Basalt fibre composite rib and basalt fibre composite inhaul cable

Abstract

The invention discloses a basalt fibre composite rib and a basalt fibre composite inhaul cable. The composite rib is formed by drawing, extruding, molding and compounding basalt fibre and carbon fibre under the pretension action, and fibre volume ratio is 4:1-1:1; the basalt fibre composite inhaul cable comprises an outer protecting layer and fibre reinforcement material arranged in the outer protecting layer, the fibre reinforcement material comprises a center rib and an outer rib, the center rib is composed of a basalt fibre rib or carbon fibre rib, the outer rib is composed of the basalt fibre composite rib, an adhesive elastic filling layer and an inner sleeve are arranged between the center rib and the outer rib, the inner side of the inner sleeve is connected with the adhesive elastic filling layer, and the outer side of the inner sleeve is connected with the outer rib. In the composite inhaul cable, the carbon fibre content occupies 25-40 percent of total fibre content of the inhaul cable. Compared with the prior art, the composite carbon fibre of the basalt fibre composite inhaul cable in the basalt fibre enables short-period and long-period mechanical property and chemical property of the inhaul integer to be better, and has remarkable economy.

Description

technical field [0001] The invention relates to a fiber reinforcement and a cable made of the fiber reinforcement, and belongs to the development of new structural materials and structural forms in related fields such as civil engineering and transportation. Background technique [0002] Fiber Reinforced Polymer (FRP) is a high-performance material formed by mixing fiber materials and matrix materials in a certain proportion and compounding them through a certain process. This material came out in the 1940s and was initially used in high-tech fields such as aviation, aerospace, and national defense. Later, it was widely used in automotive, chemical, and medical fields. In recent years, due to its advantages of high strength, light weight, and corrosion resistance, it has been widely used in civil engineering structures and has attracted extensive attention from the engineering community. [0003] Due to its light weight, high strength, corrosion resistance, easy cutting and...

Problems solved by technology

However, due to the continuous high price of carbon fiber for many years, if carbon fiber is to be adopted on a large scale, the cost of the project will inevitably be greatly increased. Therefore, the research and application of carbon fiber cable stays are limited and restricted by actual economic factors.

Also, carbon fiber cables are more prone to vibrating under wind and other dynamic loads due to their inherently low mass, which is also a disadvantage

At the same time, the brittleness problem also needs to be improved
