Polyacrylonitrile Fiber for Concrete Reinforcement | HPM® PAN
High-Performance Micro Synthetic Fiber for Concrete
High-performance micro synthetic fiber engineered for crack control, toughness, and long-term durability in high-performance concrete (HPC) and fiber-reinforced concrete (FRC).
What Is Polyacrylonitrile Fiber for Fiber-Reinforced Concrete?
HPM® PAN is an engineered polyacrylonitrile (PAN) micro synthetic fiber optimized for high-performance concrete reinforcement.
With its ultra-fine diameter, high tensile strength, and superior modulus, it creates a dense 3D micro-reinforcement network inside concrete, delivering:
-
Superior crack control (plastic + drying shrinkage)
-
Impact & toughness enhancement
-
Long-term durability
-
Smooth finishing with no surface fiber exposure
Compared with PP fibers, PAN fibers provide:
-
Higher tensile strength & elastic modulus
-
Better crack-control efficiency
-
More stable performance in HPC/UHPC
-
Better finishing quality

How PAN Fibers Improve Concrete Durability and Crack Resistance
HPM® PAN enhances FRC and HPC through:
-
Formation of a high-density 3D micro-reinforcement matrix
-
Reduced plastic and drying shrinkage cracking
-
Improved toughness, impact resistance, and freeze-thaw durability
-
Smooth finishing with no fiber protrusion
-
Excellent dispersion — no balling or clumping
Enhancing the durability of water conservancy projects
Improving crack resistance, interfacial bonding
Key Benefits of Using PAN Fibers in Concrete

-
High Strength & Modulus for improved toughness
-
Durability in Harsh Environments (freeze–thaw, impact, wear)
-
Uniform Dispersion in concrete mixes
-
Smooth Surface Finish
-
Ideal for HPC, precast, and industrial concrete
Applications of PAN Fiber in High-Performance Concrete
HPM® PAN is ideal for:
-
High-durability slabs, floors & pavements
-
Precast concrete elements
-
Industrial floors and heavy-traffic platforms
-
Waterproof structures: basements, tanks, pools, tunnels
-
Shotcrete for tunnels & underground work
-
Marine & port concrete requiring long-term durability

How to Use PAN Fibers in Concrete Mix Designs
-
Dosage：0.6–1.8 kg/m³（typical: 1.0 kg/m³）
-
Length Selection：
-
6–12 mm → mortar, repair, overlays
-
12–18 mm → standard concrete
-
-
Mixing：Add with aggregates; extend mixing time for uniform dispersion
-
Note：Fibers supplement — not replace — structural steel reinforcement
