Abstract

The invention discloses a lightened high-temperature and high-pressure composite cylinder and a manufacturing method of the lightened high-temperature and high-pressure composite cylinder. The composite cylinder comprises filler necks and a bottle body, wherein the filler necks are arranged at two ends of the composite cylinder, the bottle body is arranged in the middle of the bottle body and sequentially comprises an ablation-resistant thin-wall metal liner, a ceramic tile thermal-insulation layer, a rubber thermal-insulation layer and a winding layer from inside to outside, and the winding layer is made of carbon-fiber-reinforced-resin-base composite materials. The manufacturing method comprises the following steps: (1) spheroid forming, (2) sand core forming, (3) metal liner forming, (4) thermal-insulation layer forming, (5) winding layer forming and (6) demolding and sand core dissolving. The composite cylinder has the advantages that a thin-wall metal material is taken as a liner, the light and high-temperature-resistant ceramic tile-rubber composite thermal-insulation layer is creatively utilized, and a ceramic tile in a quartz-fiber porous skeleton structure is taken as a main thermal-insulation material and is externally supplemented with a layer of rubber to be taken as an airtight layer, so that the weight of the thermal-insulation layer is reduced by 70-80% when the long-time high temperature resistance and ablation resistance are guaranteed, the working efficiency of an engine is substantially increased, and the requirements of a power system for the high total impulse and the high thrust are met.

Description

technical field [0001] The invention relates to an aircraft solid attitude control power system equipment forming technology, in particular to a lightweight high-temperature and high-pressure composite gas cylinder and a manufacturing method thereof. Background technique [0002] Composite gas cylinder, that is: solid engine shell, is a container for storing high-temperature and high-pressure gas flow within a predetermined period of time in the solid attitude and orbit control power system. Scouring, therefore, requires that the gas cylinder must have high air tightness, temperature resistance and ablation resistance. In order to ensure that the existing high-temperature and high-pressure gas cylinders can be used safely in the working environment, the thickness of the gas cylinders is generally thick, which makes the negative weight of the gas cylinders too large. Demand for high total stroke and high thrust. Contents of the invention [0003] The object of the present...
