Further relate to the preparation method of a kind of submarine pressure hull.
Background technology
Submarine is one of important naval vessels of navy fight, and it can move on maneuverability ground under water, is used for attacking the other side
Battleship on the water surface and the submarine in water, it is also possible to attacking the target of military importance of land, it can also undertake cloth if desired
Thunder, scouting and personnel carrier and the important task of important military materials.Submarine has the most disguised and surprise attack ability, at water
In can for a long time, the lasting navigation of distance.Submarine Structure has mono-hull, Double-casing, single double mixing housings three kinds, mono-hull
For pressure hull, Double-casing is for also to have one layer of non-pressure hull outside pressure hull.Along with constantly sending out of sonar contact technology
Exhibition improves constantly with detectivity, and the disguise of the submarine that and strategic arms conventional as naval are equipped receives serious choosing
War.Mono-hull submarine is compared with Double-casing submarine, and when pressure-resistant cabin volume is identical, wetted surface area is less, thus sound reflecting area is little,
Under same tonnage, pressure-resistant cabin space is bigger, is beneficial to lay the sonar of bulky complex, noise reducing apparatus, and disguise is higher, becomes
Main flow Submarine Structure.
At present, submarine hull typically uses the high strength steels such as HY-80, HY-100 to make, but the manufacture process energy consumption of steel
Height, can discharge substantial amounts of harmful gas, causes serious atmospheric pollution.And the quality of steel own is big, limits it and travel speed
Degree.

Midships section end retains the enhancement layer of the first width only wound section thickness, prepares midship stern enhancement layer；
Prepared by midship stern external protection coating: the bamboo fibre non-woven fabrics being impregnated with by the epoxy vinyl ester resin being formulated is wound around
On midship stern enhancement layer, if winding dried layer is to external protection coating design thickness, in midships section end the first width, or not is not wound around outer protection
Layer, prepares midship stern external protection coating；
Solidification: to being wound with midship stern inner liner, midship stern enhancement layer and midship stern external protection coating the most successively
Submarine midship stern mould is heating and curing, after having solidified, and the demoulding, midship stern inner liner, midship stern enhancement layer and midship stern
External protection coating is compound becomes midship stern shell body；
Prepare midship bow shell body:
Submarine midship bow mould use the mode identical with preparing midship stern shell body be sequentially prepared midship bow liner
Layer, midship bow enhancement layer and midship bow external protection coating, retain the enhancing of the first width only wound section thickness equally at midships section end
Layer and be not wound around external protection coating, anti-to being wound with the most successively outside midship bow inner liner, midship bow enhancement layer and midship bow
The submarine midship bow mould of sheath is heating and curing, after having solidified, the demoulding, midship bow inner liner, midship bow enhancement layer and
Midship bow external protection coating is compound becomes midship bow shell body；
Connect steel skeleton: on the inner surface of the midship stern shell body prepared and midship bow shell body, coat epoxy respectively
Resin, the most bonding steel skeleton, after heated solidification, steel skeleton is fixed on midship stern shell body and the interior table of midship bow shell body
On face；
Midship bow shell body is connected with midship stern shell body: docked with midship stern shell body by midship bow shell body, docking
Place's packing ring epoxy resins, within this retains dock mutually two sections of first width, common winding is wrapped completely by amino resins afterwards
The thin bamboo strips used for weaving sheet covered, to enhancement layer design thickness, is wound around the bamboo fibre nonwoven that the epoxy vinyl ester resin being formulated is impregnated with afterwards
Cloth, to the design thickness of external protection coating, through being heating and curing, completes the preparation of shell body；
Above step is all carried out under conditions of ambient humidity is less than 40%RH.

The design thickness of external protection coating, through being heating and curing, completes the preparation of shell body；
Above step is all carried out under conditions of ambient humidity is less than 40%RH.
5. the preparation method of submarine pressure hull as claimed in claim 4, it is characterised in that described only winding inner liner and portion
Divide the first width segments of the enhancement layer of thickness and there is shape between complete inner liner, enhancement layer and the remainder of external protection coating
Becoming faceted pebble, described faceted pebble is hackly inclined plane.
6. the preparation method of submarine pressure hull as claimed in claim 4, it is characterised in that described curing mode is from mould
Inside outwards and is heating and curing the most jointly from mold exterior, and is higher than from mould from the solidification rate that mould inside is outside
The solidification rate that portion is inside；Start just to carry out continuous heating solidification from preparing inner liner, until having prepared external protection coating and having made
External protection coating has solidified.
7. the preparation method of submarine pressure hull as claimed in claim 4, it is characterised in that described midship bow shell body and midship
Stern shell body junction inner surface is bonded with multi-storey up-down and translation and reinforces.
8. the preparation method of submarine pressure hull as claimed in claim 4, it is characterised in that described thin bamboo strips used for weaving sheet width is 5mm-
20mm, thickness is 0.3mm-2mm.
9. the preparation method of submarine pressure hull as claimed in claim 4, it is characterised in that described amino resins gluing agent bag
Include amino resins 100 mass fraction, biologic packing material 15-30 mass fraction, nano material 1-3 mass fraction.
10. the preparation method of submarine pressure hull as claimed in claim 4, it is characterised in that described epoxy vinyl ester tree
Fat adhesive includes epoxy vinyl ester resin 100 mass fraction, toughener 3-5 mass fraction, diluent 12-15 mass parts
Number, carbon nano-fiber 1-3 mass fraction.
