Abstract
The invention relates to a lamination repairing method for a glass fiber reinforced plastics product. The lamination repairing method comprises the following steps of (1) forming a blind hole in a product body, wherein the inner end of the blind hole is connected to the inner end position in an inner cavity of a lamination defect; (2) fixing a vacuum bag film on an outer end surface of the lamination defect in a sealing manner by adopting a sealing adhesive tape; (3) connecting one end of an air suction conduit to the blind hole, connecting the other end of the air suction conduit to a vacuum pump, connecting one end of a resin guide pipe to a cavity between the vacuum bag film and the lamination defect, and connecting the other end of the resin guide pipe to a resin barrel; (4) starting the vacuum pump to ensure that the pressure intensity of the cavity between the vacuum bag film and the lamination defect is lower than or equal to 0.8 MPa, enabling resin to enter the cavity between the vacuum bag film and the lamination defect along the resin guide pipe under the action of negative pressure for uniformly infiltrating glass fibers, and finally infiltrating the resin to the inner end position in the inner cavity of the lamination defect; (5) after complete infiltration, closing the air suction conduit and the resin guide pipe; and (6) after the resin is cured, finishing lamination repairing.
Description
Technical field
The invention belongs to fiberglass production technical field, particularly relate to a kind of glass fiber reinforced plastics product layering method for repairing and mending.
Background technology
The reparation of traditional glass steel part lamination defect is polished off by angle, delamination area upper strata grinding machine, then in subfoundation, carry out hand by original laying and stick with paste repairing, then gel coat is sprayed, sanding and polishing, mending course very complicated, and bruting process produces a large amount of dust, have a strong impact on the uniformity of product external surfaces.
Summary of the invention
The present invention for solve in known technology the technical problem that exists and provide a kind of and simplify mending course, avoid dust to produce, improve product reparation after the glass fiber reinforced plastics product layering method for repairing and mending of presentation quality.
The technical scheme that the present invention takes for the technical problem existed in solution known technology is: a kind of glass fiber reinforced plastics product layering method for repairing and mending comprises the following steps, (1) on goods body, blind hole is offered, the inner through inner end positions to lamination defect inner chamber of blind hole; (2) sealing joint strip is adopted to be sealingly clamped on the outer face of lamination defect by vacuum bag film; (3) suction catheters one end is connected to blind hole, the other end is connected to vavuum pump in employing; Adopt and draw that resin duct one end is connected to cavity between vacuum bag film and lamination defect, the other end is connected to resin barrel; (4) vavuum pump is started, make the pressure≤0.8MPa of cavity between vacuum bag film and lamination defect, under suction function resin along draw resin duct enter cavity between vacuum bag film and lamination defect and in glass fibre homogeneous immersion, the final inner end positions infiltrated to lamination defect inner chamber; (5) complete wetting rear enclosed suction catheters and draw resin duct; (6) treat resin solidification, layering is repaired complete.
Advantage of the present invention and good effect are: method for repairing and mending of the present invention utilizes negative pressure of vacuum principle resin to be filled into lamination defect position and repairs to realize fast and high quality.Accelerate repairing speed, improve repairing quality, reduce production cost, improve fiberglass parts repairing surface of position quality.
Preferably: in step (3) between suction catheters and blind hole, draw between resin duct and the vacuum bag film run through and all adopt sealing joint strip to seal.

Detailed description of the invention
For summary of the invention of the present invention, Characteristic can be understood further, hereby lift following examples and be described in detail as follows:
Refer to Fig. 1, goods body 2 exists lamination defect 1, lamination defect 1 extends to goods body 2 inside.
Fig. 2 is the structural representation of lamination defect repair apparatus, can find out: repair technology comprises the following steps,
(1) on goods body 2, blind hole 3 is offered, the inner through inner end positions to lamination defect 1 inner chamber of blind hole 3;
(2) sealing joint strip is adopted vacuum bag film to be sealingly clamped on the outer face of lamination defect 1;
(3) adopt that suction catheters 5 one end is connected to blind hole 3, the other end is connected to vavuum pump 4; Adopt draw that resin duct 6 one end is connected to cavity between vacuum bag film and lamination defect 1, the other end is connected to resin barrel 8 with agitating device 7;
In this step in order to lift-off seal, ensure vacuum, arrange between suction catheters 5 and blind hole 3, draw between resin duct 6 and the vacuum bag film run through and all adopt sealing joint strip to seal;
(4) vavuum pump 4 is started, make the pressure≤0.8MPa of cavity between vacuum bag film and lamination defect 1, under suction function resin along draw resin duct 6 enter cavity between vacuum bag film and lamination defect 1 and in glass fibre homogeneous immersion, the final inner end positions infiltrated to lamination defect 1 inner chamber;
(5) complete wetting rear enclosed suction catheters 5 and draw resin duct 6;
(6) treat resin solidification, layering is repaired complete.
From said process, the method is easy and simple to handle, accelerates repairing speed, improves repairing quality, reduces production cost, improves fiberglass parts repairing surface of position quality.
Although with reference to previous embodiment to invention has been detailed description; for a person skilled in the art; it still can be modified to the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; within the spirit and principles in the present invention all; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
