Abstract

The invention provides a method of forming a fiber-aluminum alloy composite part. The method comprises the following steps: 1, cutting an aluminum alloy plate and a fiber cloth according to a shape ofthe part; 2, subjecting the aluminum alloy plate to solid solution treatment, and immediately subjecting the aluminum alloy plate from the solid solution treatment to pre-pressing treatment, allowingfor uniform distribution of gridded grooves on a surface, glued to the fiber cloth, of the aluminum alloy plate, and then subjecting the pre-pressed aluminum alloy plate to quenching treatment; 3, subjecting the quenched aluminum alloy plate to degreasing treatment, and subjecting the fiber cloth to pre-impregnation treatment in an epoxy resin glue solution; 4, forming a sandwich plate in the order of aluminum alloy plate, fiber prepreg and aluminum alloy plate, and pre-pressing the sandwich plate; and 5, putting the obtained sandwich plate into a stamping die, closing the die and holding thetemperature, and then carrying out solidification to obtain the fiber-aluminum alloy composite part. The method overcomes the shortcoming of low elongation rate during the formation of a fiber material and improves the strength of the composite material part.

Description

technical field [0001] The present application relates to the technical field of composite materials, in particular to a method for forming fiber-aluminum alloy composite parts. Background technique [0002] Due to the advantages of high specific strength, specific stiffness and good corrosion resistance, fiber-reinforced resin-based composite materials are widely used in aerospace and automobile and other transportation fields. However, the inherent defects of the resin itself, such as: easy aging, easy creep, poor flame resistance and other shortcomings, these defects limit the further application of fiber-reinforced resin-based composite materials. In order to overcome these shortcomings of the resin matrix, aluminum alloys can be combined with fiber composite materials, so that while overcoming the weakness of poor heat and humidity resistance, the characteristics of good plasticity, impact resistance and ease of processing of aluminum alloys can be brought into play. I...
