has applied on a large scale; 3. shear resistance is poor, and the FRP muscle is a kind of crystalline material, and vertically with the ratio of transverse strength big (being about 20: 1), the fragility easy fracture of FRP can't adapt to the requirement of civil engineering special construction technology (as concrete vibrating, anchoring, bending etc.); 4. it is low to play mould, even the bullet mould of CFRP muscle also has only about 150GPa, can't guarantee that the structure after its enhancing has good rigidity, has directly influenced the normal operational phase performance of structure; 5. performance is discrete, and FRP biceps performance is more discrete than metal material; 6. the part fiber durability is undesirable, can be poor as the glass fiber alkali resistance; 7. fire resistance is undesirable; 8. use in structure, intensity often can not be fully played, and waste is big.
Want essence to solve above bottleneck problem, promote FRP and associated materials more extensively and the application of science in field of civil engineering, must develop more new material, especially should be noted that 2 points: common some shortcomings that exist of (1) fiber, determined to mix modification and can not deal with problems well merely between sometimes multiple fiber, must carry out compound with the diverse material of performance; (2) new material of in civil engineering, particularly in newly-built structure, using except satisfying high performance requirement, also must cost low and application property ideal etc.
Summary of the invention
