Embodiment Construction

[0025] The same reference numbers used in the figures denote identical or technically equivalent elements.

[0026] The terms "longitudinal" and "transverse" respectively denote that an element extends along a given direction and in a plane perpendicular to this direction. "Cross-section" refers to a section perpendicular to the "longitudinal" direction.

[0027] The following will be described in sequence: (1) the embodiment of the composite material sleeper; and (2) the embodiment of the method for manufacturing the composite material sleeper.

[0028]

[0029] see figure 1 . figure 1 A schematic perspective view of a composite sleeper according to an embodiment of the invention is shown. Sleepers include along the longitudinal direction (such as figure 1 The basic profile 1 extending in the direction indicated by the middle arrow). The base profile 1 has a cavity extending through it in the longitudinal direction. The cavity may be empty or filled with a core 2 to p...

Abstract

The invention discloses a railway sleeper made of composite materials and a manufacturing method of the railway sleeper. The railway sleeper comprises a basic section bar extending in the longitudinal direction. The basic section bar is provided with a cavity passing through the basic section bar in the longitudinal direction. The basic section bar is made of a fiber-reinforced resin matrix composite material. The fiber-reinforced resin matrix composite material comprises resin and a fiber-reinforced material. The fiber-reinforced material comprises fiber felt and a plurality of pieces of fiber yarn. The fiber felt is laid around the cavity in the basic section bar. The fiber yarn pieces are distributed nearby the fiber felt in the longitudinal direction. Moreover, the fiber felt is laid into a unit in the basic section bar or a plurality of units arranged in sequence from the inner layer to the outer layer of the basic section bar. Each unit of the fiber felt comprises a plurality of pieces of fiber felt which are laid around the cavity.

Description

technical field [0001] The invention relates to the field of composite materials, and is especially suitable for composite material sleepers supporting steel rails in railway lines. Background technique [0002] Sleepers are an indispensable material in the field of railway transportation. Its function is to support under the rails, maintain the gauge, level, height and direction between two or more strands of rails through interconnected parts, and make the various loads on the rails evenly distributed on the ballast bed basically. Therefore sleepers must have firmness, durability and elasticity. [0003] Sleepers used in railway construction projects include: wooden sleepers, reinforced concrete sleepers and steel sleepers. [0004] Known wooden sleeper rails are widely used on special sections such as bridges and turnouts due to their good elasticity, ease of processing, and convenience in use. However, due to the reason of material selection, the strength and durabil...
