Abstract
The present invention relates to a kind of connection methods of paper honeycomb sandwich structure, it is characterized by: designing initial stage in honeycomb sandwich structure, according to design requirement in the pre-buried glass reinforced plastic inserts (3) of honeycomb sandwich structure join domain (4), and by glass reinforced plastic inserts (3) and paper honeycomb (4), carbon fiber face sheets (1) co-curing, then on the embedment region of glass reinforced plastic inserts (3), fastener connection through-hole is drilled by design requirement, realizes the fastener connection in cellular sandwich region.The present invention can compare to be connected reliably simultaneously in guarantee cell, is not generated destruction to honeycomb, is improved the structure efficiency of honeycomb sandwich structure, reduce construction weight, the rigidity advantage for having played honeycomb sandwich structure of maximum possible.
Description
Technical field
The present invention is suitable for field of structural design, is particularly suitable for the connection of Composite Sandwich structure.
Background technique
Current honeycomb sandwich structure is all to be attached by the laminate at edge, honeycomb is in bonding pad in connection
Just end before, so that the rigidity of cellular board mutates, is unfavorable for carrying, but Joining Technology is relatively easy.
Summary of the invention
Goal of the invention: a kind of connection method of paper honeycomb sandwich structure is proposed.
Technical solution: a kind of connection method of paper honeycomb sandwich structure designs initial stage in honeycomb sandwich structure, according to design
It is required that in the pre-buried glass reinforced plastic inserts 3 of honeycomb sandwich structure join domain 4, and by glass reinforced plastic inserts 3 and paper honeycomb 4, carbon fiber
1 co-curing of panel is tieed up, then on the embedment region of glass reinforced plastic inserts 3, drills fastener connection through-hole by design requirement, it is real
The fastener connection in existing cellular sandwich region.
Preferably, the diameter of glass reinforced plastic inserts 3 should be with the diameter matches of fastener.3 diameters of glass reinforced plastic inserts/fastening
Part diameter is 4/1.The height of glass reinforced plastic inserts 3 is less than the height of paper honeycomb 4.The roughness of 3 outer surface of glass reinforced plastic inserts
Greater than R6.4.
Preferably, when embedded hole is produced on paper honeycomb 4, paper honeycomb 4 is in reasonable Pre strained state, the glass reinforced plastic edge produced
The aperture of 3 embedded hole of inserts is consistent with the outer diameter of glass reinforced plastic inserts 3.
Preferably, it when embedded in glass steel inserts 3, is first uniformly smeared and honeycomb sandwich structure solidification temperature phase in its appearance
Same structural adhesive；After solidification on carbon fiber face sheets 1 with banister bruss mark the embedment region of glass reinforced plastic inserts 3 so as to
It is subsequent to drill fastener connection through-hole.
The advantages of invention: the present invention can compare to be connected reliably simultaneously in guarantee cell, does not generate destruction to honeycomb,
The structure efficiency for improving honeycomb sandwich structure, reduce construction weight, and maximum possible has played honeycomb sandwich structure
Rigidity advantage.
Detailed description of the invention
Fig. 1 is structure of the invention cross-sectional view
Specific embodiment
As shown in Figure 1, a kind of connection method of paper honeycomb sandwich structure, initial stage is designed in honeycomb sandwich structure, according to setting
Meter is required in the pre-buried glass reinforced plastic inserts 3 of honeycomb sandwich structure join domain 4, and by glass reinforced plastic inserts 3 and paper honeycomb 4, carbon
1 co-curing of fiber panel drills fastener connection through-hole by design requirement then on the embedment region of glass reinforced plastic inserts 3,
Realize the fastener connection in cellular sandwich region.
The diameter of glass reinforced plastic inserts 3 should be with the diameter matches of fastener.3 diameters of glass reinforced plastic inserts/diameter fastener
It is 4/1.The height of glass reinforced plastic inserts 3 is less than the height of paper honeycomb 4.The roughness of 3 outer surface of glass reinforced plastic inserts is greater than
R6.4。
When embedded hole is produced on paper honeycomb 4, paper honeycomb 4 is in reasonable Pre strained state, and the glass reinforced plastic inserts 3 produced is pre-
The aperture of buried via hole is consistent with the outer diameter of glass reinforced plastic inserts 3.When embedded in glass steel inserts 3, first uniformly smears in its appearance and
The identical structural adhesive of honeycomb sandwich structure solidification temperature；Glass is marked with banister bruss on carbon fiber face sheets 1 after solidification
The embedment region of steel inserts 3 drills fastener connection through-hole so as to subsequent.
The present invention solves honeycomb by devising a harness fastener connection method to carbon fiber aramid paper honeycomb sandwich structure
Sandwich structure leads to the problem of honeycomb lattice be collapsed, routed when fastener connects.Rigidity, intensity to honeycomb sandwich structure simultaneously
It does not produce bigger effect, significant change does not occur for weight.So that aramid paper honeycomb sandwich structure is in aviation field using more
Extensively.
