Abstract
The invention belongs to the field of aviation technology and relates to an unmanned plane, especially to an automatic heating and pressurization production process for a composite material specially used for a small-sized unmanned plane. The production process comprises the following steps: preparing a die; pretreating a prepreg; laying and molding the composite material specially used for the small-sized unmanned plane; and carrying out demolding to take out a finished product. According to the production process provided by the invention, unsafe equipment like a pressure pan is omitted, the produced product has great strength, light weight per unit area and good surface smoothness, and production efficiency is substantially improved. An airplane made from the material prepared by using the production process has the advantages of a light weight, small consumption of power, great thrust, high mechanical strength and small noise.
Description
Technical field
The invention belongs to the aeronautical technology field, relate to unmanned plane, especially relate to a kind of pressurization production technology of certainly heating of SUAV composite material special.
Background technology
China's SUAV industry is started late, generally be with reference to external active service unmanned plane design aspect the equipment of profile, specification and lift-launch in the design process, but the composite manufacture craft horizontal aspect design route outmoded, cause some model unmanned planes the aspects such as body weight, structural design and the strength of materials with external nineties like product approximate, quantum jump too not.
In recent years, new technology and the new material development of China's composite industry are very fast, composite is a kind of brand-new material, be in developing stage in the aircraft application, because of its material light weight, excellent in cushion effect, temperature deformation is little (" creep " that the difference of Yin Wendu causes), anti-aging (serviceable bife prolongation), the characteristics such as anticorrosion, thunder and lightning, static and various storeroom compatibility height are used very extensive in many industries.
The manufacture craft of China's SUAV composite is at present, at first draw drawing＞sample making＞manual formpiston＞turn over fiberglass former processed＞making sample＞modification mould＞again make sample＞moulded products＞surface treatment＞spray paint＞process again＞spray paint＞polish, namely after body production is finished, carry out at last surface lacquer work, and the dope layer of spraying can make body weight increase, this technique is namely taken a lot of work and is time-consuming, total duration needs about 30 days, and mass production management degree is complicated.。
Summary of the invention
The problem to be solved in the present invention is to overcome the deficiencies in the prior art part, and a kind of pressurization production technology of certainly heating of SUAV composite material special is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of pressurization production technology of certainly heating of SUAV composite material special is characterized in that: may further comprise the steps:
Step 1: preparation mould: with computer drawing mould drawing, then carry out the processing (comprising curved surface and corner angle) of mould, carry out again mould repeatedly polishing until fineness meet the demands; Mould comprises formpiston and former, and in vertical face cooling water hole and the heating wire hole of above-mentioned formpiston and former, described cooling water hole and heating wire hole are for being spaced; Leave overflow glue groove and vacuum orifice at the formpiston back side;
Step 2: preliminary treatment: preimpregnation cloth is cut into required form and size, and carry out stackingly according to thickness requirement, then lay reinforced composite at preimpregnation cloth, and the smooth and deburring with paver;
Step 3: moulding: the pretreated preimpregnation cloth of having laid reinforced composite of step 2 is put into the described mould of step 1; Matched moulds; Sealing surface adds sealing ring between former and formpiston; Unitary mould is served hydraulic press pressurize, meanwhile carry out mold heated, after preimpregnation cloth glue thoroughly dissolves, vacuumize operation;
Step 4: treat that mold temperature rises to 220 when spending, continue half an hour after stopped heating, carry out cold water injection to mould water channel, carry out the demoulding when treating mold cools down to normal temperature, take out finished product.
Further, the material of described mould is metal.
Further, before carrying out that step 3 is described preimpregnation cloth is put into mould, first mould inner wall is sprayed releasing agent, again at former inwall spray surface lacquer.
Further, described reinforced composite comprises honeycomb paper and metal beehive material.
Advantage and good effect that the present invention has are: production technology provided by the present invention has saved the dangerous equipment such as pressure pan, and the product strength of producing is large, unit are lightweight, and surface smoothness is good, has greatly improved production efficiency; The aircraft that the material that goes out with this explained hereafter is done is not only light and handy, and consumption of power is few, and thrust is large, and mechanical strength is high, and noise is little.
