Splicing device and method for large-size paper honeycomb parts

Abstract

The invention discloses a splicing device and method for large-size paper honeycomb parts. The splicing device comprises a splicing forming tool, wherein honeycomb interlayers to be spliced are packaged on the splicing forming tool; polystyrene foam is laid and pasted at the splicing seams between the honeycomb interlayers to be spliced; a first isolation layer is laid between the honeycomb interlayers and the splicing forming tool, and a second isolation layer is laid on the honeycomb interlayers; a plurality of pressing plates are placed on the second isolation layer; and strippable cloth islaid on the splicing seams, a third isolation layer is laid on the strippable cloth, and gaskets are placed on the third isolation layer. The splicing method comprises the steps that honeycomb core materials and the like are packaged on the splicing forming tool according to requirements to be cured; the pressing plates fix honeycombs on the two sides of the polystyrene foam to prevent the honeycombs from sliding, and the width of the splicing seams caused by thermal expansion of the polystyrene foam is reduced; and the gaskets are placed on the splicing seams to evenly transmit pressure. Thesplicing method is simple and easy to control, and the quality and the percent of pass of the spliced honeycombs can be greatly improved.

Description

technical field [0001] The invention relates to a splicing device and method for large-size paper honeycomb parts. Background technique [0002] The honeycomb sandwich structure composite material part is composed of two high-strength upper and lower composite panels sandwiching a layer of honeycomb core, because of its light weight, high bending strength and rigidity, strong resistance to instability, fatigue aging resistance, sound absorption , Sound insulation and heat insulation performance are good. At present, it has been widely used, especially in the field of aerospace, honeycomb sandwich structure composite materials have been widely used in aircraft structures, such as wings, fuselage, empennage, radome and floor, interior decoration, etc. Become one of the indispensable structural materials in this field. [0003] When the required size of the internal core material of the composite sandwich structure is larger than that of the raw material, foaming glue is ofte...
