Concrete fibre--- polyacrylonitrile (PAN) fiber

Polyacrylonitrile  fiber, also known as PAN fiber, is a synthetic fiber. Its performance characteristics are mainly reflected in the following aspects:

High elastic modulus and tensile strength: Compared with polypropylene fiber, polyacrylonitrile fiber has a higher elastic modulus (>8500Mpa) and tensile strength (>530Mpa), which enables it to provide better reinforcement effect in concrete.

Excellent weather resistance: Polyacrylonitrile fiber has good weather resistance, including resistance to UV rays, high temperature and severe cold. These characteristics enable it to maintain good performance under various environmental conditions and will not age rapidly or degrade due to temperature changes.

Improve the crack resistance of concrete: Polyacrylonitrile fiber can significantly improve the flexural toughness, fatigue strength and flexural tensile strength of concrete, thereby improving the early crack resistance of concrete. This is of great significance to improving the safety and durability of concrete structures. ‌

Suitable for a variety of engineering applications: Due to its excellent performance, polyacrylonitrile fiber is widely used in high-performance concrete road pavements, bridge panels, airport pavements, rockfill dam panels, earthquake and explosion-proof projects, and has become an ideal anti-cracking reinforcement material.
