High and ultra-high vacuum applications require seals that do not allow leaks. O-rings can break down over time, due to aging and exposure to radiation. Metallic seals can damage sealing surfaces, making replacement of the original seal very difficult.
The ID provides a solution approach for faster chemical processing and carbon functional grading from SiC to MC to provide a tougher carbon and CMC structure.
The solution proposed here is a modified carbon-based tile face that is mechanically combined with an insulative backing. The tile face is based on a material architecture to minimize weight and thermal conductivity while maximizing thermal stability.
This technology aims to provide and integrated and oxidation resistant cladding or coating onto carbon-based composites in seconds.
The technology describes an electron beam in a storage ring as a quantum computer.
Silicon nitride fiber is a critical material mainly used in the aerospace industry but has many applications. This fiber is prized for its properties, as it is transparent to electromagnetic radiation but allows signals to go through it.
