Problems solved by technology

[0015] The invention provides a manufacturing process of high-speed rail track slabs containing reinforced fiber cloth. The purpose is to solve the problems of increased rigidity and reduced toughness of conventionally manufactured high-speed rail track slabs after epoxy resin curing, and at the same time improve the resistance of reinforcing ribs. The ability of ultra-low temperature resistance prolongs the service life of the ribs used for high-speed rail track panels containing reinforced fiber cloth, and at the same time improves the impact strength of ribs used for high-speed rail track panels containing reinforced fiber cloth

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 reinforced fiber cloth. 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 ther...
