Polyacrylonitrile Fiber for Concrete Reinforcement | HPM® PAN
High-Performance Micro Synthetic Fiber for Concrete
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 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

Looking for Cost-Effective High-Performance Concrete Reinforcement?
High-performance fibers such as PVA fiber, basalt fiber, carbon fiber, and aramid fiber are widely used in high-performance concrete (HPC) and UHPC.
They deliver excellent strength and toughness—but in real projects, their high cost limits large-scale application, making them suitable mainly for specialized or high-end use.
