Problems solved by technology

The core material of this processing method can be laid in the curved surface mold cavity, but in the process of vacuum infusion, in order to ensure the product quality, it is necessary to lay a diversion medium and the amount of glue in the groove is large, so that the waste of raw materials such as glue is serious. , this kind of core material processing method makes the glue flow and penetration speed uneven, and the outer surface of the workpiece is easy to form continuous small white spots, and the surface quality of the workpiece is poor.

Embodiment Construction

[0011] Below in conjunction with accompanying drawing, the present invention is described in detail, figure 1 It is a schematic diagram of the vacuum infusion of the core material using the processing method of the present invention. The whole infusion system is composed of a mold 101, a glass fiber 102, a sandwich material 103, a release cloth 104, a vacuum bag film 105, a sealant 106, an injection port 107 and an air extraction system. 108 composition, the diversion medium is removed during laying.

[0012] figure 2 , image 3 The upper surface and the lower surface of the core material 103 of the processing method of the present invention are described. The upper surface of the core material 103 is longitudinally cut grooves 201 at a certain interval, and the lower surface is horizontally cut grooves 201 at a certain interval and longitudinally added shallow grooves 203 . The depth of the groove is 1 / 2-4 / 5 of the thickness of the core material, and the width of the groo...

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 [0001] The invention relates to a core material of a large composite material component and a processing method thereof, in particular to a self-guiding type core material and a processing method thereof. Background technique [0002] Sandwich structures can be used to manufacture large composite components such as wind turbine blades, ships, aircraft, etc., and vacuum-assisted molding and other composite molding processes are usually used in the manufacturing process. That is to say, under the condition of certain negative pressure in the system, the glue solution is injected into the reinforcing material from the outside, and then solidified and formed. Among them, the sandwich material in the sandwich structure mainly plays the role of reducing the weight of the part and increasing the rigidity of the part, and the processing method of the sandwich material has a certain influence on the fluidity of the resin and the wettability of the enhanced material. ...
