Abstract
The invention discloses the metal honeycomb core composite single plate structure of a kind of antistatic, this structure is by the method connecting wire between composite sheetmetal embedded part and aluminum honeycomb, all metal embedded part wires are connected together, realize the veneer any two points resistance value antistatic target less than 10 Ω, solve the Insulation Problems between metal honeycomb core composite veneer local and integral insulation, particularly metal embedded part.It is an advantage of the current invention that to it solve the local of metal honeycomb core composite panel and integral insulation problem, alleviate satellite surface and internal electrostatic defending pressure.
Description
Technical field:
The present invention relates to the metal honeycomb core composite single plate structure of a kind of antistatic, be specifically related to one
The carbon fiber skin aluminium honeycomb core composite single plate structure of antistatic.
Background technology:
Geostationary orbit satellite, particularly geostationary orbit three-axle steady platform satellite, surface and inside
It is faced with serious charging, discharges and relevant electromagnetic interference problem.When the insulator of inside satellite is subject to
When the directly effect of solar plasma ray is charged above the electric discharge marginal value of this insulant, just
Static discharge phenomenon can occur.This electric discharge phenomena the lighter can form interference to the Sensitive Apparatus of surrounding, leads
Cause equipment operation irregularity；Severe one then can damage low-voltage device and Sensitive Apparatus, directly threatens equipment and satellite
Operation safety.
Measured data shows, the turn-on effect of composite structure surface and inside is generally not reaching to expection
Requirement.Between embedded part and embedded part there is the biggest uncertainty in conducting state, and maximum resistance can reach
More than 100M Ω.Between any two embedded part that this and satellite antistatic design specification require, resistance value is less than 10
The index of Ω is far apart.
Summary of the invention:
The present invention proposes the metal honeycomb core composite single plate structure of a kind of antistatic.Solve composite wood
Material body structure surface and the problem of internal antistatic
As shown in Figure 1, wherein conduct electricity has the structure of composite cellular board: eyelid covering 1, metal beehive
3, metal embedded part 5, nonconducting have: foamed glue 4, glued membrane 2, metal embedded part oxide-film 6.Composite wood
Between flitch embedded part and embedded part non-conductive be because each brood lac by these conductor insulations.According to practical experience,
Metal beehive 3 and eyelid covering 1 are conductings, because contact area is big, sting as long as metal beehive 3 has at one
Broken glued membrane 2 is connected will turn on eyelid covering 1.And the on-state rate ratio of metal embedded part 5 is relatively low, it is because
Having foamed glue 4 around metal embedded part 5, upper and lower surface has glued membrane 2.In sum, as long as by metal embedded part
5 turn on metal beehive 3, it is possible to realize the conducting between metal embedded part 5 and eyelid covering 1 and remaining embedded part,
Also it is achieved that imposite turns on.According to this Analysis on Mechanism, it is only necessary to utilize plain conductor 8 to be buried by metal
Part 5 and neighbouring metal beehive 3 turn on, it is possible to realize imposite conducting.
The present invention between metal embedded part 5 and neighbouring metal beehive 3 by remove metal embedded part oxide-film
6, increase wire 8 and realize conducting, wire 8 is the common metal wire removing insulated hull；Metal beehive
3 pass through eyelid covering 1 mutual conduction, thus realize mutual conduction between any embedded part, reach veneer any two
Embedded part resistance value is less than 10 Ω.
Beneficial effect: it is an advantage of the current invention that it solves the local of metal honeycomb core composite panel and whole
Body Insulation Problems, alleviates satellite surface and internal electrostatic defending pressure.
Accompanying drawing illustrates:
Fig. 1 is composite honeycomb plate structure: wherein: 1, eyelid covering；2, glued membrane；3, metal beehive；4、
Foamed glue；5, metal embedded part；6, metal embedded part oxide-film.
Fig. 2 is to punch on embedded part and twine wire: wherein: 7, wire；8, conducting resinl.
Fig. 3 is that thin-walled embedded part is directly wound around wire.
Detailed description of the invention
1. wire prepares: select the common metal core wire removing insulating barrier.
2. metal embedded part conduction is implemented
Metal embedded part connects wire.Type of attachment has 2 kinds:
The first, directly spile on embedded part (can be sized according to diameter of wire), by wire from little
Passing in hole, winding is tightened, and conducting resinl on point at aperture and kinking, as shown in Figure 2.
The second, for the thin-walled embedded part not having space to punch, uses the mode being directly wound around wire, notes
Polish off the oxide-film being wound around position, as shown in Figure 3.
The embedded part completing conduction enforcement is conducted test, and embedded part and wire termination should be on shape
State.
3. veneer conduction is implemented:
The embedded part implemented is put into cellular board by normal procedure, cuts the honeycomb wall near wire, by embedded part
Upper reserved wire sticks in the honeycomb wall of incision, and the upper conducting resinl of point is fixed.
Check after enforcement whether all embedded parts and honeycomb turn on (resistance value is less than 10 ohm).If all
It is qualified to check, and continues to carry out according to cellular board normal process.Otherwise repair, until all meeting conducting
Condition.
The casing of certain model remote sensing instrument carbon fiber skin aluminium honeycomb core composite panel composition is carried out
Test, completes conduction process implementing by the art of this patent, and after veneer development completes, conduction checks that result is as follows:
Altogether prepare veneer 8 pieces, measure at embedded part 658, wherein within 10 Ω at 602 (91.5%), 10～100
At Ω 41 (6.2%), at 9 be not turned on (1.3%).Through later stage conductive processing, 100% can be reached
Conducting.
