Abstract
The present invention discloses a kind of method for enhancing honeycomb core, step are as follows: milling goes out to install the hole of carbon pipe on honeycomb core；Stripping laying is smooth, glue film side is served as a contrast and removes rear laying on stripping；By honeycomb core laying on glue film；One layer of foamed glue is wrapped up in carbon pipe surface；Carbon pipe is installed in honeycomb core bore；Honeycomb core encapsulation is solidified；Honeycomb core is processed in milling.Carbon pipe wraps up in foamed glue front surface and carries out blast processing, cleaning, drying.The stripping of cutting is more bigger than glue film, about 5-10mm.Carbon pipe is installed in honeycomb core bore using tooling.The present invention enhances honeycomb core in such a way that carbon pipe is embedded in honeycomb core, it will be bonded between carbon pipe and honeycomb core using foamed glue, guarantee the relative position of honeycomb core and carbon pipe using the location hole in tooling, connector can be attached with carbon pipe when assembly, solves the connectivity problem of honeycomb core region and metal joint, carbon pipe is light-weight and hollow, effectively alleviates the weight of part.
Description
Technical field
The present invention relates to the methods of enhancing honeycomb core part, more particularly to enhance honeycomb core in composite material manufacturing process
Method.
Background technique
It is the connection in subsequent assembling process with connector to honeycomb sandwich composite part, needs honeycomb core is corresponding
Region enhancing, common scheme are in the subsequent honeycomb core band of position for needing to connect using casting glue filling and cured form
Reach honeycomb core enhancing, it is ensured that can effectively connect with connector in the region in subsequent assembly, to guarantee effectively connection, fill out
It fills region and needs bigger than join domain area, cause honeycomb core pts wt to increase excessive.Casting glue also needs to guarantee when filling
Completely, no air entrains into for filling region filling, and in actual mechanical process, because the viscosity of casting glue is big, honeycomb core thickness mistake
When big, operation is extremely difficult, and easily entrains into air, filling occurs not exclusively, connection loosening when easily leading to assembly.
Summary of the invention
To solve the problems, such as after connecting and fill when enhancing honeycomb core operating difficulties and assembly with casting glue in the prior art
Honeycomb core increase excessive unnecessary weight, the present invention provides the methods using carbon pipe enhancing honeycomb core.
A kind of method for enhancing honeycomb core of the present invention, includes the following steps:
1) milling goes out to install the hole of carbon pipe on honeycomb core；
2) carbon pipe is chosen, carbon pipe is cut into and the consistent length of honeycomb core height；
3) glue film side is served as a contrast and removes rear laying on stripping；
4) stripping laying is smooth, by honeycomb core laying on glue film；
5) one layer of foamed glue is wrapped up in carbon pipe surface；
6) carbon pipe is installed in honeycomb core bore；
7) it is packaged and vacuumizes in one layer of isolation film of honeycomb core surface mount；
8) solidify；
9) milling processes required honeycomb core height.
In the step 2, it is sealed for use after carbon pipe surface is carried out blast processing, cleaning, drying.
In the step 3), the stripping of cutting is 5-10mm more bigger than glue film,
In the step 6), carbon pipe is installed in honeycomb core bore using tooling, include in tooling position carbon pipe pin and
Block guarantees the relative position of honeycomb core and carbon pipe by the location hole in tooling.
In the step 5), solvent cleans carbon pipe before carbon pipe surface wraps up in foamed glue.
The present invention has a following good effect compared with the prior art, and the present invention is in such a way that carbon pipe is embedded in honeycomb core pair
Honeycomb core is enhanced, and will be bonded between carbon pipe and honeycomb core using foamed glue, guarantees bee using the location hole in tooling
The relative position of nest core and carbon pipe, connector can be attached with carbon pipe when assembly, efficiently solve honeycomb core region and metal
The connectivity problem of connector effectively alleviates the weight of part simultaneously as carbon pipe is light-weight and is hollow structure.
Specific embodiment
The invention will be further described below
