AI Technical Summary
The composite materials used in existing aerospace components in high-temperature environments have insufficient temperature resistance due to the limitations of epoxy resin, and are susceptible to ice accumulation and corrosion, leading to performance degradation and safety hazards.
A resin composition consisting of a multifunctional cyanate, a phenol-terminated modified PDMS oligomer, and a catalyst is used to form a resin blend for preparing a high-temperature corrosion-resistant and ice-repellent composite material. The composite material with a high glass transition temperature is formed by curing.
This achievement ensures material stability and anti-icing properties at high temperatures, reduces the energy consumption of electric heaters, lowers system complexity and weight, and improves the safety and corrosion resistance of aerospace components.
