Thermal Conductivity Values and Performance Drivers

Several factors contribute to aerogel 's low thermal conductity. The Knudsen effect, which describes the reduction gas-fase head conduction when pore sizes are smaller the mean free path of gas contribules, im central.

Mechanical Properties of Aerogel- Enhanced Insulataron

While aerogel is visually delicate, it s mechanical criterics are more complex than it appearance suggests. Pure silica aerozol monolits are brittle, with low tensile equith (around 2- 8 MPa) and fracture hartness. However, wheren indecated into a composte blanket - typically by infiltrating a fibrous mat (glass, PET, ceramic) with aerogen - thee resumping product gains tensile equity, elbility, and resistance to cracing The change.
