Abstract
The invention discloses a bonding method of a honeycomb sandwich structure of a micro-perforated panel. The method is characterized by comprising following steps of: subjecting a bonding surface of the micro-perforated panel before bonding to surface treatment, such as anodizing with phosphoric acid or anodizing with chromic acid; coating the bonding surface (the right surface of the panel) with a primer, blowing out the primer in the micropores by using air flow from the back side of the panel, and subjecting the primer used for improving corrosion resistance of bonding parts to curing treatment; paving medium-temperature curing adhesive film or high-temperature curing adhesive film which are matched with the panel and a honeycomb core on the bonding surface and putting into an oven and heating the adhesive film to a fusion state; taking out the panel, blowing out the adhesive film in the micropores by using air flow from the back side of the panel so as to avoid that a large number of the micropores on the panel are blocked by the adhesive film after curing processes; and pasting the honeycomb core on the panel with the adhesive film, putting into an autoclave and curing. The bonding method can solve a micropore blocking problem of the micro-perforated panel during a honeycomb bonding process, and can prepare a micro-perforated panel soundproofing liner structure which belongs to structural functional parts. According to different perforating parameters and honeycomb parameters, noise in a target frequency band can be reduced effectively.
Description
Technical field
The invention belongs to nacelle of airplane noise elimination structure design field, be specifically related to a kind of adhering method of microperforated panel honeycomb sandwich construction.
Background technology
The adhering method of general honeycomb is directly by honeycomb panel brush primer, glued membrane, then with bonding honeycomb core and put into autoclave and be cured.This kind of method step is simple, easy to operate, and process certification is mature technology, has been widely used in the splicing of general honeycomb.But in the curing process of glued membrane, if honeycomb panel is microperforated panel, in solidification process, the glued membrane of paving on panel can be by the micropore stopping up in a large number on microperforated panel.Therefore, the adhering method of general honeycomb be not suitable for the splicing of micropunch panel honeycomb sandwich construction.
Summary of the invention
The object of the invention is: the present invention is intended to solve the problem of blockage of the micro orifice on honeycomb adhesive termination process middle punch plate.
Technical scheme of the present invention is: a kind of adhering method of microperforated panel honeycomb sandwich construction, it is characterized in that, and comprise the steps:
The first, before glueing joint, perforated panel splicing face is carried out to surface treatment, as phosphoric acid or chromic acid anodizing;
The second, at splicing face (panel front) brush primer, and after the primer from back side of panel blowing micropore, then above-mentioned primer is cured to processing with air-flow, primer is for improving the corrosion resistance of bonded part;
The 3rd, the intermediate temperature setting glued membrane mating with panel and honeycomb core in above-mentioned splicing face paving or hot setting glued membrane, put into baking oven glued membrane heated to molten condition;
The 4th, take out panel, and from back side of panel, blow down the glued membrane micropore with air-flow, in order to avoid the micropore solidifying on rear board is stopped up in a large number by glued membrane;
The 5th, on the panel with glued membrane, paste honeycomb core, put into autoclave and be cured.
The method that in described second step, primer is cured to processing is that oven dry or room temperature are dried.
The invention has the beneficial effects as follows: compare with existing honeycomb adhesive connection technology, the method can solve the problem of blockage of the micro orifice on honeycomb adhesive termination process middle punch plate, prepare microperforated panel acoustical liner structure, this structure belongs to structure function part, according to the difference of perforation parameter and honeycomb parameter, can be so that the noise of target frequency bands effectively reduces.

The 3rd, the intermediate temperature setting glued membrane mating with panel and honeycomb core in above-mentioned splicing face paving or hot setting glued membrane, put into baking oven glued membrane heated to molten condition;
The 4th, take out panel, and from back side of panel, blow down the glued membrane micropore with air-flow, in order to avoid the micropore solidifying on rear board is stopped up in a large number by glued membrane;
The 5th, on the panel with glued membrane, paste honeycomb core, put into autoclave and be cured.
The method that in described second step, primer is cured to processing is that oven dry or room temperature are dried.
According to above adhering method, successfully prepared at present microperforated panel honeycomb sandwich construction, and be applied to aircraft air intake duct.See Fig. 2.
By above application, proved practicality and the operability of the method.Than traditional sheet metal structural, microperforated panel honeycomb sandwich construction has higher strength and stiffness, and has good sqouynd absorption lowering noise effect.
