Problems solved by technology

[0005] In order to solve the problem that there is no new connection method that can meet the dual requirements of reliable connection strength and easy implementation of standardization at the same time, it is impossible to realize the connection between carbon fiber material parts and car body frame steel structure, resulting in the inability to produce a new generation of carbon fiber light rail trains To solve the technical problem of the whole vehicle body, the invention provides a bonding process for carbon fiber parts of light rail vehicles

Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] Such as Figure 1 to Figure 2 Shown, light rail car carbon fiber part bonding process of the present invention comprises the steps:

[0024] Step 1: Select a stable construction environment with an ambient temperature range of 15°C to 30°C and a relative humidity range of 30% to 70%;

[0025] Step 2: Grind the surface of the bonded end face to be assembled on the carbon fiber component: use No. 240 sandpaper to cross-grind along the grinding direction at an angle of ± 45° to the extending direction of the bonded end face;

[0026] Step 3: Use a primer to evenly coat the bonded end faces of the carbon fiber parts after grinding in step 2;

[0027] Step 4: Use the 1-A-05-4-H6-Ts type industrial rubber sheet to make multiple glue thickness positioning blocks 1, the length and width of the positioning block 1 are both 10 mm, and the thickness is 5 mm;

Abstract

The invention relates to a process for bonding carbon-fiber components of light rail vehicles and belongs to the field of methods for connecting and mounting between the carbon-fiber components of the light rail vehicles and vehicle body steelwork skeletons. According to the process, edges of the carbon-fiber components to be assembled are compacted by using a pair of F-shaped forceps, the thickness of coating of glue liquor is limited through a glue liquor thickness locating block, and thus, the components made from carbon fiber materials and vehicle body skeleton steelwork can be subjected to integral bonding; and the bonded carbon fiber components and the corresponding steelwork skeleton are integrally integrated fixedly in a tightening adhesive tape wound and bound manner. According to the bonding process disclosed by the invention, the condition that the thickness of the glue liquor is uniform and the bonding effect is firm and reliable can be ensured, so that a bran-new way for producing entire vehicle bodies of carbon-fiber light-rail trains of a new generation is opened up.

Description

technical field [0001] The invention belongs to the field of connection and installation methods between carbon fiber components of light rail vehicles and steel structure skeletons of vehicle bodies, and in particular relates to a bonding process of carbon fiber components of light rail vehicles. Background technique [0002] The complete vehicle body of a light rail train usually includes two types of aluminum alloy vehicle body and stainless steel vehicle body. , forming a whole. The stainless steel vehicle body is to form a whole by mechanically connecting or welding the steel frame of the car body and the stainless steel plate. [0003] At present, in order to further reduce the weight of the vehicle, increase the running speed of the light rail vehicle and reduce energy loss, a new generation of carbon fiber light rail vehicle body form is being developed. The core content is to use carbon fiber materials to replace the original aluminum-plastic panels or Stainless s...
