The fiberglass composite geotextile is a new geosynthetic material, which is made of glass fiber reinforced material, and it is a geosynthetic material made by compounding short staple fiber with needle-punched non-woven fabric. Glass fiber composite geotextile is different from general woven cloth. Its greatest feature is that the intersections of warp and weft are not bent, and each is in a straight state. Bundle the two firmly, can be more uniform and synchronous, withstand external forces, distribution of stress, and when the external force applied to tear the material, the yarn will be concentrated along the initial crack, increasing the tear strength.

When warp-knitting is compounded, warp-knitted bundles are used to repeatedly interpenetrate the fiber layers of warp and weft yarns and staple fiber needled geotextiles to make the three parts together. Therefore, the glass fiber composite geotextile not only has the characteristics of high tensile strength and low elongation, but also has the performance of needled non-woven fabric. Therefore, the fiberglass composite geotextile is a kind of reinforcement that can be used for reinforcement, isolation and protection, and has a three-dimensional overall direction and the average level of a better soil abandon the role of water. Because of its solid matrix and pores are continuous, multi-pore filtering effect, it is a versatile geocomposite. It is the world's high-level application of geocomposite substrate.

Glass fiber composite geotextile application characteristics:
1. As the synthetic fibers currently used for the production of glass fiber composite geotextiles are mainly nylon, polyester, polypropylene, and polyethylene, they all have strong anti-corrosion and anti-corrosion properties.
2. The fiberglass composite geotextile is a water-permeable material, so it has a very good anti-filter isolation
3. as a substrate of non-woven geotextile due to the fluffy structure, with good drainage performance
4. glass fiber composite geotextile has a good resistance to puncture, so it has a very good protection performance
5. glass fiber composite geotextile has a good friction coefficient and tensile strength, with geosynthetic reinforcement

Geotextiles, also known as geotextiles, are water-permeable geosynthetics made from synthetic fibers by needle punching or weaving. The finished product is cloth-like, generally having a width of 4-6 meters and a length of 50-100 meters. Geotextiles are divided into woven geotextiles and non-woven geotextiles. Geotextile has excellent filtration, drainage, isolation, reinforcement, impervious, protective effect, with light weight, high tensile strength, good permeability, high temperature resistance, antifreeze, anti-aging, corrosion resistance.

Geotextile is a new type of building material. The raw material is synthetic fiber of high molecular polymer such as polyester, polypropylene, acrylic, and nylon. According to the manufacturing method, there are two types: spinning geotextiles and non-woven geotextiles. The general engineering is mainly used non-woven geotextiles. The geotextiles have various functions such as seepage prevention, anti-filtration, drainage, isolation, reinforcement, protection, sealing, etc. Compared with the conventional masonry and concrete anti-seepage effect, Low investment, simple construction process, short construction period, good anti-seepage effect, and high channel utilization efficiency.
