Embodiment Construction

[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0015] The enhanced composite material skirt plate for rail cars provided by the present invention uses a new material with light weight and excellent performance to replace the original material design, that is, the composite material under the new process is used, and its structure replaces the existing aluminum alloy structure. apron. The new material, that is, the composite material structure provided by the present invention, can adopt various forming techniques, and is composed of glass fiber and carbon fiber hybrid composite material. The reinforced composite skirt for rail vehicles of the present invention will be further described below in conjunction with specific embodiments.

Abstract

The invention discloses a railcar-use enhanced composite material skirt-board which is prepared by using a composite material comprising 4 raw materials such as foam, a resin system, glass fiber, and carbon fiber. Foam, the resin system, and glass fiber are main raw materials, and the carbon fiber is an enhancing material. The carbon fiber is added to positions of a prepared part with more stress. The glass fiber and the carbon fiber are both applied in a form of paved layer. The whole railcar-use enhanced composite material skirt-board is manufactured through one-step shaping.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a reinforced composite material skirt plate for rail vehicles. Background technique [0002] In recent years, China's rail car technology has developed rapidly and achieved leapfrog development. [0003] With the increase of the speed of rail cars, some problems have gradually appeared in the actual use of rail cars, which affect the safety of the vehicles and constitute hidden dangers. Among them, due to the heavy weight of the reinforced composite skirt for rail cars, the frequency vibration and the acceleration of gravity of the reinforced composite skirt for rail cars lead to lock cracks and lock pin fractures. The problem of material skirt falling off on equipment has become one of the more prominent problems. Contents of the invention [0004] In view of this, the present invention provides a new reinforced composite skirt for rail vehicles, which has sufficient rigid...
