Abstract

The invention discloses a carbon fiber metro vehicle body chassis and a manufacturing method thereof. The metro chassis comprises transverse ribs, lower skin, an interlayer honeycomb material and upper skin, wherein the lower skin is attached to the transverse ribs in a laid manner, and the interlayer honeycomb material is placed between the upper skin and the lower skin. The invention further discloses the manufacturing method of the carbon fiber metro chassis. The manufacturing method comprises the following steps of 1, laying and attaching the transverse ribs of the chassis, and embedding a foaming material into groove areas of the transverse ribs; 2, laying and attaching the lower skin, and laying and attaching a reinforcing layer to a specified layer; 3, connecting wiring pipes with the honeycomb material in a bonding manner, and conducting pore filling well; and 4, laying and attaching the upper skin, and laying and attaching a reinforcing layer to a specified layer. In the process, the transverse ribs, the upper skin and the lower skin are cured through an OOA process, wherein the transverse ribs and the lower skin are integrally cured. Different from traditional aluminum alloy materials and stainless steel materials, the metro chassis made of the carbon fiber material is high in bearing capacity, good in rigidity, small in self weight, excellent in impact resistance and long in service life.

Description

technical field [0001] The invention relates to the technical field of subway vehicles, in particular to a carbon fiber subway car body underframe and a manufacturing method thereof. Background technique [0002] In recent years, affected by the rising cost of metal materials and their excessive weight, and due to the continuous development and evolution of composite materials, for example, the subway has a tendency to use carbon fiber composite materials, because carbon fiber materials have light weight, high strength and elasticity. Excellent characteristics, its deformation rebound ability, energy absorption and release efficiency far exceed steel and aluminum alloy materials. [0003] The existing subway underframe mainly uses metal materials, which have the disadvantages of heavy weight, poor corrosion resistance, and short service life. Carbon fiber materials have the characteristics of high specific strength and specific modulus, excellent mechanical properties of pa...
