Infiltration and solidification, it is not necessary to invest huge autoclave, and the technologies such as suture, braiding can be combined and realize composite element
Three-dimensional enhancing, have the advantages that manufacturing cost is low, shaping efficiency is high, porosity is low and good integrity.
When vacuum imports shaping：
1）When surface fibre span, thickness, structure type etc. are different, vacuum suction resin delivery speed is uneven, easily
Cause regional area, resin is first drawn to discharging pipe end, forms anti-package and dead angle, causes the infiltration of Local Dry area impermeable；
2）When span is larger, resin from one end infiltrate to the other end when, by the heavy resistance such as fiber cloth, absorption affinity mistake
Small, water conservancy diversion is too slow, is unfavorable for operating.
China Patent Publication No. is 206154744U, the double membrane forming devices of entitled vacuum aided, disclose including

Between be provided with flow-guiding screen and bleeding point.It is also without solution above-mentioned technical problem.
The content of the invention
The present utility model provides a kind of vacuum assisted resin infusion device saved resin, reduce cost.
The technical solution of the utility model is：
A kind of vacuum assisted resin infusion device of composite, including the fiber cloth being placed on mould, fiber cloth is successively by inner
Release cloth, flow-guiding screen and vacuum bag film are outwards laid, charging aperture and discharging opening are provided with vacuum bag film, sealed strip is used for close
Envelope vacuum bag film, discharging opening are provided with the equipment for being used for vacuumizing, and flow-guiding screen segmentation is laid, between some every adjacent flow-guiding screens
It has been plated in relay feed pipe.
Further, it is 500~800mm that above-mentioned release cloth segmentation, which lays length,.
The beneficial effects of the utility model are：A kind of gradient progressively relay feed process is designed, transition gradient material receiving tube, is adopted
Form is disconnected with flow-guiding screen to be laid out, and ensures that it synchronously feeds；

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, vacuum assisted resin infusion device, including the fiber cloth 5 being placed on mould, fiber cloth 5 is successively from inside to outside
Release cloth 6, flow-guiding screen 7 and vacuum bag film 9 are laid, charging aperture 1 and discharging opening 4 are provided with vacuum bag film, sealing strip 8 is used for close
Vacuum bag film 9 is sealed, has connection to be used for the equipment vacuumized on discharging opening 4（Do not drawn in figure）, wherein flow-guiding screen 7, which is segmented, lays,
Relay feed pipe has been plated between per adjacent flow-guiding screen 7.
Referring to Fig. 2, relay feed pipe floor map
Vacuum assisted resin infusion device relay feed pipe structure figure（Sealing strip and vacuum bag film are not drawn, only limit fiber cloth
5th, release cloth 6, flow-guiding screen 7, feed and exhaust tube layout）, from charging aperture 1 to discharging opening 4, segmentation is provided with the 1st relay on release cloth 6
Feed pipe 2 ..., last 1 relay feed pipe 3；Flow-guiding screen is divided into some sections by each relay feed pipe simultaneously.
The present embodiment：
1）Fiber cloth 5, release cloth 6, flow-guiding screen 7, charging aperture 1 and discharging opening 4 are completed by drawing；
Fiber cloth 5 is plated in by product size, thickness requirement design；The side amplification more each than fiber cloth of release cloth 6 about 50mm is plated in；
Such as figure segmentation of flow-guiding screen 7 is plated in, spacing about 50mm；Relay feed pipe is plated in as schemed segmentation relay；Discharging opening 4 nearby as schemed, is led
Drift net 7 reduces 4~6cm than fiber cloth 5；
2）The good sealing strip 8 of cloth, vacuum bag film 9 etc.；
3）Vacuum imports resin forming
Resin is initially fed at charging aperture 1, is vacuumized at discharging opening 4, when resin infiltrates the 1st to the direction of discharging opening 4
At road relay feed pipe 2, and complete wetting more than after more than 50mm, change at the 1st relay feed pipe 2 feed, and press from both sides extremely enter
Material mouth 1；When equally, at the relay feed pipe of resin complete wetting the 2nd, and more than after more than 50mm, changing from the 2nd relay
Fed at expects pipe, and press from both sides dead 1st relay feed pipe 2；
The rest may be inferred, until being fed from last 1 relay feed pipe 3, and clamps above other all charging apertures, and ensureing
Last fiber all infiltrates.
In this embodiment, when resin is guided at next road mouth of pipe along flow-guiding screen, regional area flow velocity soon can be first
Reach, and because flow-guiding screen interrupts, no flow-guiding screen region flow velocity flow velocity is greatly reduced, and resin does not preferentially arrive at pipe from side is other
Mouth region domain quickly introduces along flow-guiding screen, finally can almost allow resin subsynchronous again in disconnection water conservancy diversion web area, avoid part from first inhaling
It is complete to reach home, anti-package and dead angle are formed, causes the infiltration of Local Dry area impermeable.
Beneficial effect：
1）Fed by relay, large-scale product product can be molded；
When product is excessive, span is excessive between feed and exhaust tube, and resin passes through can be very compared with large span resistance, the rate of adsorption
Slowly, infiltrating time is long, may cause the non-complete wetting of fiber cloth, the cured phenomenon of resin；Fed by relay, ensure every section
Between span in 500~800mm, each section can well feed, water conservancy diversion, profit leaching；
2）When directly using segmentation relay charging, because product may be in irregular shape, fibrous layer is plated in variable thickness cause,
Cause each region feed rate inconsistent, in fact it could happen that local fiber has permeated completely, and separately has subregion not permeate situation
Occur, and ultimately cause resin anti-package, be partially formed dead angle and the unfavorable phenomenon such as can not thoroughly permeate；
By the way that by each relay feed pipe, flow-guiding screen interrupts, ensure at each charging pipeline section, relay pipe portion is arrived in first infiltration
Subregion, because flow-guiding screen separates, wet-out rate is greatly reduced, and not being guided to relay area under control domain has flow-guiding screen water conservancy diversion, and speed is fast,
It can quickly catch up with and first infiltrate to relay pipe, finally near relay pipe, almost form effect of advancing side by side, pass through each relay
Area under control domain resin wet-out rate keeps balance, to ensure that the final wet-out rate of product almost maintains an equal level, prevents that local first infiltration is complete
Anti-package is formed, or be partially formed dead angle the unfavorable phenomenon such as can not thoroughly permeate.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for this
For the technical staff in field, the utility model can have various modifications and variations.It is all in the spirit and principles of the utility model
Within, any modification, equivalent substitution and improvements made etc., it should be included within the scope of protection of the utility model.
