The manufacture process can be used for manufacturing products with lighter weight and higher strength at a higher accuracy and a higher speed. In addition, the manufacture process ensures that the technique cost and the material cost during batch production are lowered.
Description
Technical field
The present invention relates to a kind of manufacturing process, particularly a kind of manufacturing process of composite felt formula fabric.
Background technology
In the prior art, each manufacturer mainly uses the glass fibre bi-axial fabric, all need to spend when the unified thickness 7.5-8mm. of product makes at every turn after the moulding more than 6 hours in order to the shop layer for reaching, because common 0/90 or similar twin shaft be every layer of 0.6-0.8m m to the thickness of weaving cotton cloth, each parts all needs to repeat shop layer for every square metre 8-10 time.The time in early stage that whole moulding process consumed has accounted for 70%.When making large component, this method of the prior art deposit labor intensive many, drop into the shortcoming more than the auxiliary material.
Summary of the invention
The purpose of this invention is to provide a kind of manufacturing process that can produce the composite felt formula fabric of light and intensity is high and can reduce enterprise technical costs and material cost.
For solving the problems of the technologies described above, the present invention takes following technical scheme: a kind of manufacturing process of composite felt formula fabric is characterized in that:
May further comprise the steps:
(1) prepares mould;
(2) the gel coat surface construction is carried out on the surface of mould;
(3) lay reinforcing material;
(4) lay vacuum bag material: at first spread release cloth, lay flow-guiding cloth then, lay vacuum bag at last;
(5) laid various materials in the described step (4) after, the system that whole steps (4) is set up is carried out vacuum pumping;
(6) after the described operation that vacuumizes in the described step (5) reaches certain requirement, begin to prepare the preparation resin;
(7) import the resin of preparation in the described step (6) in the described system handled of the step of passing through (5);
(8) demoulding.
Described manufacturing process guarantees product quality by two-way technology, and a large amount of auxiliary material have been saved, therefore, be a great technological improvement not only to the present formula of knocking open manual pasting forming process, and compare with two kinds of mold closing technologies of current popular, described worker artistic skill adopts higher precision, the product that faster speed is made is lighter, intensity is higher.In addition, under situation about producing in batches, described manufacturing process can also reduce the technical costs and the material cost of enterprise.
The specific embodiment
Below technical scheme of the present invention is elaborated.
The manufacturing process of the composite felt formula fabric among the present invention may further comprise the steps:
(1) prepares mould
High-quality mould also is necessary concerning manufacturing process.Specifically, will there be higher hardness and higher gloss in the surface of mould, and die edge keeps 15 centimetres at least, is convenient to the laying of sealing strip and pipeline.
Prepare mould and comprise mould is cleaned out, play demoulding wax then or smear substep such as demoulding water.
(2) carry out the gel coat surface construction
According to product requirements, can carry out product gel coat and polishing gel coat, available gel coat material has adjacent benzene, a benzene and/or vinyl.The method of hand brush and injection is adopted in the construction of described gel coat face.
(3) lay reinforcing material
Described reinforcing material can be glass fibre, carbon fiber or sandwich material.The selection of described reinforcing material can be determined according to the requirement to product strength.Though all fabrics can be used, different materials and weave can influence the flow velocity of resin.
(4) lay vacuum bag material
Specifically, at first spread release cloth, lay flow-guiding cloth then, lay vacuum bag at last.
Before the described vacuum bag that closes, consider the trend of resin and vacuum-pumping pipeline, otherwise resin can can't soak into some place.
Should avoid sharp object to puncture described vacuum bag when in addition, laying vacuum bag.
(5) vacuumize
After having laid the various materials in the described step (4), clamp each resin feeding pipe, the system that whole steps (4) is set up is carried out vacuum pumping then, the air in the described system is found time as far as possible, and checks the air-tightness of described system; If there is leak source to exist, when importing resin, air also can advance body thereupon and go in the described system, so the bubble that forms can might be scrapped by whole goods even at the leak source place to other local infiltration.
(6) preparation resin
After the described operation that vacuumizes in the described step (5) reaches certain requirement, begin to prepare the preparation resin.Described resin can be selected epoxy resin or unsaturated polyester resin.
During the preparation resin, should allocate corresponding curing agent into by gel time.The resin that general vacuum imports all contains the curing indicator, can judge whether to have added curing agent from color.
(7) import the resin of preparing in the described step (6)
The pipeline of resin feeding pipe is inserted in the resin bucket for preparing, and open clip on the pipeline of each resin feeding pipe according to the order of charging successively, in this process, should be noted that the residual resin amount of resin bucket and in time replenish resin.
(8) demoulding
After predetermined degree, throw off described vacuum bag etc. the resin solidification that imports in the described step (7).
Then, take out goods and carry out post processing from mould.Described post processing comprises:
(a) goods after using the polyester line with the demoulding carry out tape edge;
(b) goods behind the tape edge in the step (a) are cut the back rolling.
Preferably, described manufacturing process also is included in the step that yarn is sprayed on the surface of the material of described reinforcing material.
Described manufacturing process guarantees product quality by two-way technology, and a large amount of auxiliary material that vacuumize have been saved, therefore, be a great technological improvement not only to the present formula of knocking open manual pasting forming process, and compare with two kinds of mold closing technologies of current popular, described worker artistic skill adopts higher precision, the product that faster speed is made is lighter, intensity is higher.In addition, under situation about producing in batches, described manufacturing process can also reduce the technical costs and the material cost of enterprise.
Preferably, described manufacturing process can be used for solid composite felt formula glass fabric.Adopt the glass fabric of the fabrication process among the present invention owing to adopted manufacturing process, therefore, good, the no steam bubble of compactness has light weight, advantages of high strength in the process of its moulding.
