Project Background:
Traditional communication and power grid steel tower have the problems of difficult transportation and high transportation cost in remote mountainous areas, and composite material because of its excellent comprehensive performance, such as high strength, light weight, corrosion resistance, good insulation and other characteristics, communication and power industry in various countries to a high degree of attention. In special working conditions, composite lattice tower is a useful supplement to the existing communication and transmission tower.
Aims & Goals:
Outcomes: 1. To optimize the fiber and matrix materials for lattice towers, and reduce the total mass of lattice tower by ≥25% compared with metal one;
2. To study composite lattice tower structures design, and reduce the use of metal connectors in lattice tower;
3. To decrease single-piece mass of composite tower components, and enhance the connection strength.
1. Developed GFRP profile with excellent mechanical properties and durability.
2. Design a novel connection structure with mortise and tenon joints and bolt joints, with a tensile strength greater than 50Mpa.
3. Completed the design and installation of GFRP lattice tower, achieving a weight reduction of 25% compared to metal one and reducing floor area by 10%.
DEMONSTRATION："Green Lattice Tower" made from FRP composite, substituting emission-intensive materials like steel, was built in Egypt by NEXCEL project team.
