Fiberglass substitute for steel fibers, this product is designed as an alternative to steel fibers while also incorporating some characteristics of synthetic fibers. Compared to steel fibers, it boasts features such as corrosion resistance, easy dispersion, ease of application, and non-damaging to mixing equipment. The product is made from synthetic resins, processed through special technology and surface treatment, and exhibits high tensile strength, good dispersion in concrete, and strong adhesion. It replaces steel fibers in cement concrete, overcoming the drawbacks of low tensile strength, small ultimate elongation, and brittleness. It possesses properties such as tensile, shear resistance, crack resistance, fatigue resistance, and high toughness, and has been applied in construction, road and bridge, and hydraulic engineering fields.
