Description
Technical field
The present invention relates to the vacuum assisted resin infusion device of composite.
Background technology
Fiber-reinforced resin class composite is more and more at present is applied to vacuum assisted resin infusion.Due to its whole technique mistake
Journey only needs the equipment by that can provide -0.08 ~ -0.1Mpa, and can completes resin during vacuum assisted resin infusion
Infiltration and solidification, it is not necessary to the huge autoclave of cost of investment, RTM equipment and molds, have that manufacturing cost is low, shaping efficiency
High, the advantages that porosity is low and intensity is high.
When vacuum imports shaping：
1）When surface fibre span, thickness, structure type etc. are different, vacuum suction resin delivery speed is uneven, easily causes
Regional area, resin are first drawn to discharging pipe end, form anti-package and dead angle, cause 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 is too 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, is disclosed including being placed in

Bag film, discharge nozzle are provided with the equipment for being used for vacuumizing, and flow-guiding screen segmentation lays, has been plated in and connect between some adjacent flow-guiding screens
Power feed pipe.
Further, it is 500~800mm that above-mentioned flow-guiding screen segmentation, which lays length,.
A kind of vacuum assistant resin infused for including above-mentioned vacuum assisted resin infusion device, including vacuum import resin forming step
Suddenly；
Vacuum, which imports resin forming step, includes segmentation importing resin steps；
I.e. resin from feed pipe after fiber cloth at first paragraph flow-guiding screen complete wetting to the 1st relay feed pipe；
It is then shut off feed pipe, then from the 1st relay feed tube,
Resin is from the 1st relay feed pipe through fiber cloth at second segment flow-guiding screen complete wetting to the 2nd relay feed pipe；
The rest may be inferred, until from last one of throat-fed, closes above other all charging aperture steps, and continue to complete into
Expect to all fibres cloth complete wetting step.
The beneficial effects of the invention are as follows：Design a kind of gradient progressively relay feed process, transition gradient material receiving tube, using leading
Drift net disconnects form layout, ensures that it synchronously feeds；
It is molded, is not limited by product compact dimensions by relay, vacuum forming technique can be used to prepare large-scale product product.

Embodiment
The invention will be further described 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, some relay charging apertures, discharging opening are provided with vacuum bag film
4, sealing strip 8 has connection to be used for the equipment vacuumized with for sealing vacuum bag film 9 on discharge nozzle 4（Do not drawn in figure）, wherein
The segmentation of flow-guiding screen 7 is laid, and relay feed pipe has been plated between every adjacent flow-guiding screen 7.
Referring to Fig. 2, vacuum assisted resin infusion device relay feed pipe structure figure（Sealing strip and vacuum bag film are not drawn, only
Limit fiber cloth 5, release cloth 6, flow-guiding screen 7, feed pipe, discharge nozzle layout）, it is segmented from charging aperture 1 to discharging opening 4 on release cloth 6
Provided with the 1st relay feed pipe 2 ..., last 1 relay feed pipe 3；If flow-guiding screen is divided into by each relay feed pipe simultaneously
Dry section.
The present embodiment：
1）Fiber cloth 5, release cloth 6, flow-guiding screen 7, feed pipe 1 and discharge nozzle 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；Water conservancy diversion
Such as figure segmentation of net 7 is plated in, spacing about 50mm；Relay feed pipe is plated in as schemed segmentation relay；Discharge nozzle 4 is nearby as schemed, flow-guiding screen 7
4~6cm is reduced 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 feed pipe 1, is vacuumized at discharge nozzle 4, when resin connects to the direction of discharge nozzle 4 infiltration the 1st
At power feed pipe 2, and complete wetting is fed at the 1st relay feed pipe 2 more than after more than 50mm, changing, and presss from both sides dead charging aperture
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 feed pipe
Place's charging, and press from both sides dead 1st relay feed pipe 2；
In this embodiment, when resin is guided at next road mouth of pipe along flow-guiding screen, regional area flow velocity can first reach soon,
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 mouth of pipe area from side is other
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 sucking
Up to terminal, 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 slow compared with large span resistance, the rate of adsorption, leaching
Moisten overlong time, the non-complete wetting of fiber cloth, the cured phenomenon of resin may be caused；Fed by relay, ensure per it is intersegmental across
Away from 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, causes
Each region feed rate is inconsistent, in fact it could happen that and local fiber has permeated completely, and separately has subregion not permeate situation,
And resin anti-package is ultimately caused, dead angle is partially formed 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 subregion is arrived in first infiltration
Domain, 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, can be fast
Speed, which is caught up with, first to be infiltrated to relay pipe, finally near relay pipe, is almost formed effect of advancing side by side, is passed 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 local first infiltration from being formed completely
Anti-package, or be partially formed dead angle and the unfavorable phenomenon such as can not thoroughly permeate.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should be included in the scope of the protection.
