Abstract
The invention relates to the field of forming of materials, and in particular relates to a composite material processing method. The composite material processing method comprises the following steps: preparing a mould, namely cleaning the mould, and then, removing mould wax by striking or removing mould water by wiping, wherein the surface of the mould has high hardness and lustre, and furthermore, at least 15cm of edge of the mould is reserved, so that a sealing strip and a pipeline are convenient to lay; constructing a gel coat surface, namely polishing a gel coat according to requirements of products, wherein orthophthalic, metaphenylene and vinyl types can be selected, and constructing the gel coat by using hand brushing and ejecting methods; and laying reinforcing materials, wherein glass fibre, carbon fibre and sandwich material can be selected as the reinforcing materials according to strength requirements of the products. The composite material processing method disclosed by the invention is high in processing efficiency and low in production cost; and the processing quality of parts is ensured.
Description
Technical field
The present invention relates to forming materials field, be specifically related to the processing method of composite.
Background technology
In current material, composite is widely used because its light weight is high-strength, and in use better performances.Manufacturing process for composite is also constantly improving and innovation.Stuck with paste by hand originally, develop into the injection of mechanization, pultrusion, the techniques such as mold pressing, but these some problems of processing method ubiquity, working (machining) efficiency and the crudy of part always have much room for improvement, and increase flesh production cost.
Summary of the invention
In order to solve the problem, the invention provides a kind of raising working (machining) efficiency, reducing production cost, ensure the processing method of the composite of part crudy.
The processing method of composite of the present invention, comprises the following steps:
The first step, prepare mould, will there be higher hardness and higher gloss in surface, and die edge at least retains 15 centimetres, is convenient to the laying of sealing strip and pipeline, cleans out mould, then plays demoulding wax or smears demoulding water;
Second step, construction gel coat face, according to the requirement of goods, with product gel coat and polishing gel coat, selects type to have adjacent benzene, isophthalic and vinyl, with the method construction gel coat of hand brush and injection;
3rd step, reinforcing material is laid and is selected reinforcing material glass fibre, carbon fiber, Sandwich materials, and this will require to determine according to product strength;
4th step, vacuum bag material is laid and is first spread release cloth, and being then flow-guiding cloth, is finally vacuum bag, before the vacuum bag that closes, thinks over the trend of resin and vacuum-pumping pipeline, is very careful during laying, in order to avoid some sharp objects puncture vacuum bag;
5th step, vacuumizes after having spread these materials, checks and respectively enters pitch tube, vacuumize whole system, as far as possible evacuating air in system;
6th step, resin prepares resin, allocates corresponding curing agent into by gel time after vacuumizing and reaching certain requirement;
7th step, imports resin and inserts in the resin barrel prepared entering resin pipeline, open switch successively according to charge order, note the amount of resin barrel, and supplement in time;
8th step, demoulding resin gel is cured to a certain degree, throws off vacuum bag material, takes out goods and carry out post processing from mould;
Working (machining) efficiency of the present invention, reduces production cost, ensures part crudy.
Detailed description of the invention
The processing method of composite of the present invention, is characterized in that, comprises the following steps:
The first step, prepare mould, will there be higher hardness and higher gloss in surface, and die edge at least retains 15 centimetres, is convenient to the laying of sealing strip and pipeline, cleans out mould, then plays demoulding wax or smears demoulding water;
Second step, construction gel coat face, according to the requirement of goods, with product gel coat and polishing gel coat, selects type to have adjacent benzene, isophthalic and vinyl, with the method construction gel coat of hand brush and injection;
3rd step, reinforcing material is laid and is selected reinforcing material glass fibre, carbon fiber, Sandwich materials, and this will require to determine according to product strength;
4th step, vacuum bag material is laid and is first spread release cloth, and being then flow-guiding cloth, is finally vacuum bag, before the vacuum bag that closes, thinks over the trend of resin and vacuum-pumping pipeline, is very careful during laying, in order to avoid some sharp objects puncture vacuum bag;
5th step, vacuumizes after having spread these materials, checks and respectively enters pitch tube, vacuumize whole system, as far as possible evacuating air in system;
6th step, resin prepares resin, allocates corresponding curing agent into by gel time after vacuumizing and reaching certain requirement;
7th step, imports resin and inserts in the resin barrel prepared entering resin pipeline, open switch successively according to charge order, note the amount of resin barrel, and supplement in time;
8th step, demoulding resin gel is cured to a certain degree, throws off vacuum bag material, takes out goods and carry out post processing from mould;
The present invention has following characteristics: more high-quality goods: resin infiltrates glass under vacuum conditions, compared with conventional fabrication processes, bubble in goods is few, do not stay unnecessary resin in system, glass fiber content is very high, when can reach 70%, even lower, resulting product weight is lighter, and intensity is higher, and asking of criticizing and criticize is also highly stable; Less resin loss: the consumption of resin of the present invention can accurately budget, sticks with paste or spray technology for hand, though can be restive because of the polytropy of operator, like this can be cost-saving; Resin distribution is even, for goods. and the pressure that the vacuum of different piece produces is consistent, and therefore resin reaches unanimity to the unrestrained profit speed of glass and content; Process volatilization is less: do not have brush or roller and so in production process, can not cause splashing or drip phenomenon discovery of resin.
