A radial rib with film belongs to the technical field of radial rib antenna, which solves the problem that the existing rib is made of carbon fiber board as a whole, which is heavy and not easy to fold and fold. It includes carbon fiber board and double-layer polyimide film, the carbon fiber plate is fixedly bonded to the double-layer polyimide film, the carbon fiber plate is aligned with the lower edge of the double-layer polyimide film, and the joint surface of the carbon fiber plate and the double-layer polyimide film is integrally bonded, and the carbon fiber plate A plurality of triangular fins are arranged on the upper side of the board, and a suspension hole is provided at each triangular fin, and a plurality of suspension holes are arranged on the upper edge of the double-layer polyimide film. A reinforcing film is arranged around the plurality of suspension cable holes on the film. The invention is used for the radial rib antenna to ensure the accuracy of the reflection surface.
Description
Technical field
The invention belongs to radial rib antenna technical field, be specifically related to a kind of band film radial rib.
Background technology
The floor of the inflating expanded antenna of radial rib plays the effect of guaranteeing reflector precision, and the whole carbon fiber board that adopts of existing floor is made, and weight is large, and is not easy to draw in folding.
Summary of the invention
The object of the invention is to make in order to solve the whole carbon fiber board that adopts of existing floor, weight is large, and is not easy to draw folding problem in, and a kind of band film radial rib is provided, and its technical scheme is as follows:
A kind of band film radial rib, it comprises carbon fiber board and the sub-film of double-deck polyamides, the sub-film fixed bonding of described carbon fiber board and double-deck polyamides, carbon fiber board aligns with the lower limb of the sub-film of double-deck polyamides, the abutted surface integrated bond of the sub-film of carbon fiber board and double-deck polyamides, at carbon fiber board upside, be provided with a plurality of triangle fin keels, and be provided with suspension cable hole at each triangle fin keel place, on the sub-film of double-deck polyamides, along top edge, be provided with a plurality of suspension cables hole, a plurality of suspension cables hole on the sub-film of double-deck polyamides is provided with strengthening membrane around.
Beneficial effect of the present invention is: changed the whole structure that adopts carbon fiber board of existing floor, use the sub-film of double-deck polyamides to replace part carbon fiber board, weight is obviously reduced, and be easy to draw in folding, volume after folding is little, on the sub-film of double-deck polyamides with on triangle fin keel, be provided with suspension cable hole, after use hoist cable is connected with mast, can guarantee floor precision and stability.
accompanying drawing explanation:
Fig. 1 is structural representation of the present invention;
embodiment:
With reference to Fig. 1, a kind of band film radial rib, it comprises carbon fiber board 1 and the sub-film 2 of double-deck polyamides, described carbon fiber board 1 and sub-film 2 fixed bondings of double-deck polyamides, carbon fiber board 1 aligns with the lower limb of the sub-film 2 of double-deck polyamides, the abutted surface integrated bond of carbon fiber board 1 and the sub-film 2 of double-deck polyamides, at carbon fiber board 1 upside, be provided with a plurality of triangle fin keel 1-1, and be provided with suspension cable hole 3 at each triangle fin keel 1-1 place, on the sub-film 2 of double-deck polyamides, along top edge, be provided with a plurality of suspension cables hole 3, a plurality of suspension cables hole 3 on the sub-film 2 of double-deck polyamides is provided with strengthening membrane 3-1 around.
Using method and the principle of invention: it is bonding that the materials such as aramid fiber cloth and central dram axostylus axostyle and crisp bar can be passed through in head and the tail two ends, the part of carbon fiber board 1 can be bonding to refer to the mode of inserting and central dram axostylus axostyle and crisp bar by aramid fiber cloth, and be connected with crisp bar by hoist cable at 3 places, suspension cable hole, primary load bearing hoist cable is connected with the suspension cable hole 3 on carbon fiber board 1, and the suspension cable hole 3 from the sub-film 2 of messenger wire and double-deck polyamides is connected; It is high that the sub-film 2 of double-deck polyamides has hot strength, is difficult for occurring plastic deformation, and high temperature resistant, radiation hardness, resistance to chemical attack and electrical insulation capability are high, and lightweight, have alleviated greatly floor weight, are also easy to draw in folding.Mast, as a kind of force transferring part, can provide uniform radial development power, and this radial development power can be guaranteed this precision with film rib and stability.
