Composite heat shield for spacecraft reentry body

Abstract

The invention discloses a composite heat-proof layer scheme for a spacecraft reentry body, belonging to the technical field of spacecraft heat protection. The purpose of the utility model is to provide a novel composite structure heat-proof layer capable of coping with severe heat environment. The technical scheme is as follows: a composite heat-proof layer for a spacecraft reentry body, which is characterized in that it is composed of a heat-insulating layer and an ablation layer, and the ablation layer is formed by winding fiber reinforced material impregnated with phenolic resin. A method for forming a heat-resistant layer of a composite structure, which is characterized in that it includes the following steps: forming the heat-insulating layer, compounding the formed heat-insulating layer with an ablation layer, curing the formed composite-structured heat-resistant layer under high temperature pressure, and machining forming. It achieves the purpose of reducing the thermal conductivity and temperature conductivity of the heat-resistant component. The component is light in weight and has excellent performance, which can meet the requirements for improving the heat-resistant performance of various spacecraft reentry bodies at present, and is suitable for industrial production.

AI Technical Summary

Benefits of technology

This patented technology describes an alternative way to make better ways to prevent fires when entering spacesuits during flight operations. By incorporating certain special features or compositions within these layers, they improve their ability to resist fire damage without compromising its effectiveness at other temperatures. These techniques help protect against flammable liquids such as fuel oil and gasoline inside the aircraft's cabin interior. Additionally, there may include different methods used to create the necessary ingredients needed for effective manufacturing processes like injection molded thermosets (RIM)). Overall, this innovative design helps achieve desired results through improving the overall properties of the air conditioner system itself.

Problems solved by technology

This patented describes different ways that space craft parts are protected from damage caused during rapid changes between atmospheric conditions or after being returned into an airspace environment without losing their effectiveness over long periods of times. One method uses special materials called fibrofibreglass compositions made up of layers of silica sandwiching one another. These techniques aim to improve durability while still maintaining good electrical conductivity properties.
