Background technique
With the continuous development of space exploration technology and the raising of technical requirement, the bore of antenna reflective face is increasingly
Greatly, the required precision of type face is higher and higher, and carbon fibre composite obtains in satellite antenna since its specific strength is high, specific stiffness is big
A large amount of application is arrived.Reinforcing fiber has good electric conductivity in carbon fibre composite, but due to resin in composite material
The reason of matrix conductive rate difference causes the conductance of composite material entirety to decline, is equivalent to semiconductor, therefore to meet high-precision day
The use demand in line reflection face, inside panel surface must metallize, and when satellite antenna is run in track, surface is inevitable
The irradiation that will receive sunlight, it is necessary to control metal layer to the absorptivity and emissivity of sunlight, to meet metallization and control
The absorptivity-emissivity ratio of sunlight processed requires that composite material surface must have certain finish.And carbon fibre composite
In forming process, due to resin layer content uniformity, solidification of hot-press tank uniformity and fiber grain, lead to composite wood
The defects of jumping silk and fiber grain there are pinprick, bubble, fiber with mould contact surface after material solidification, directly carries out metallization work
It is discontinuous to may cause metal layer, and each position finish of panel is inconsistent, and then influences antenna surface absorptivity-emissivity ratio.
Summary of the invention
For the defects in the prior art, the object of the present invention is to provide a kind of raising composite material antenna reflective face surfaces
The method of finish.
A kind of method of the raising composite material antenna reflective face surface smoothness provided according to the present invention, comprising:
S1, composite material antenna reflective face is roughened, does not allow to destroy antenna during roughening treatment
The type face precision of reflecting surface；
S2, it coats release agent one time, dries rear spare in the die surface for manufacturing antenna reflective face；
S3, it after preparing normal-temperature curing epoxy resin according to the ratio of resin and curing agent, is put into vacuum drying oven processing and takes out
It is vacuum-treated；
S4, the epoxy resin of vacuumize process is coated uniformly on to antenna reflective face surface, room temperature, until asphalt mixtures modified by epoxy resin
Rouge solidification reaches B-stage, the directional swing antenna reflective face in placement process；
S5, the epoxy resin for being up to B-stage and aerial panel are put into togerther in mold, and prepare vacuum bag, and be put into
It vacuumizes heating in autoclave to suppress, heating temperature is 40 DEG C~50 DEG C, solid using room temperature between pressure 0.3MPa~0.7MPa
The flowability of resin after change resin B stepwise heating, the displacement between aerial panel and mold after suppressing, reduce
Mold temperature demoulds afterwards for 24 hours to normal temperature cure.
Preferably, Antenna Reflector Based on Carbon Fibre Composites type face precision before forming resin-rich layer has met using need
It asks.
Preferably, the resin-rich layer is normal temperature solidified epoxy-resin systems.
Preferably, epoxy resin resin-rich layer is applied between mold and aerial panel, and the finish of mold is better than most
Whole antenna reflective face requirement.
Preferably, the aerial panel inside panel is roughened before rich resinification.
Compared with prior art, the present invention have it is following the utility model has the advantages that
The present invention improves the consistency of composite surface finish using preset surface resin-rich layer, is metallization process
And the adjusting of absorptivity-emissivity ratio provides foundation.
Specific embodiment
The present invention is described in detail combined with specific embodiments below.Following embodiment will be helpful to the technology of this field
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the ordinary skill of this field
For personnel, without departing from the inventive concept of the premise, several changes and improvements can also be made.These belong to the present invention
Protection scope.
A kind of method improving Antenna Reflector Based on Carbon Fibre Composites surface smoothness provided by the invention, including with carbon
Inside panel and exterior skin made of fibrous composite and the honeycomb interlayer being arranged between inside panel and exterior skin, Inner Mongol epidermis
The preset one layer of resin-rich layer in face, the resin-rich layer are mainly made of epoxy resin.Specifically, the invention firstly uses certain thick
Roughening process is roughened high-precision composite material antenna reflective face surface, and roughening does not allow to destroy day
The type face precision in line reflection face；Then mirror surface in the roughened uniformly coats one layer of normal temperature solidified epoxy resin
(using spraying or manual application all can), room temperature stand until resin reach B-stage；By the die surface of contoured beam antenna reflecting surface
Release agent is coated, the high-precision antenna reflector of resin layer is put into mold after drying and prepares vacuum bag and is risen in autoclave
Temperature suppresses (temperature is 50 DEG C, and pressure is 0.3MPa~0.7MPa), utilizes the finish of mold itself and the excipient of epoxy resin
Property obtain the antenna reflective face of best bright finish, provided for the metallization of subsequent antenna reflecting surface and accurate adjusting Surface absorption transmitting ratio
Basis.
More specifically, resin layer is epoxy resin.Epoxy resin can solidify at normal temperature.Epoxy resin and composite wood
Resin matrix need to have certain binding force in material.Molding resin-rich layer must be implemented on roughened high-precision reflecting surface.Mould
The finish of tool must be better than the final finish demand of reflecting surface.Before forming resin-rich layer, it is necessary to take out to resin layer true
Vacancy reason, removes the bubble inside resin layer；Resin-rich layer is after composite material surface implementation, it is necessary to stand and arrive B-stage, into one
Step eliminates the bubble generated in resin；Resin layer in conjunction with mold after must be put into autoclave heating at once and suppress, convenient for tree
Rouge layer VISCOUS FLOW, and prevent mold and product faying face from generating bubble
Below in conjunction with further preference, the present invention is described in further details.
