Abstract
Fiber reinforced plastic (hereinafter called FRP for short) reinforcing material is an improvement to original FRP material. The utility model provides a fiber reinforced plastic reinforcing material, including a FRP core layer and a basic resin to dip FRP reinforcing material. The periphery of core layer is wrapped with bulk glass yarn reinforced plastic envelop in axial direction. The fiber reinforced plastic made from this utility model, because of bulk glass yarn reinforced plastic envelop at periphery, improves bondability with concrete, and hence prolongs service life of reinforced concrete components. Therefore, the utility model can replace reinforcement to strengthen concrete. the utility model is widely applied to buildings under severe environment, for example, sea works, parking spots using antifreezing agent and bridges etc.
Description
Technical field
Fibre reinforced plastics (hereinafter to be referred as FRP) muscle material belongs to the improvement to original FRP muscle material.
Background technology
Traditional FRP muscle material is to be sandwich layer with the fiber roving, the impregnation matrix resin after formed by extrusion and tension make.It has high-strength light, corrosion-resistant, low conduction, designability, advantage such as close with concrete linear expansion coeffcient, progressively replace reinforcing bar in recent years and be used for strengthening concrete, be widely used in the building in the harsh and unforgiving environments, as marine structure, the parking lot of using antifreezing agent and bridge or the like.In these engineerings, FRP muscle material and concrete adhesive property or be referred to as and concrete bond stress receive much attention as an important The Concrete Structure Design parameter.So in order to improve FRP muscle material and concrete bond stress, be everlasting before the matrix resin curing that fiber wall with strong rib material of plastic flooded, evenly be stained with one deck sand grains by the scab machine on muscle material surface, to increase the roughness on muscle material surface.But, under certain loading, sand grains tends to come off from its bonding interface with FRP muscle material, thereby causes FRP muscle material and the reduction of concrete bond stress, it is unexpected that property destruction take place in the bonding of sand grains and muscle material, thereby reduce the application life that strengthens concrete component greatly.
Summary of the invention
At the problem of above-mentioned existence, the utility model proposes a kind of fiber wall with strong rib material of plastic of novel structure, can increase the roughness of sandwich layer appearance effectively, improve and concrete bond stress, thereby improve the application life that strengthens concrete component.
Technical solution of the present utility model is: a kind of fiber wall with strong rib material of plastic is provided, comprise the matrix resin that fibre reinforced plastics sandwich layer and fiber wall with strong rib material of plastic are flooded, at its sandwich layer outer peripheral face, axially be wrapped in bulked glass yarn reinforced plastic covering.
Fiber in the sandwich layer is one of following type: 1) carbon fiber; 2) alkali-free glass fibre; 3) high strength glass fiber; 4) aramid fiber; 5) two or more any combination, its fiber volume fraction is 40%-70%.Selecting the fiber of one of above type for use, mainly is the characteristics of utilizing its hot strength high, and the mechanical strength of fiber wall with strong rib material of plastic is provided, and satisfies the requirement of strength in the use.
Fiber in the covering is one of following type: 1) high strength glass fiber buiky yarn; 2) alkali-free glass fibre buiky yarn; 3) above-mentioned two kinds combination, its fiber volume fraction is 30%-60%.
At the sandwich layer outer peripheral face, axially the bulked glass yarn reinforced plastic covering of parcel is the crude surface that has utilized buiky yarn, increases the surface roughness of fiber wall with strong rib material of plastic, improve and concrete bond stress, thereby improved the application life that strengthens concrete component.
The matrix resin that fiber wall with strong rib material of plastic flooded is a thermosetting resin, can be one of following type: 1) epoxy resin; 2) epoxy vinyl ester resin; 3) unsaturated polyester resin.
Also can have spiral helicine concavo-convex distortion at muscle material covering external surface.
As everyone knows, bulked glass yarn is a glass continuous filament yarn, the fluffy glass fiber yarn that it is formed by expanded (distortion).It has not only kept the general performance of simple glass fiber, and have both the intensity of continuous glass fibre and the bulkiness of short fiber, the fiber wall with strong rib material of plastic that adopts the utility model to make, because at the sandwich layer outer peripheral face, axially be enclosed with bulked glass yarn reinforced plastic covering, therefore it can increase the roughness of fiber wall with strong rib material of plastic sandwich layer appearance effectively, has improved and concrete bond stress, thereby has improved the application life that strengthens concrete component.
