Manufacturing process of high-speed rail track slab containing organic reinforced fibers

Abstract

The invention discloses a manufacturing process of a high-speed rail track slab containing organic reinforced fibers. The process includes pre-fabrication of reinforcing ribs containing organic non-metal reinforced fibers, pre-fabrication of organic reinforced fiber concrete, manufacturing of the high-speed rail track slab containing organic reinforced fibers, curing treatment of concrete of the high-speed rail track slab containing the organic reinforced fibers and forming of a finished product of the high-speed rail track slab of the organic reinforced fibers. The track slab has the advantages of being high in anti-shock strength, good in weather resistance, long in service life, good in internal compactness, excellent in frost resistance, excellent in anti-cracking property and the like, the influence of electromagnetic induction caused by metal materials in the high-speed rail or urban railway traffic running process is avoided, and thus the communication security in the high-speedrail or urban railway traffic running process is improved.

Description

technical field [0001] The invention relates to a manufacturing process of a high-speed rail track slab, in particular to a manufacturing process of a high-speed rail track slab containing organic reinforced fibers. Background technique [0002] Fiber-reinforced matrix composites were first developed in the United States in the 18th century. At that time, composite products were mainly to meet the needs of military and aerospace fields. In recent years, based on the many advantages of fiber thermoplastic composite materials, people began to shift the research focus to fiber reinforced thermoplastic or / and thermosetting composite materials, and began to conduct continuous and in-depth research on this type of material. The output of fiber thermoplastic composite materials has gradually increased. It has been applied in many fields, such as aerospace, military industry, automobiles, electronic appliances, bridge building reinforcement, yachts and ships, etc. [0003] Compared...

AI Technical Summary

Problems solved by technology

[0015] The invention provides a manufacturing process for high-speed rail track slabs containing organic reinforced fibers. The purpose is to solve the problems that organic non-metallic fibers will appear after epoxy resin is cured, that is, the problems of increased rigidity and reduced toughness, and at the same time improve the reinforcement of organic non-metallic fibers. The ability of ribs to withstand ultra-low temperature resistance prolongs the service life of organic non-metallic fiber reinforcing ribs used in high-speed rail track panels, and at the same time improves the impact strength of organic non-metallic fiber reinforcing ribs used in high-speed rail track panels
