Bonding pad strengthening course reinforcing material glass fibre or carbon fibre fabric minimum widith are more than or equal to 30mm in the present invention,
Then 5mm-15mm is successively increased, fabric maximum width must be less than between upper and lower panel highly or bonding pad is away from structural edge width 2
Minimum value again, reinforcement layer thickness is 3mm-5mm.
The present invention is directed to frame-type composite material raft frame or base construction form, and analysis decomposition, its point are carried out to its structure
It is as follows to solve principle：（1）Partitioned organization is as far as possible few, to reduce connection quantity, improves the security of composite material raft frame or pedestal；
（2）Each composite structure decomposed should be easy to shaping, to improve composite material Forming Quality.
The present invention is described in further detail with reference to following embodiments；But following embodiments are only illustration, this hair
It is bright to be not limited to these embodiments.
Step 1: the STRUCTURE DECOMPOSITION of raft frame or pedestal
Decomposed according to the overall structure form of raft frame or pedestal, be decomposed into top panel, lower panel and transverse and longitudinal floor, its
In, transverse and longitudinal floor includes multiple horizontal gussets and longitudinal gusset, between top panel and transverse and longitudinal floor and lower panel and transverse and longitudinal rib
Connection mode between plate is "T"-shaped grafting, and the connection mode between horizontal gusset and longitudinal gusset is " ten " shape grafting,
Decomposing scheme is finally obtained, decomposing scheme includes the number and size of top panel, lower panel and transverse and longitudinal floor；
By taking the frame of composite material raft shown in Fig. 5-8 as an example, length 2500mm, width 2200mm, total height 240mm, cross rib
Plate 7, longitudinal floor 5.
Each panel forming size of table 1
Step 2: the shaping of composite material partitioned organization, the demoulding
The decomposing scheme obtained according to step 1 makes the mould to match, and the shaping of each piecemeal, base are carried out using mould
Body material and curing agent are molded, and forming method is vacuum assisted resin injection moulding process, die press technology for forming or resin
Any of Transfer molding technique, it is also compound to improve added with damping layer material when composite material partitioned organization is molded
The damping capacity of material raft frame, is demoulded after curing, obtains each piecemeal molding structure, spare；
Fabric is using biaxially fabric E-LT450.According to molding plate size carry out respective fiber fabric and
The cutting of damping layer.The fabric cut is put into baking oven and carries out drying and processing, drying temperature is 100 DEG C ± 2 DEG C, is dried
The dry time is 120 ± 5min.
Resin is cured as RIMH137, matching as 100 using the epoxy resin RIM135 of Germany Han Sen companies:30.
The present embodiment panel construction uses vacuum assistant resin infused, and fabric and damping layer are carried out according to Lay up design
Be plated in, be plated in mode and orthogonal be plated in for 0 °/90 °.Release cloth, flow-guiding cloth, injected rubber hose and true are carried out according to vacuum assisted process
The laying of blank pipe, vacuum sealing is carried out using double-ply bag film.The leakproofness of two layers of vacuum bag film is checked respectively.Start true
Sky pump vacuumizes the preform of fabric, and as pressure≤- 0.095MPa of bag film, pressurize 10min, pressure, which reduces, to be no more than
During 0.01MPa.Start vacuum pump, start as vacuum≤- 0.095MPa irrigate resin, when resin complete wetting fabric in advance into
After continuing injecting glue 25min after type body, injected rubber hose is closed with locking pliers.
Step 3: piecemeal molding structure machines
Each piecemeal molding structure demoulded in step 2 is machined out, the decomposing scheme obtained according to step 1 is each
Locating and machining groove or staggeredly groove, the partitioned organization after must processing are spare on piecemeal molding structure；
Step 4: partitioned organization pre-assembled
Partitioned organization after the processing obtained to step 3 carries out pre-assembled, assemble sequence according to the structure of raft frame or pedestal
For from top to bottom：Lower panel and longitudinal gusset, longitudinal gusset and horizontal gusset, top panel and floor in length and breadth；
Step 5: bonding plane roughening is handled
To treating that bonding plane carries out grinding process after pre-assembled in step 4, then cleaned out using acetone；
Step 6: partitioned organization is bonded
Preassembly sequence in step 4 is bonded, and in partitioned organization bonding plane coating adhesive, adhesive is room
Warm cured epoxy sqtructural adhesive, uses the scraping blade of one fixed width（Scraping blade width is advisable with being slightly less than groove width）In composite panel
Gluing of surfaces gluing, wherein in raft frame panel slot three faces should all uniform gluing, it is fixed first lower panel and transverse and longitudinal floor be bonded
Position, then carries out cemented in place to lower panel and transverse and longitudinal floor, is then bonded top panel；
Step 7: the filling of bonding transition region and bonding pad reinforcement formable layer
After the completion of being bonded in step 6, mixed and matched somebody with somebody with aerosil using epoxy construction adhesive or basis material
The putty put carries out adhesion zone right angle transition processing, and transition region filling section is isosceles right triangle or arc-shaped, so
Carry out reinforcement formable layer to bonding each junction afterwards, room temperature place 24 it is small when cure, reinforcement formable layer using hand paste into
Type technique or vacuum assisted resin injection moulding process, bonding pad strengthening course using carbon fiber or glass fibre as enhancement layer,
Using epoxy resin as base layer, and its weight 0.5%-3% is also added with epoxy resin sagging epoxy resin in order to prevent
Aerosil；Configuration ontology putty, resin use RIM135 and RIMH137, ratio 100:30, filler is gas phase two
Silica, putty are preferred with not trickling.After stirring evenly bonding cure after junction filling the section length of side be 10mm etc.
Waist right angled triangle transition region.
Reinforcing material uses high-strength satin weave glass fibre SW220B-90C, the length direction of fabric and the length phase of junction
Together, width is cut according to table 1, and every 15 layers are 1 group.After the completion of fabric cutting in 100 ± 5 DEG C of baking oven at drying
120 ± 10min is managed, seals fabric vacuum bag film after drying process.Using manual pasting forming process, will cut out successively
Glass fibre is placed on joint, and side glue-application-edge makes fiber be close to joint with scraper plate, ensures no starved, shows money or valuables one carries unintentionally, bubble is existing
As.By the fabric width distribution sequence of table, short fabric is cut in lower floor, it is then incremented by successively, make gentle transition at laying.
During laying, ensure that interlayer sticks closely, surfacing, does not have convex-concave fluctuation, after completing laying, then to overall progress
Appropriate finishing.
