Abstract
The utility model provides a reflecting mirror of a super light space camera, which is composed of a basis layer (1), a surface layer (2) and a coating layer (3), wherein the basis layer (1) is a main body of the reflecting mirror and is formed by compounding multilayer tridimensional braiding carbon filament or aromatic polyamide fiber which is taken as a skeleton and a thermoplasticity resin composite layer which is filled between the layers and the gaps of the skeletons, and the thickness can be determined according to the design requirement. The skeleton uses an integral structure and also uses the compounding and the overlapping of multilayer skeletons, and the porosity is between 40 percent and 60 percent. The basis layer (1) can use carbon filament and glass microsphere reinforced thermoplasticity resin composite materials and is formed by one step through injection; the surface layer (2) uses resin layer with good optics processing performance and is formed by the molding method of coating solution or melting, the shape of the reflecting surface which is needed is formed after the optics processing and the resin layer can uses ester class polymer or amine class polymer. The coating layer (3) is a metal coating layer with high adhesiveness on the surface of the coating layer after the surface layer (2) is processed, and the good reflecting performance is also provided.
Description
Technical field
The utility model discloses a kind of ultra lightweighting space camera catoptron.
Background technology
Space camera is meant the optical system of working in outer space or space, catoptron is the critical component of space camera, and it is restricting the sensitivity and the resolution of space camera.Traditional space camera catoptron generally adopts the fused quartz manufacturing, and this is because fused quartz has very outstanding optics processability and dimensional stability; But the excessive application that has limited in heavy caliber space camera catoptron of its density.For weight reduction, DeCaprio (US 5076700) has designed the honeycomb in the fused quartz basal body of reflector, has made catoptron weight saving about 70%; Fletcher (US 4035065) discloses a kind of foamglass sandwich construction that adopts in basal body of reflector; Davis (US 176588) discloses and adopted ceramic honeycomb sandwich construction in basal body of reflector; People such as fourth Fujian (CN 1335520A, CN 2501068Y) disclose a kind of multi-layer compound structure that adopts honeycomb interlayer in basal body of reflector; These lightweights that are designed to the space camera catoptron provide multiple possible approach.
Summary of the invention
The purpose of this utility model is a kind of ultra lightweighting space camera catoptron of design, and this catoptron is made up of basic unit 1, surface layer 2 and coating 3:
Catoptron requires to have extremely low thermal expansivity, the excellent surface optics reflecting properties and the light weight of trying one's best.The fused quartz material can provide very low thermal expansivity for catoptron, but proportion is excessive; Adopt honeycomb in fused quartz after, the catoptron overall weight alleviates to some extent, but the homogeneity of honeycomb is difficult to control, must influence the stability of catoptron expanded by heating, so the single layer structure catoptron has bigger limitation.The utility model is in order to overcome the limitation of single layer structure catoptron, designed sandwich construction, adopting stereo weaving carbon fiber or aramid fiber is skeleton, for catoptron provides the low bulk performance, adopt the good resin of optics processability to make surface layer, for having final good optical surface, catoptron provides possibility, so can realize the design of catoptron overall performance is made it to reach optimum performance by the material and the structure of control different structure layer.
The technical solution of the utility model is described below in conjunction with the accompanying drawings:
Accompanying drawing 1 is the synoptic diagram of ultra lightweighting space camera catoptron
Among the figure 1, basic unit 2, surface layer 3, coating
Basic unit (1) is the main body of catoptron, it is to be full of the thermoplastic resin composite bed through being composited in skeleton, interlayer and the skeleton gap that system adopts with layer stereo weaving carbon fiber or aramid fiber, its thickness can be decided according to designing requirement, skeleton can adopt one-piece construction, also can adopt the stack of multilayer skeleton compound, porosity is 40～60%; Basic unit 1 also can adopt the thermoplas tic resin composite of carbon fiber and glass microballoon enhancing through the injection moulding one-shot forming; Surface layer 2 adopts the good resin bed of optics processability to apply or the moulding of melt molding method by solution, forms the reflecting surface type that needs after optics processing; This layer resin can adopt ester class or amine polymer; Coating 3 be after surface layer 2 machines in the above the high tack coat of metal so that good reflecting properties to be provided.
Characteristics of the present utility model are that the speculum skeleton adopts high strength, high-modulus, low-density Carbon fiber or aramid fiber form by stereo weaving, and basic unit's matrix and surface layer all adopt high score Sub-composite, the interlayer compatibility is good, light specific gravity, linear thermal coefficient of expansion is low, so can make anti-Penetrate mirror when guaranteeing desirable face type, have the feature of ultra lightweighting.
Claims (2)
1, a kind of ultra lightweighting space camera catoptron, this catoptron is made up of basic unit (1), surface layer (2) and coating (3), it is characterized in that, basic unit (1) adopt layer stereo weaving carbon fiber or aramid fiber be full of in skeleton, interlayer and the skeleton gap that thermoplastic resin composite bed, thickness can decide according to designing requirement, can to adopt one-piece construction also can adopt superpose compound, porosity of multilayer skeleton be 40～60% to skeleton; Surface layer (2) adopts good ester class of optics processability or amine polymer resin to apply or the moulding of melt molding method by solution; Coating (3) adopts the high tack coat of metal.
2, ultra lightweighting space camera catoptron as claimed in claim 1 is characterized in that, described basic unit (1) also can adopt the thermoplas tic resin composite of carbon fiber and glass microballoon enhancing through the injection moulding one-shot forming.
