Multi-layer insulation (MLI) is thermal insulation composed of multiple layers of thin sheets and is often used on spacecraft and cryogenics. Also referred to as superinsulation, [ 1 ] MLI is one of the main items of the spacecraft thermal design , primarily intended to reduce heat loss by thermal radiation .
Insulation is a barrier material to resist/reduce substance (water, vapor, etc. ) /energy (sound, heat, electric, etc.) to transfer from one side to another. Heat/ Thermal Insulation is a barrier material to resist / block / reflect the heat energy (either one or more of the Conduction, Convection or Radiation) to transfer from one side to another.
The key to a reusable shield against this type of heating is very low-density material, similar to how a thermos bottle inhibits convective heat transfer. [ citation needed ] Some high-temperature metal alloys can withstand reentry heat; they simply get hot and re-radiate the absorbed heat.
Insulation to resist conductive heat transfer uses air spaces between fibers, inside foam or plastic bubbles and in building cavities like the attic. This is beneficial in an actively cooled or heated building, but can be a liability in a passively cooled building; adequate provisions for cooling by ventilation or radiation [ 62 ] are needed.
White sands test sample, owned by Thermashield, LLC. Starlite is an intumescent material said to be able to withstand and insulate from extreme heat. It was invented by British hairdresser and amateur chemist Maurice Ward (1933–2011) during the 1970s and 1980s, and received significant publicity after coverage of the material aired in 1990 on the BBC science and technology show Tomorrow's ...
