Problems solved by technology

However, when fiber-reinforced polymer strips are bonded by this method, not only the reinforcing fibers present in the polymer are damaged and the physical properties are lowered, but also because the polymer strips in the warp direction and the weft direction polymer strips are not in a molten state, So no complete bond is formed between the strips
In addition, since the geogrid of the above-mentioned patent has a planar structure, there are problems of poor friction characteristics and shape stability against vertical loads
[0007] In addition, in the conventional manufacturing method of a fiber-reinforced polymer strip of a geogrid, in supplying a thermoplastic polymer resin in a molten state as a coating material to a plurality of fiber aggregates as an internal reinforcement material, the adhesive force may be Due to the reduction of the type of reinforcement material, there may be problems with the contact point strength of the lattice geogrid

Abstract

The present invention relates to a fiber-reinforced polymer tape having improved durability, the fiber-reinforced polymer tape comprising: a plurality of fiber aggregates as a reinforcing material; a thermoplastic polymer resin as a coating material; and a binder using a powder binder on the surface of the reinforcing material, characterized in that when manufacturing the fiber-reinforced polymer tape, the powder binder is applied around the reinforcing fibers to reinforce the adhesive force with the polymer resin coated on the reinforcing fibers, thereby improving the durability of the fiber-reinforced polymer tape itself.

Description

Technical field [0001] The present invention relates to an improved durability of the fiber-reinforced polymer strip and the use of this trellis geogrid, characterized in that, during the production of fiber-reinforced polymer strips, the reinforcing polymer coating around a polyester-based powder adhesive, covering it with the strengthened fiber reinforced polymer resin adhesion, thereby improving their durability but increases the strength of the contact point of use of this trellis geogrid. Background technique [0002] The present invention relates primarily as a method of manufacturing the geogrid civil reinforcing materials used. [0003] When used in civil construction geogrid reinforced retaining wall, reinforcing bevel, ground enhancement purposes, in addition to having the required high tensile strength, low tensile strain and creep deformation properties, but also required to have resistance, workability, frictional properties and physical properties such as shape stab...
