The driving role of the research and development of new aerospace vehicles
With the iteration and upgrading of global aerospace technology, the demand for lightweight, high temperature resistance and functional integration of new aircraft continues to rise. With its unique molecular structure, silicone materials have become a key support for promoting technological breakthroughs. In terms of lightweight, modified silicone composites increase the specific strength by 200% through nanostructure reinforcements, while the density is only 1/3 of that of metals, which can significantly reduce the weight of aircraft structures. In the field of high temperature resistance, silicone-based sealing materials have achieved continuous and stable operation for 36 hours at a high temperature of 500°C, and their anti-enclosed degradation performance enables engine components to maintain sealing under extreme working conditions. In terms of functional integration, conductive silicone sealants achieve ultra-high conductivity with a volume resistivity of less than 0.01Ω·cm by adding silver powder or silver-plated fillers, and can effectively reduce electromagnetic interference with radar wave absorption function. In the future, with the development of the sixth-generation fighter, hypersonic aircraft and space exploration equipment, the application proportion of silicone materials in thermal protection systems, stealth coatings and intelligent structural parts will continue to increase.

Performance breakthrough direction for extreme environment applications
Aerospace vehicles operate in extreme environments such as space radiation, high and low temperature alternation and chemical corrosion, which places strict requirements on the stability of materials. Organic silicon materials achieve performance breakthroughs through molecular design: radiation-resistant organic silicon composite materials can remain unburned for 15 minutes under a 1093℃ flame, and their carbonized layer structure can effectively block thermal radiation; fuel-resistant fluorosilicone sealants introduce methyl trifluoropropyl chain links to maintain chemical inertness to aviation kerosene in the temperature range of -55℃ to 230℃, and are suitable for integral fuel tank sealing; electromagnetic shielding organic silicon foam materials have a shielding effectiveness of 80dB in the 10GHz frequency band, and are also lightweight and easy to construct. Frontier research is focusing on the development of self-healing organic silicon coatings, whose microencapsulated repair agents can be automatically released at cracks to extend the service life of components.

Industrial path of green manufacturing and sustainable development
Faced with the urgent need for environmentally friendly materials in the aerospace field, the green production of organic silicon materials has become a technical focus. Through catalytic process optimization, volatile organic compound emissions in the silicone rubber preparation process are reduced by 40%, while the by-products of the hydrolysis and condensation reactions are recycled. In the field of recycling, thermoplastic silicone elastomers can be processed secondary through hot pressing, and their recycling rate is over 90%. In the future, the research and development of bio-based silicone monomers will further reduce dependence on fossil resources and drive the industry towards the goal of carbon neutrality.
