Chemical and Mechanical Qualities of PVA Fiber

PVA fiber is a synthetic polymer characterized by high hydrophilicity, moderate modulus of flexibility, and strong interfacial bonding with cementitious materials. Unlike steel fibers, which are susceptible to corrosion, or polypropylene fibers, which provide restricted mechanical support, PVA fibers integrate versatility with strength– showing tensile strengths surpassing 1,600 MPa and elongation at break around 6– 8%. Their microstructure enables efficient fracture bridging, energy dissipation, and post-cracking ductility, making them excellent for applications needing strength and effect resistance without jeopardizing workability.
