preparation example Construction

[0069] Fabrication process of carbon fiber composite panels with through holes:

[0070] 1. After the carbon fiber cloth prepreg process is completed, the carbon fiber composite material prepreg cloth is cut, and the prepreg cloth is placed into the groove in the lower die 120. During the laying process, the woven carbon fiber composite material prepreg cloth is The weaving pores of the lower die 120 pass through the beam of light, and ensure that the carbon fiber composite material prepreg is completely paved in the groove, and there is no gap between the bottom surface of the groove and the carbon fiber composite material prepreg;

[0071] 2. Assemble the upper punch 110 and the lower die 120 together, and heat the combined mold consisting of the upper punch 110 and the lower punch 120 together to perform prepreg gelation. Taking novolac epoxy vinyl resin as an example, raise the mold clamping temperature to 100°C-110°C to complete the gelation process of the resin;

Embodiment

[0138] Apply the method for preparing a carbon fiber composite material plate with a through hole according to the present invention to prepare a central through hole with a diameter of 8mm, and the overall size of the carbon fiber composite material plate is 200mm×80mm×2mm. The base material of the prepared carbon fiber composite board is phenolic epoxy vinyl resin, and the reinforcement material is 3k carbon fiber filament.

[0139] The steps of the self-piercing riveting method between the aluminum alloy plate and the carbon fiber composite plate comprising the preparation process of the carbon fiber composite material plate with through holes described in the present invention are as follows:

[0140] 1. Take an aluminum alloy plate 160 with a thickness of 2mm;

[0141] 2. Prepare a carbon fiber composite material plate 150 with a through hole with a diameter of 8 mm. Cut the prepreg cloth into 8 cuboids with a size of 200 mm × 80 mm, and spread the cut carbon fiber prepr...

Abstract

The invention discloses a self-punching riveting die for a carbon fiber composite plate and an aluminum alloy plate. The self-punching riveting die comprises a rivet which is used for riveting the carbon fiber composite plate and the aluminum alloy plate, a punch which can reciprocate vertically in a through hole of a blank holder, and a female die body. Female die cavities in the center position of the female die body are concentrically formed with the punch. The side walls of the female die cavities are unthreaded hole cylindrical side walls, and cone bosses are arranged in the centers of the female die cavities. Unthreaded holes and the conical bosses are riveted and matched. The punch and the female die body are connected with a sensor, and height adjusting coefficients, speed adjusting coefficients and timing adjusting coefficients of the punch are obtained by collecting data. The invention further discloses a preparing method for the carbon fiber composite plate and a self-punching riveting method for the carbon fiber composite plate and the aluminum alloy plate. The self-punching riveting die and method for the carbon fiber composite plate and the aluminum alloy plate have the characteristics that large impact force can be borne, technology steps are simple, cost is low, and tensile, shearing resistance and fatigue resisting performance of a riveting connector are superior.
