Vehicle and supporting components thereof as well as production method of supporting components

Abstract

The invention belongs to the technical field of vehicles and particularly provides a vehicle and supporting components thereof as well as a production method of the supporting components. The invention aims at effectively ensuring the support strength of carbon fiber parts and avoiding the problem of larger weight of existing metal support parts by utilizing the advantages of good mechanical properties of carbon fiber composite materials along the direction of fibers. Therefore, the supporting components comprise a plurality of laminated carbon fiber layers; because the carbon fibers belong toanisotropic materials, the strength of the carbon fibers along the fiber direction is far greater than the strength perpendicular to the fiber direction while the supporting components often bear a variety of loads; therefore, the supporting components set the fiber laying direction of two adjacent carbon fiber layers in a plurality of carbon fiber layers to be different from each other, and further the supporting components can better withstand different loads from all directions, and the strength and the stiffness of the supporting components can be effectively ensured while the lightweightof the vehicle is realized, and further the safety performance of the vehicle is effectively ensured.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and specifically provides a vehicle, a support member thereof, and a manufacturing method of the support member. Background technique [0002] With the continuous reduction of earth's energy, the existing vehicle technology field pays more and more attention to the energy consumption of vehicles, and as an important means of reducing energy consumption, reducing the weight of vehicles has always been the most respected method by technicians. In order to reduce the weight of vehicles, many existing vehicles, especially electric vehicles, have begun to use carbon fiber parts. Specifically, the use of carbon fiber parts on vehicles can well meet the lightweight requirements advocated in the field of vehicle technology, and the reduction of vehicle weight can not only improve the overall performance of the vehicle, but also effectively reduce the energy consumption of the vehicle; Therefore, more a...

AI Technical Summary

Problems solved by technology

Traditional metal materials are isotropic materials, while carbon fiber composite materials are anisotropic materials. Although their mechanical properties along the non-fiber direction are poor, their mechanical properties along the fiber direction are very good.
