Embodiment Construction

[0031] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The embodiments are only used to explain the present invention and do not limit the protection scope of the present invention.

[0032] Such as Figure 1-3 As shown, the present invention is a carbon fiber composite subway car body formed by a low-cost process. The car body includes a carbon fiber outer skin 1, a carbon fiber inner skin 2, and is laid on the carbon fiber outer skin 1 and the carbon fiber inner skin 2. Between the honeycomb sandwich layer 3, the sandwich layer 3 is formed by splicing honeycomb 7, foam 8 and several vertical and horizontal stiffeners 6, door frame 4, window frame 5, said sandwich layer 3 and carbon fiber outer skin 1 and the carbon fiber inner skin 2 are integrally solidified and formed by the adhesive film link. The carbon fiber outer skin 1, the carbon fi...

Abstract

The invention discloses a low-cost technologically-molded carbon fiber composite material subway vehicle body and a manufacturing method thereof. The subway vehicle body comprises a carbon fiber outer covering, a carbon fiber inner covering, and a sandwich layer paved between the carbon fiber outer covering and the carbon fiber inner covering. The invention also discloses a manufacturing method of the carbon fiber composite material subway vehicle body, which comprises the following steps: (1) paving and adhering carbon fiber fabric prepregs, carrying out OOA technological molding on carbon fiber outer covering; (2) paving honeycombs, foams and pre-modled pre-embedded parts on the carbon fiber outer covering to be used as the sandwich layer, and carrying out OOA technological molding on the sandwich layer; (3) paving and adhering the the carbon fiber fabric prepregs on the sandwich layer, and carrying out OOA technological molding on the carbon fiber inner covering, i.e. integration on the vehicle body. According to the low-cost technologically-molded carbon fiber composite material subway vehicle body and a manufacturing method thereof disclosed by the invention, the weight of the subway vehicle body is effectively reduced, the aim of the lightweight of the vehicle body is fulfilled, the energy consumption of the vehicle body is reduced, and the service life of the vehicle body is prolonged; moreover, by adopting the OOA molding technology with low cost, the cost of the molded carbon fiber composite material subway vehicle body is greatly reduced.

Description

Technical field [0001] The invention relates to the technical field of subway vehicles, in particular to a carbon fiber composite subway car body formed by a low-cost process and a manufacturing method thereof, so as to achieve the purpose of lightweight subway car body. Background technique [0002] The subway car body is used to accommodate passengers, passengers, luggage, etc. and to install various equipment components. It is supported by bogies and mainly plays a bearing role. It is the main component of rail vehicles. The existing subway car body mostly uses metal materials. The car body is composed of three parts: the side walls and the roof. It has disadvantages such as high weight, high cost, high energy consumption, poor corrosion resistance, and short service life; general car body bearing structure The weight of the vehicle is about 20%-25% of the total weight of the vehicle. Therefore, it is of great significance to effectively reduce the weight of the vehicle body a...
