Forward development method of automobile carbon fiber reinforced composite material covering part

Abstract

The invention relates to the technical field of computer simulation, and particularly relates to a forward development method of an automobile carbon fiber reinforced composite material covering part.The method comprises the steps of material and forming process selection, material spline performance test, initial laying design, product structure design, product structure manufacturability analysis verification and optimization, product structure performance analysis and optimization design, product manufacturing design and data integration, and product test piece production and experiment benchmarking verification development. The forward development process of the automobile carbon fiber reinforced composite material covering part follows the original intention of using a composite material by automobile parts, brings the performance advantages of the composite material into full play, effectively avoids the risk of a forming process, shortens the development period of a product, reduces the development cost of the product to the maximum extent, brings the performance characteristics of CFRP into full play, and achieves light weight and high energy of the product. The product development logic conforms to the automobile light weight trend and the energy conservation and emission reduction concept.

Description

technical field [0001] The invention relates to the technical field of computer simulation, in particular to a forward development method of an automobile carbon fiber reinforced composite material cover. Background technique [0002] With the development trend of automobile lightweight, carbon fiber reinforced composite material (CFRP, Carbon Fiber Reinforced Polymer / Plastic) has become the mainstream material in the research and development of automobile parts due to its light weight, high strength, shock absorption, noise reduction, fatigue resistance and other excellent properties. [0003] At present, the main idea of ​​the research and development of domestic automotive CFRP parts is still based on the original metal parts, equivalent transformation is carried out according to the performance of the metal parts, and the weight reduction goal of the product is achieved through lay-up design and structural changes. [0004] Since CFEP has the characteristics of material ...

AI Technical Summary

Problems solved by technology

Converting the design from metal parts to CFRP parts often adopts the method of over-specification design parts, but this method cannot give full play to the performance advantages of CFRP, and the risk of product molding process, development cycle and development cost are difficult to control, resulting in the use of The original intention of composite materials fell through

[0005] In summary, the existing automotive CFRP parts are based on the original metal parts, and the equivalent transformation of product performance is carried out through lay-up design, structural changes, etc., and there is no formation A set of standardized development process and design specifications is in the exploratory stage, and it is difficult to control the risk of product molding process, development cycle and development cost, and the performance of materials cannot be fully utilized
