- Current and potential applications
What are Macro Synthetic Fibres?
- Available commercially since the early 2000s
- Intended to be used as a replacement for steel mesh reinforcement and not for structural steel design.
- Manufactured from polymeric material such as polyolefin e.g. polypropylene or polyethylene, polyester, nylon, pva, polyacrylic, aramids and blends of them.
- Fibre classification:
- Class Ia: < 0.3 mm diameter, mono-filamented
- Class Ib: < 0.3 mm diameter, fibrillated
- Class II: > 0.3 mm diameter
- Tensile strength of polymers range from 100 – 650 MPa
- Elastic Modulus of 2 – 10 GPa
- Dosage rates range from 2 – 10 kg/m3
