Embodiment
A kind of low-cost production device of thin-walled composite material skin structural member, such as Fig. 1, including resin storage tank 1, injecting glue pipeline 2, vacuum bag film 3, sealing coat 9, sealing joint strip 4, mould 5, exhaust pipe, surge tank 7, vacuum equipment 8, vacuum bag film 3 is sealed by sealing joint strip 4 with mould 5, vacuum bag film 3 and mould 5 are formed with sealing chamber, annular seal space indoor are provided with the reinforcement 10 of some layers of thin-walled composite material skin, some sealing coats 9, release cloth 1, permeable medium 12, sealing coat 9 is located between adjacent thin-walled composite material skin, the common top of thin-walled composite material skin is sequentially provided with release cloth 1, permeable medium 12, the two ends of injecting glue pipeline 2 are connected with resin storage tank 1 and vacuum bag film 3 respectively, one end connection vacuum bag film 3 of exhaust pipe 1, the other end of exhaust pipe 1 is connected to surge tank 7, surge tank 7 connects vacuum equipment 8 again through exhaust pipe 2 13。
Such as Fig. 2, sealing coat 9 is to include release cloth 2 92 and isolating membrane 91, and isolating membrane 91 is clipped in the middle by two-layer release cloth 2 92。
The length of permeable medium 12 is identical with the length of the reinforcement 10 of thin-walled composite material skin, and the width of permeable medium 12 is compared with the short 3cm ~ 10cm of width of the reinforcement 10 of thin-walled composite material skin。
A kind of low cost production thereof of thin-walled composite material skin structural member, by the cleaning cleaning of mould 5 surface blot, coat releasing agent, paving covers the reinforcement 10 of thin-walled composite material skin, repaves and covers sealing coat 9, and then second layer paving covers the reinforcement 10 of thin-walled composite material skin, repave and cover sealing coat 9, according to this order, the like, until n-th layer thin-walled composite material skin paving has been covered。
After treating that all of thin-walled composite material skin structural member reinforcement 10 paving has been covered, paving covers release cloth 1 and permeable medium 12 successively, encapsulation, connection glue injection pipeline 2 and exhaust pipe 1, exhaust pipe 2 13, the vacuum of detection vacuum system, perfusion resin, after resin infusion operation completes, need to seal gum-injecting port, prevent in the curing process, vacuum system gas leakage causes scrapping of product, sets cure parameter and carries out the solidification of product, and the last demoulding obtains thin-walled composite material skin structural member。
The low cost production thereof of this kind of thin-walled composite material skin structural member, efficiently, low cost, one-time process enforcement and plastic N block thin-walled composite material skin structural member, separated by sealing coat 9 between every two-layer thin-walled composite material skin structural member, so that two-layer thin-walled composite material skin structural member can separate after solidification well, solve release problems。Sealing coat 9 is made up of two-layer release cloth and one layer of isolating membrane 91, isolating membrane 91 between two-layer release cloth, the existence of isolating membrane 91, be unlikely to when the demoulding by composite material skin damage。
As in figure 2 it is shown, the paving of sealing coat 9 covers order for release cloth 2 92, isolating membrane 91, release cloth 2 92。When paving covers ground floor release cloth 2 92, glue spraying is used to be fixed in the edge of thin-walled composite material skin, it is prevented that it slides, and is fixed on ground floor release cloth 2 92 by use adhesive tape or glue spraying by isolating membrane 91, and last layer of release cloth 2 92 also needs to fix。The paving of release cloth 2 92 and isolating membrane 91 is covered, it is necessary to assure it is completely smooth at thin-walled composite material skin structural member surface。
The low cost production thereof of this kind of thin-walled composite material skin structural member, improves the production efficiency of thin-walled composite material skin structural member, reduces cost。This process economics, efficiently it is shaped to the improvement of vacuum introducing technology, compared with traditional vacuum introducing technology, one-time process enforcement and plastic N block thin-walled composite material skin structural member, separated by sealing coat 9 between every two-layer thin-walled composite material skin structural member, so that two-layer thin-walled composite material skin structural member can separate after solidification well, solve release problems。Temperature according to injecting glue environment and the viscosity of resin, determine that one-time process implements the quantity of plastic thin-walled composite material skin structural member, considering, it is best that one-time process implements 3 ~ 5 pieces of thin-walled composite material skin structural members of molding, and the thickness of thin-walled composite material skin structural member is 1 ~ 2mm。
This device and each process implementing of technique and plastic N block thin-walled composite material skin structural member, the main materials such as production efficiency improves N times, and (N-2)/(N-1) ~ (N-2)/N saved by auxiliary material, labour cost saving (N-2)/N, resin also can be saved many。While improving thin-walled composite material skin structural member production efficiency, save manufacturing cost, increase the application advantage of composite。
