Example Embodiment

[0052] Example one:

[0053] See attached Figure 1-8 The device of the present invention for forming carbon fiber composite material and bonding and riveting integration with metal plates includes an upper mechanism, a lower mechanism, a driving mechanism, an upper temperature sensor 8, a lower temperature sensor 15, an upper heating channel 6, a lower heating channel 13, and an upper cooling Water channel 6, lower cooling water channel 7, upper pressure sensor 9, lower pressure sensor 16 and control box;

[0054] The driving mechanism, the upper temperature sensor 8, the lower temperature sensor 15, the upper heating channel 6, the lower heating channel 13, the upper cooling water channel 6, the lower cooling water channel 7, the upper pressure sensor 9 and the lower pressure sensor 16 are all controlled by the control box;

[0055] The upper mechanism includes an upper punch 3, a punch, four guide sleeves 5 with the same structure, an upper heating channel 6, an upper cooling wat...

Example Embodiment

[0077] Embodiment two:

[0078] The carbon fiber composite material forming and bonding and riveting integrated device of the present invention is used to prepare a 400mm×400mm×2mm carbon fiber composite material board and a 2mm thick aluminum alloy board bonding riveting piece. 3k carbon fiber is selected as the main body of the carbon fiber composite material. Select phenolic epoxy modified resin for resin matrix;

[0079] The specific method includes the following steps:

[0080] Step 1: Load the carbon fiber prepreg 2 into the mold;

[0081] Operate the drive mechanism to raise the upper mechanism to the highest position, place the formed aluminum alloy plate 1 in the lower concave mold 10; apply a layer of resin adhesive with a thickness of 1mm on the aluminum alloy plate and then spread the carbon fiber prepreg 2. Carbon fiber prepreg 2 is a carbon fiber prepreg with a length of 400mm, a width of 400mm, and a thickness of 0.24~0.26mm. Since the thickness of the test piece is 2m...

Abstract

The invention relates to an integrated device and method for forming of a carbon fiber composite material and sticky-riveting of the carbon fiber composite material and a metal sheet piece, and belongs to the technical field of composite riveting. The technical problems that gaps exist in connecting of the composite material and a metal material, the composite material and an adhesive layer are damaged due to riveting, and the technology procedure is complicated exiting in the prior art are solved. The carbon fiber composite material and metal material sticky-riveting method applying the device comprises the following steps that a carbon fiber prepreg is subjected to die-filling; the carbon fiber prepreg is subjected to gelling; the gelled carbon fiber prepreg and a metal sheet are subjected to die-closing and pressurizing; the carbon fiber prepreg and the metal sheet piece are subjected to heating curing; cooling and die-releasing are conducted; and burrs and flashings at the edge parts when a carbon fiber composite material plate and a metal sheet sticky-riveting test piece are formed are removed. According to the integrated device and method for forming of the carbon fiber composite material and sticky-riveting of the carbon fiber composite material and the metal sheet piece, the effect that bonding can be completed while the carbon fiber composite material is subjected to die-pressing forming is achieved; and the bonding property is effectively improved, and the bonding strength is improved.

Description

technical field [0001] The invention belongs to the technical field of composite riveting, and in particular relates to a device and method for forming carbon fiber composite materials and integrating riveting with metal plate parts. Background technique [0002] Vehicle lightweight technology is a hot research topic in the development of automobiles. The use of new composite materials to replace traditional metal materials is an important way for automobile lightweight. Carbon fiber composite materials have the mechanical properties of high strength, high modulus, high specific strength, and high specific modulus, so that carbon fiber composite materials can realize the lightweight of automobiles without reducing the overall mechanical properties of automobiles. [0003] Carbon fiber composite materials for vehicles have made remarkable progress, but the connection relationship between carbon fiber composite materials and metal materials is complicated. At present, the conn...
