New direction: Basalt fiber composite materials for polymer bridge frames

November 07, 2024

Basalt fiber, a high-performance fiber made by drawing natural basalt ore after high-temperature melting, is gradually becoming the new favorite of industrial materials due to its excellent physical and chemical properties. It not only has high strength, high modulus, high temperature resistance, corrosion resistance and other characteristics, but also has good electrical insulation and UV resistance. These characteristics make basalt fiber composite materials have broad application prospects in polymer bridge structures.

Polymer cable trays, as infrastructure in industries such as power and communication, have extremely strict requirements for material performance. Although traditional metal cable trays have strong load-bearing capacity, they are prone to corrosion, heavy, and have high maintenance costs. The emergence of basalt fiber composite materials has brought new solutions to this field.

The cable tray made of basalt fiber as a reinforcing material, supplemented with resin matrix such as unsaturated polyester resin and epoxy resin, and other additives, has the characteristics of wide application, high strength, light weight, reasonable structure, low cost, long service life, strong corrosion resistance, simple construction, flexible wiring, standard installation, and beautiful appearance. It brings convenience to technical transformation, cable expansion, maintenance and repair.
