Abstract
The invention discloses a self-guide flow type core material and a processing method thereof. The core material is grooved in two sides, an upper surface is longitudinally grooved according to a core material thickness; a lower surface is horizontally grooved according to the core material thickness and has shallow groove in longitudinal; the core material obtained by the processing method provided by the invention can be widely applied to a planar die cavity and a curved die cavity, is suitable for composite material molding technique such as vacuum auxiliary injection molding; the guild flow medium is not paved in the material molding process so as to reduce the glue solution waste since the auxiliary material absorbs the resin while saving material.
Description
Technical field
The present invention relates to a kind of large-scale composite material member core and processing method thereof, particularly a kind of Self-guide flow type core material and processing method thereof.
Background technology
Sandwich can be used for making the parts of large-scale composite material member such as wind electricity blade, boats and ships, aircraft etc., usually adopts the composite material process plannings such as vacuum assisted molding moulding in manufacturing process.Be system under the condition of certain negative pressure, glue is injected in reinforcing material by the external world, then curing molding.Wherein the sandwich material in sandwich has mainly played and has alleviated product weight, increase the effect of product rigidity intensity, and the processing method of sandwich material has certain impact to Resin Flow, reinforcing material wellability.Produce at present upper most widely used sandwich material processing method and mainly contain two kinds of mode of grooving, the first is shallow slot, namely press certain spaced shallow slot, punching on two surfaces, core up and down, although the core groove gel content of this kind processing method is less, but core can not be crooked in the lay process, can only be used for the plane product, limitation is larger, and the core that therefore usually claims this kind processing method is that sandwich material is dull and stereotyped.The second is grooving, namely presses certain spacing joint-cutting at the upper surface of core, and the joint-cutting degree of depth is core thickness, then presses the constant spacing punching at the core upper surface, and lower surface is adhesively fixed core together with the composite felt.The core of this kind processing method can be layed in the curved surface die cavity, but in the priming by vacuum process, for guaranteeing product quality, need to lay the interior gel content of permeable medium and groove more, make the waste of raw materials such as glue serious, in addition, this kind core processing method makes that glue flows, the seepage velocity heterogeneity, the product outer surface easily forms the little hickie of continuity, and the product surface quality is poor.
Summary of the invention
The present invention mainly improves the sandwich material processing method, has solved laying limitation and deficiency that above-mentioned two kinds of core processing methods are brought.
The present invention relates to a kind of Self-guide flow type core material and processing method thereof, described processing method is core upper surface vertical grooving at a certain distance; The core lower surface is horizontal grooving and vertically add shallow slot at a certain distance, and cutting groove depth is the 1/2-4/5 of core thickness, and notch width is 0.5-1.5mm; The shallow slot degree of depth is 1-2mm, and the shallow slot width is 1-2mm.The separation of the vertical grooving of upper surface equates, and equates with the separation of the horizontal grooving of lower surface and vertical shallow slot.The line of rabbet joint of the vertical shallow slot of lower surface is positioned in the middle of the vertical grooving separation of upper surface.
In use procedure, core upper and lower surface grooving is resin flow channel, also helps bubble and discharge when guaranteeing resin flows.In addition, the degree of depth of grooving is conducive to core bending, distortion, can fit closely with the curved surface die cavity, and the width of grooving is conducive to the discharge of flowing of resin and bubble.The lower surface shallow slot has played the effect of resin flows and bubble discharge on the one hand, has also played on the other hand the effect of balance core upper and lower surface resin flows speed, thereby has effectively solved the problem of the local packet flow of product outer surface.
The core that the present invention makes uses extensively, all can use at plane die cavity and curved surface die cavity, and can not lay permeable medium in process of deployment, also reduced the glue waste that produces because of auxiliary material absorption resin when saving material, enhancing productivity.It uses flow process to be: die cavity is prepared, glass is laid, sandwich material is laid, glass is laid, the bonding plane release cloth is laid, injecting glue line arrangement, the sealing of vacuum bag film, glue perfusion.

Fig. 3 is the lower surface schematic diagram of the core processing method of the embodiment of the present invention;
Wherein: the shallow slot, 204 of the grooving, 203 of the grooving, 202 of 101-mould, 102-glass, 103-sandwich material, 104-release cloth, 105-vacuum bag film, 106-fluid sealant, 107-injection port, 108-extract system, 201-vertically-laterally-vertically-be core upper and lower surface is in length and breadth to the intersection point of grooving.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is done and illustrate, Fig. 1 is the priming by vacuum schematic diagram that uses processing method core of the present invention, whole filling system is comprised of mould 101, glass 102, Sandwich materials 103, release cloth 104, vacuum bag film 105, fluid sealant 106, injection port 107 and extract system 108, has removed permeable medium in process of deployment.
Fig. 2, Fig. 3 have described upper surface and the lower surface of processing method core 103 of the present invention.The upper surface of core 103 is vertical grooving 201 at a certain distance, and lower surface horizontal grooving 201 at a certain distance also vertically adds shallow slot 203.Cutting groove depth is the 1/2-4/5 of core thickness, and notch width is 0.5-1.5mm; The shallow slot degree of depth is 1-2mm, and the shallow slot width is 1-2mm.
The separation of the vertical grooving of upper surface equates, and equates with the separation of the horizontal grooving of lower surface and vertical shallow slot.The line of rabbet joint of the vertical shallow slot of lower surface is positioned in the middle of the vertical grooving separation of upper surface.
Wherein grooving 201,202 and shallow slot 203 all play the effect that resin water conservancy diversion and gas are discharged, except grooving 201,202 has in addition also played effect with type, core is can arbitrary deformation crooked, fit closely with die cavity, and shallow slot 203 has guaranteed the flow velocity homogeneous of resin at core upper and lower surface longitudinal direction, has promoted the quality of product outer surface.Hole 204 be the core upper and lower surface in length and breadth to the intersection point of grooving, be mainly the passage of resin infiltration.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement are within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claim was defined.
