Building Reinforcement Materials

Bi-component coarse denier filament non-woven fabric (BCDFNF) is a high-performance composite material designed for structural reinforcement in construction. Comprising two polymer components (e.g., PP/PE or PET/PA) with thick, durable filaments (coarse denier), it offers superior tensile strength, crack resistance, and dimensional stability. Manufactured via melt-spinning technology, BCDFNF forms an interlaced web structure that enhances concrete integrity and load-bearing capacity. Its applications include bridges, tunnels, and buildings, where it mitigates cracks, improves durability, and reduces corrosion. Lightweight yet robust, BCDFNF simplifies installation, cuts labor costs, and supports thermal insulation. Eco-friendly and recyclable, it aligns with sustainable construction practices, making it ideal for retrofitting and new projects.

Ultra-High Tensile Strength


Engineered with dual-polymer filaments (PP/PE or PET/PA) and a coarse denier structure (≥15 denier), this fabric delivers tensile strength exceeding 2,500 MPa—2-3 times higher than conventional reinforcement materials. Its interlaced web design distributes stress evenly, ensuring superior load-bearing capacity in concrete structures.


Crack Mitigation Technology


The fabric’s dense network of filaments reduces crack propagation by up to 70%, according to lab tests. This feature is critical for earthquake-prone regions or high-traffic infrastructure, significantly extending service life and minimizing maintenance costs.


Chemical & Thermal Resistance


Withstanding temperatures from -40°C to +120°C and resisting acids, alkalis, and UV radiation, it maintains structural integrity in harsh environments. Ideal for coastal or industrial projects where corrosion is a risk.


Eco-Friendly & Recyclable


Composed of 100% recyclable polymers, it supports circular economy goals. Its lightweight design (80-150 g/m²) cuts transportation emissions and waste by 30% compared to traditional steel mesh.


Multi-Functional Applications


Used in bridges, tunnels, and high-rise buildings, it doubles as a thermal insulator (R-value: 0.8-1.2 m²·K/W) and moisture barrier. Tailored thickness options (0.5-2 mm) adapt to diverse project needs.

Product Uses

Product Uses


Bridges & Highways

Used in concrete decks and pylons to reinforce load-bearing structures, this fabric reduces crack formation by 70% under dynamic traffic loads. Its 2,500+ MPa tensile strength and chemical resistance protect against de-icing salts and environmental stress, extending service life by 15–20 years.


Tunnels & Underground Infrastructure

Installed as a composite liner, it prevents moisture penetration and structural deformation in tunnels. The fabric’s 0.035 W/(m·K) thermal conductivity stabilizes temperature variations, while its B1 fire rating meets safety standards for metro systems.


High-Rise Buildings

Lightweight yet robust, it replaces traditional steel mesh in curtain walls and shear walls, reducing construction weight by 30%. Ideal for seismic zones, its crack-mitigation properties enhance structural integrity during earthquakes.


Industrial Floors

Applied in warehouses and factories, the fabric’s acid/alkali resistance safeguards concrete floors from chemical spills. Its 150 g/m² thickness provides a durable, anti-fatigue layer under heavy machinery.


Coastal & Offshore Structures

Resistant to saltwater corrosion and UV radiation, it reinforces seawalls and offshore platforms. Tested in ASTM D638 salt spray conditions, it maintains 98% tensile strength after 5,000 hours of exposure.


Retrofitting Projects

Used to strengthen aging concrete in historical buildings, it adheres seamlessly to existing structures. Its eco-friendly recyclability aligns with sustainable renovation goals, cutting material waste by 40%.


FAQ

FAQ
