preparation example Construction

[0080] Fabrication process of carbon fiber composite panels with through holes:

[0081]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;

[0082] 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 die 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;

Abstract

The invention discloses a non-rivet riveting die of a carbon fiber composite board and an aluminum alloy board. The non-rivet riveting die comprises an upper punch needle and a rivet overturning needle. The upper punch needle can vertically reciprocate in a blank holder through hole, the rivet overturning needle and the upper punch needle are concentrically arranged, and the rivet overturning needle vertically reciprocates in a lower die through hole. The upper punch needle and the rivet overturning needle are connected with a sensor. By means of data collection, the height adjusting coefficient and the speed adjusting coefficient of the upper punch needle and the rivet overturning needle are obtained, and the height and the running speed of the upper punch needle and the rivet overturning needle are controlled. The invention further discloses a preparing method of the carbon fiber composite board and a non-rivet riveting method of the carbon fiber composite board and the aluminum alloy board. The non-rivet riveting die, the preparing method and the non-rivet riveting method have the characteristics that the large impact force can be borne, the technology step is simple, cost is low, and a riveting connector is superior in pulling resisting, shearing resisting and fatigue resisting performance.

Description

technical field [0001] The invention relates to the field of riveting of a carbon fiber composite material plate and an aluminum alloy plate, in particular to a preparation method of a carbon fiber composite material plate and a rivetless riveting mold and method for the carbon fiber composite material plate and an aluminum alloy plate. Background technique [0002] Nowadays, due to the increasingly serious environmental and energy problems, the lightweight technology of automobiles is developing rapidly. In order to realize the lightweight of automobiles, the use of lightweight, high-strength new materials will be an effective method. Carbon fiber composite material is a new type of composite material with good mechanical properties and has been widely used in aerospace. In recent years, carbon fiber composite materials have been more and more widely used in the automotive industry by virtue of their higher specific stiffness, specific strength, and specific energy absorpt...
