After water conservancy diversion inclined-plane enters collecting tank 101, passes sequentially through drain hole 81 and resin duct II 32 enters resin trap 10.
The molding work of space fabric composite material is carried out using above-mentioned high-performance fiber space fabric and resin compounded device
The specific work process of skill is as follows：
Note：Used space fabric is glass fibre space fabric.
1, it pre-processes：
1.1, glass fibre space fabric is cut；The smearing release agent on top board 6, stay 7 and lower pallet 8.
1.2, the stay 7 for coating releasing agent is positioned between the selvedge of the glass fibre space fabric both sides cut
In interval, the clearance space (as shown in Figure 3) of the glass fibre space fabric is strutted.
1.3, smooth being placed on of glass fibre space fabric that space structure is strutted obtained by step 1.2 is coated with releasing agent
Lower pallet 8 on；And telescopic prop 1 is adjusted by control panel 13, between so that the top board 6 for being coated with releasing agent is smoothly pressed in
Every on fabric, at this point, top board 6 is close to glass fibre space fabric upper surface, lower pallet 8 under glass fibre space fabric
Surface is close to, and the clearance space of glass fibre space fabric is opened completely.Close cabinet door.
The pressure that the present invention is pushed according to top board 6 controls depression degree, by repeatedly flattening experiment obtains different thickness
The pressure when flattening of the space fabric of degree, then typing control panel 13, utilizes control panel in practical work process
The corresponding pressure of 13 selection space fabric thickness；The pressure signal detected is sent to control plane by pressure inductor 14
Plate 13, the pressure that the pressure that 14 detected pressure head 15 of pressure inductor pushes, as top board 6 push, when the pressure reaches this
When pressure set by the space fabric of thickness, control panel 13 controls 1 stop motion of telescopic prop, to make top board 6
Stop pressurization.
Note：Pressure when pressing refers to the pushing of top board 6, and top board 6 is made to give the pressure of space fabric upper surface (at present
Supporting plate 8 gives the pressure of space fabric lower surface), to make its clearance space open completely；
Clearance space is opened completely to be referred to：The vertical yarn of space fabric stretches, and is rolled tiltedly without fold or to a certain, and hang down
Continuous hole between yarn is clear, and the gauge between hole and hole is equal, and it is whole vertical with top and bottom layer that knot connects yarn.
Top board 6 can be enabled to give the pressure of 1.2~2Mpa of space fabric according to actual needs, to keep its clearance space complete
It is complete to open, enable top board 6 give the pressure of glass fibre space fabric upper surface 1.2MPa, while lower pallet 8 in the present embodiment
The pressure for giving glass fibre space fabric lower surface 1.2MPa enables the glass fibre space fabric clearance space open completely.
2, impregnation steps：
2.1, vacuum pump 11 is opened by control panel 13, vacuum pump 11 will vacuumize in babinet, and ensure entire work
Vacuum state is kept in process case.
Note：It vacuumizes for being drained to resin, makes not retain resin in the gap between vertical yarn, be additionally operable to reduce interval
Bubble in fabric, to improve the quality of resin infusion, infiltration.
Vacuumizing only needs to realize to resin drainage and reduce the function of bubble in space fabric, vacuum in the present embodiment
Degree is 0.1MPa,
2.2, the valve at 4 liquid outlet of resin reservoir is opened by control panel 13, the resin in resin reservoir 4 is logical
Excess pressure and the effect of gravity pass sequentially through valve, resin duct I 31 and deflector hole 61 and enter 100 in placement cavity, set at this time
Fat is spread rapidly by glass fibre space fabric of the diversion trench 62 on lower pallet 8.Until the resin complete wetting interval is knitted
Object, and when flowing to resin trap 10 by resin duct II 32, close the valve at 4 liquid outlet of resin reservoir.
During above-mentioned resin infiltration glass fibre space fabric, vacuumize between not only assisted resin sized glass fibres
Every fabric, glass fibre space fabric is also made to be in vacuum state, it is effective to reduce the last gas prepared in gained compound fabric
Bubble；Resin is diffused by diversion trench 62, is recycled by resin trap 10 after complete wetting glass fibre space fabric,
Not only avoiding existing artificial smearing resin leads to the non-uniform problem of resinous coat, also as save resource, reduce work at
This.
Note：After extra resin enters collecting tank 101 along water conservancy diversion inclined-plane, drain hole 81 and resin duct II are passed sequentially through
32 enter resin trap 10.
Space fabric only by resin infiltration and cures the composite material that could be formed and have hardness.
Complete wetting refers to upper layer of fabric, layer fabric and the intermediate vertical yarn of resin infiltration space fabric.The present invention passes through
It vacuumizes, resin is allowed quickly to flow, to fully infiltrate space fabric.
Space fabric be can determine that when resin flow to resin trap 10 by resin duct II 32 by resin infiltration, in reality
In the course of work of border, the valve at 4 liquid outlet of resin reservoir can be turned off after 1~2 point of persistent collection resin as needed, from
And ensure space fabric complete wetting, the bubble inside resin can be fully eliminated, product quality is improved.
3, heat setting step：
Heater 2 is opened by control panel 13.
4 heaters 2 are used in the present embodiment, two are located at top of the box, and two are located at the bottom of box, to realization pair
The glass fibre space fabric of step 2.2 gained impregnating resin is heated.Heating process is specially：
The glass fibre space fabric of impregnating resin in the case where whole process keeps vacuum state (0.1MPa), in room temperature (25 DEG C) with
1.5 DEG C/min heating rates are warming up to 120 DEG C, keep heating 4 hours at such a temperature, enable the glass fibre interval of impregnating resin
Fabric curing molding obtains space fabric resin compounded fabric (hereinafter abbreviation compound fabric).
Note：Glass fibre space fabric is in the state of high temperature and pressure during resin solidification, to reinforced resin
The solidification of resin has been also speeded up to assign composite material excellent mechanical property to the adhesion of fabric, has improved production effect
Rate.
Above-mentioned high pressure refers to pressure of the top board 6 to glass fibre space fabric.
4, it post-processes：Vacuum pump 11 and heater 2 are closed by control panel 13, and opens wind turbine 5；Chamber door is opened, etc.
Taking-up compound fabric is cooled to room temperature at a temperature of cabinets cavity.
Finally, it should also be noted that it is listed above be only the present invention several specific embodiments.Obviously, this hair
Bright to be not limited to above example, acceptable there are many deformations.Those skilled in the art can be from present disclosure
All deformations for directly exporting or associating, are considered as protection scope of the present invention.
