Abstract
The invention discloses a sheet steel glass fiber composite rib in radial distribution and a manufacturing method thereof. Multiple sheet steel and glass fibers are cohered by virtue of a resin substance and are compounded to form the sheet steel glass fiber composite rib in radial distribution. Sheet steel is uniformly distributed at the center of the composite rib around the annular direction of the axis of the composite rib; the part between the sheet steel and the glass fibers and between the glass fibers is filled with resin matrix. A region from the terminal ends of the sheet steel to the surface of the composite rib is a composite rib outer layer; spiral fiber bundles subjected to gum dipping are spirally wound on the surface of the composite rib to form ribs at intervals; sand particles are densely distributed on the surface of the composite rib. The preparation method comprises the steps of enabling pre-processed sheet steel and the glass fiber bundles subjected to the gum dipping to penetrate through a plurality of splitting plates together, then enabling the sheet steel and the glass fiber bundles to enter a pultrusion die for pultrusion, winding the spiral fiber bundles subjected to the gum dipping on the surface of the molded composite rib by virtue of spiral winding equipment, and then carrying out sand blasting, heating, solidifying and cutting to obtain an expected product. The sheet steel glass fiber composite rib in radial distribution has the advantages of high tensile strength, corrosion resistance, good fatigue resistance, relatively good ductility, high structure safety, matured pultrusion process adopted by the manufacturing, easy quality control and the like.
Description
Technical field
The present invention relates to civil engineering structural material is and in particular to a kind of radial arrangement steel disc glass fibre is combined
Muscle and preparation method thereof.
Background technology
Fiberglass reinforced plastics muscle (i.e. gfrp muscle) have compared with reinforcing bar high intensity, corrosion-resistant, fatigue behaviour good and
The advantages of high performance-price ratio, thus there is in civil engineering huge application prospect, but gfrp muscle is existed not compared with reinforcing bar
Foot, its tensile modulus is relatively small, and under identical load operation, the amount of deflection of beams of concrete and fracture width are significantly greater than reinforcing bar and mix
Solidifying Tu Liang.Fiber glass reinforcement is linear elastic materials simultaneously, there is not yielding stage during tension, broken in fragility
Bad so that the ductility of gfrp tendon concrete structure is relatively low, xoncrete structure destroys no obvious sign in use, and material makes
Safety is not high.And steel elastic modelling quantity is higher, there is obvious yielding stage, in this case steel core fiber composite material
The research of material receives attention.This material inner core is made up of metal material and continuous fiber material, so that the two is glued by resin
It is combined, outer layer is then wrapped up by fibrous material and resin.Steel core fibrous composite combines steel and fiber reinforcement in theory
The advantage of material (i.e. frp material), had both solved etching problem in xoncrete structure for the steel and had solved fiber reinforcement plastic
The modulus of material muscle (i.e. frp muscle) is low, the problem of structure ductility difference.
Zheng Bailin et al. proposes the concept that gfrp coats muscle, and inner core is made up of the high ductile material such as steel, and outer layer is by around core

Steel wire is combined as core and fibrous material, is produced using pultrusion molding process, makes many steel strand wires side-by-side by fiber
With resin be wrapped in composite reinforcing center (fibre-reinforced plastic steel twisting-wire composite rib [p]. China: 200610009936.6,
2007.01.17).Several complex forms have some improvement for the performance tool of frp muscle (fiber reinforced plastic rod) above, but
Still suffer from steel core and fibrous material caking property not enough, material discontinuity equalization, using insufficient the problems such as.
Content of the invention
