Abstract

The invention is a carbon fiber subway window frame with a foam sandwich structure. The carbon fiber subway window frame includes a foam sandwich core and a carbon fiber skin coated outside the foam sandwich core. The invention also discloses a manufacturing method of the carbon fiber subway window frame. It includes the following steps: (1) Foam sandwich bonding molding; (2) Carbon fiber skin laying; (3) Autoclave process molding. The invention adopts the carbon fiber foam sandwich structure to replace the metal material of the aluminum alloy prototype car, which can not only effectively reduce the weight of the subway window frame, achieve the purpose of light weight, but also reduce energy consumption and prolong the service life.

Description

technical field [0001] The invention relates to the field of subway vehicles. In particular, a carbon fiber subway window frame with a foam sandwich structure and a manufacturing method thereof. Background technique [0002] The traditional subway car body is mostly made of aluminum alloy and other metal materials, which not only has a large weight, but also has disadvantages such as poor corrosion resistance and short service life. Due to the characteristics of high specific strength and high specific modulus, low density, small thermal expansion coefficient, strong fatigue resistance and damage resistance, carbon fiber composite materials have been greatly developed in the field of rail transportation. Now the subway window frame is replaced by the metal material of the aluminum alloy prototype car with carbon fiber composite material, which plays an important role in reducing the weight of the subway car body, reducing noise, vibration, improving safety, and reducing mai...
