Abstract
The invention belongs to Composites Molding Techniques, relate to a kind of improvement to large-sized composite tubular honeycomb sandwich construction preparation method. The present invention increases a set of laying frock (this laying frock profile is shape in product), changes laying flow process and reaches the object that realizes laying, and laying step is as follows: paste vacuum bag; Paved inside panel, honeycomb, exterior skin; Laying frock is put into shaping mould; Vacuum bag in laying frock is oppositely made on shaping mould and vacuumized; Laying frock is taken out in shaping mould; Original vacuum bag is removed, again made vacuum bag. The present invention is by increasing laying frock, will on shaping mould, be difficult to the laying that realizes, transfers to and in laying frock, carries out laying, thereby solved the problem that is difficult to realize laying in large scale, honeycomb sandwich construction traditional operation.
Description
Technical field
The invention belongs to Composites Molding Techniques, relate to a kind of to large-sized composite tubularHoneycomb sandwich construction preparation method's improvement.
Background technology
The manufacture of existing honeycomb sandwich construction, all taking theoretical profile as forming frock profile, to cylinderThe honeycomb sandwich construction product of shape structure, theoretical profile is outer surface, so forming frock is tubularDie, the roofing that its inner surface is product, traditional laying method is: first on forming frockPaved exterior skin, repaves honeycomb processed, inside panel and finally makes vacuum bag. This tradition forming method existsShortcoming in large scale tubular honeycomb sandwich construction is: due to narrow space, and when structure is longer, peopleMember cannot enter shaping mould inner side, will be difficult to carry out laying.
Summary of the invention
The object of the invention is to propose the laying of a kind of adaptation and large scale, tubular honeycomb sandwich constructionMethod.
Technical scheme of the present invention is:
(1) prepare laying frock, the profile of laying frock is corresponding with shape in product, and laying frock isPunch structure;
(2) paste normal-temperature vacuum bag, in laying frock, paste normal-temperature vacuum with normal-temperature vacuum filmBag also vacuumizes all the time, vacuum 0.06～0.09Mpa, and vacuum bag is more than product circumferential direction staysAmount 100～150mm, vacuum bag is at product length direction two ends made allowance 200～250mm, and general is normalTemperature vacuum bag sticks in laying frock by adhesive tape;
(3) paved inside panel: 2～3 layers of inside panel laying of every paving on normal-temperature vacuum bag, carry outOnce vacuumize compacting, vacuum 0.06～0.09Mpa, last one deck laying is carried out once againVacuumize compacting, vacuum 0.06～0.09Mpa;
(4) place honeycomb;
(5) paved exterior skin: the paved one deck exterior skin on honeycomb, vacuumizes compacting, vacuumDegree 0.06～0.09Mpa, then, 2～3 layers of exterior skin laying of every paving, once vacuumize pressureReal, vacuum 0.06～0.09Mpa, last one deck laying once vacuumizes compacting again,Vacuum 0.06～0.09Mpa;
(6) preform that above-mentioned (1)～prepared by (5) is put into shaping mould, matched moulds;
(7) adhesive tape of the normal-temperature vacuum bag in laying frock is taken off, by normal-temperature vacuum bag adhesive tapeOppositely stick on shaping mould and vacuumize, vacuum 0.06～0.09Mpa;
(8) laying frock is taken out in shaping mould;
(9) normal-temperature vacuum bag is removed, again made high temperature resistant vacuum bag, enter stove and solidify.
Described shaping mould is upper and lower involutory die body, when moulding, first laying frock is put into mouldingIn the lower mold body of mould, then the upper die body that closes.
The advantage that the present invention has and beneficial effect, the present invention is by increasing laying frock and improving pavingThe means of layer order, have reduced the laying difficulty of product, have solved narrow space, and personnel cannot enterEnter shaping mould inner side, be difficult to carry out the difficult point of laying, and improve the operability of laying and ensure layingQuality.
Detailed description of the invention
Below the present invention is described in further details. Large scale tubular honeycomb sandwich construction laying sideMethod, is characterized in that, (this laying frock profile is shape in product, knot to increase a set of laying frockStructure is punch, can make operator carry out easily laying in the outside of frock), change laying order and reachTo the object that realizes laying. Concrete step is as follows:
1, paste vacuum bag: in laying frock, only have normal-temperature vacuum film to paste normal-temperature vacuum bag alsoAll the time vacuumize vacuum 0.06～0.09Mpa; To ensure the laminating of vacuum bag and laying frock,There is no large fold. Vacuum bag should reserve necessarily in product circumferential direction and product length direction two endsSurplus; Vacuum bag is at product circumferential direction made allowance 100～150mm, and vacuum bag is at product lengthDirection two ends made allowance 200～250mm,
2, paved inside panel: 2～3 layers of inside panel laying of every paving on vacuum bag, once take outVacuum debulk, last one deck laying will once vacuumize compacting, vacuum 0.06～
0.09Mpa；
3, place honeycomb;
4, paved exterior skin: the ground floor on honeycomb vacuumizes compacting, vacuum 0.06～After 0.09Mpa, 2～3 layers of exterior skin laying of every paving, once vacuumize compacting, last one deckLaying once vacuumizes compacting, vacuum 0.06～0.09Mpa;
5, laying frock is put into shaping mould: for guarantee laying frock can be put into moulding smoothlyIn mould, this shaping mould need to carry out piecemeal, generally can be divided into upper and lower involutory die body, first by layingFrock is put into the lower mold body of shaping mould, then the upper die body that closes;
6, the normal-temperature vacuum bag in laying frock is oppositely made on shaping mould and vacuumized;
7, laying frock is taken out in shaping mould: generally produce haulage gear in laying frock,Adopt trailer that laying frock is extracted from shaping mould;
8, original normal-temperature vacuum bag is removed, (this place is for normal true again to make high temperature resistant vacuum bagThe preparation of empty bag, contains barrier film, ventilative station, vacuum film), enter stove and solidify.
The principle that the present invention realizes laying is: by increasing laying frock, and will be difficult on shaping mouldWith the laying realizing, transfer to and in laying frock, carry out laying, thereby solved large scale, honeycombIn sandwich traditional operation, be difficult to realize the problem of laying.
