Rear is bonded flange laying, and rear after laying, which is bonded in flange laying, is laid with vacuum system, vacuum infusion resin, directly
It to resin complete wetting laying, is heating and curing, rear bonding flange is obtained after demoulding；
2) shell laying is carried out in suction side shell or pressure side housing mould, by rear bonding flange in suction side shell
The posterior border position of body or pressure side housing mould is combined with shell laying by Vacuum infusion molding process bonding, after being had
The suction side shell or pressure side shell of edge bonding flange；
3) by with rear bonding flange suction side shell or pressure side shell rear with not with the Nian Jie flange of rear
Pressure side shell or suction side shell rear bonding；
4) similarly press step 1) -3) method, obtain with leading edge bonding flange suction side shell or pressure side shell
Suction side shell leading edge and pressure side shell leading edge are bonded, obtain wind electricity blade by body.
Preferably, step 3) the pressure side shell or suction side shell not with rear bonding flange is led using vacuum
Enter moulding technology manufacture.
Preferably, the step 1) method for being laid with vacuum system are as follows: a circle sealant is pasted at bonding flange laying edge,
It is bonded flange laying upper surface laying release cloth, is laid with upper surface flow-guiding screen and upper surface air-exhausting bag in release cloth upper surface, so
Sealing vacuum bag film is laid on entirely bonding flange mold afterwards, and sets the gum-injecting port in shaping mold cavity and vacuum suction
Mouthful, vacuumize holding vacuum degree≤≤ -0.098Mpa.
Preferably, the adhering method of step 3) the suction side shell rear and pressure side shell rear are as follows: viscous in rear
Smearing structure glue on acting flange, by structure glue by with rear be bonded flange suction side shell or pressure side shell rear with
Not with the pressure side shell or suction side shell rear bonding of rear bonding flange.
Preferably, before step 3) the suction side shell rear is Nian Jie with pressure side shell rear, first by leading edge web
It is adhered respectively on suction side shell and pressure side shell with the both ends of rear web.
Preferably, the method for step 4) the suction side shell leading edge and pressure side shell leading edge bonding are as follows: viscous in leading edge
Smearing structure glue on acting flange, by structure glue by with leading edge be bonded flange suction side shell or pressure side shell leading edge with
Not with the pressure side shell or suction side shell leading edge bonding of leading edge bonding flange.
Preferably, the step 1) core material is Ba Shamu, polyvinyl chloride or polyethylene terephthalate.
The both ends of leading edge web and rear web of the present invention are equipped with bonding flange, the flange of leading edge web and rear
The both ends of leading edge web and rear web are adhered respectively to suction side shell and pressure side by structure glue by upper smearing structure glue
On shell.
