Abstract

The invention discloses a manufacturing process for a high-speed rail plate containing inorganic reinforcing fibers. The process comprises the steps that reinforcing ribs containing inorganic nonmetallic reinforcing fibers are prefabricated, inorganic reinforcing fiber cloth concrete is prefabricated, the high-speed rail plate containing the inorganic reinforcing fibers is manufactured, high-speedrail plate concrete containing the inorganic reinforcing fibers is cured, and the finished high-speed rail plate containing the inorganic reinforcing fibers is obtained. The rail plate has the beneficial effects of high vibration strength, good weather resistance, long service life, good internal compactness, excellent frost resistance, excellent crack resistance and the like and avoids the influence of electromagnetic induction generated in the operation process of the high-speed rail or urban rail transit by using metal materials, and accordingly the communication safety in the operation process of the high-speed rail or urban rail transit 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 inorganic reinforced fibers. Background technique [0002] Fiber-reinforced matrix composites were first developed in the United States in the 1930s. 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 with...
