Name: LI-900 Rigid Tile
Database: NASA Ames Thermal Protection Materials
Category: Silicon-Based Reusable Composites: Rigid Ceramic Tiles
Composition: 100% SiO2
Manufacturer: United Space Alliance (USA)
Technical Readiness Level: 9
Last Modified: 2001-10-01
Description:
- LI-900 is a relatively low density (~9 lbs/cu.ft.) and very low thermal conductivity fibrous insulation material baselined for use on all the shuttle orbiters. It is the primary tile insulation flying almost everywhere on all of the orbiters due to its thermal conductivity, thermal shock resistance and efficiency as a TPS.
