Problems solved by technology

Under normal circumstances, splicing is carried out with foamed rubber film. The splicing of foamed rubber film is characterized by excess strength and stiffness at the splicing position, and obvious discontinuity of dielectric properties in the spliced ​​area. Excessive stiffness causes the loss of overall structural strength. Electrical discontinuity causes localized electrical performance degradation

Abstract

The invention provides a spliced honeycomb plate and a manufacturing method thereof. The spliced honeycomb plate comprises a first skin, a honeycomb core and a second skin; wherein the honeycomb corecomprises a first honeycomb part, a second honeycomb part and an adhesive layer. A first connecting groove is formed in part of the first honeycomb part of the honeycomb core; a second connecting groove is formed in part of the second honeycomb part of the honeycomb core, a connecting part of the first honeycomb part of the honeycomb core and the second honeycomb part of the honeycomb core is an overlapping area, and the first connecting groove of the honeycomb core and the second connecting groove of the honeycomb core are located in a honeycomb core overlapping area. According to the splicedhoneycomb plate, one part of the first honeycomb part and one part of the second honeycomb part are connected in a stacked mode to form the overlapped area, so that the physical performance and the chemical performance of the overlapped area are basically the same as those of other parts of the honeycomb core, and then the overall uniformity of the spliced honeycomb plate is guaranteed; and the whole spliced honeycomb plate is closer to the performance of the whole honeycomb plate.

Description

technical field [0001] The present application relates to the technical field of composite panel production, in particular to a spliced ​​honeycomb panel and a production method for splicing the honeycomb panel. Background technique [0002] At present, honeycomb sandwich composite materials have a large number of applications in the field of vehicle, airborne, shipboard structures and electronics. The honeycomb sandwich structure has the advantages of high strength, light weight, and strong designability of electrical thickness. Its dielectric properties can be changed to further expand the application range of the honeycomb in the field of electrical structural functional parts. Due to the limitation of the size of the honeycomb sandwich composite material, splicing is often required. Under normal circumstances, splicing is carried out with foamed rubber film. The splicing of foamed rubber film is characterized by excess strength and stiffness at the splicing position, an...
