• Geopolymer Composites: A Ceramics Alternative to Polymer Matrices About.com article "...Geopolymer composites have been investigated and developed for a variety of applications. A five-year program funded by the Federal Aviation Association at Rutgers University, in conjunction with France's Geopolymer Institute, looked at developing low-cost, environmentally-friendly, fire resistant matrix materials for use in aircraft composites and cabin interior applications. The goal of the program was to eliminate cabin fire as cause of death in aircraft accidents. Unlike conventional polymer composites, carbon-fiber reinforced geopolymer composites did not ignite, burn, or release any smoke even after extended heat flux. Therefore, they are suitable as aircraft cabin materials for cargo liners, ceiling, floor panels, partitions and sidewalls, stowage bins, and wire insulation.

In France, a fire-resistant geopolymer-encased electronic flight recorder has been patented by S.F.I.M. and jets are also being equipped with a highly advanced fireproof air filter from Sofiltra-Camfil. For Northtrop Aviation, a geopolymer composite tooling prototype (self-heated carbon/SiC/geopolymer composite) was used in the fabrication of a carbon composite designed for a new US Airforce bomber. Formula 1 racing cars have also been built with carbon/geopolymer composites as thermal shields in the exhaust system, replacing titanium...."

• Alkaline Cements and Concretes, Properties of Geopolymer cements Technical abstract by Joseph Davidovits "...The behaviour of geopolymeric cements is similar to that of zeolites and feldspathoids; they immobilize hazardous materials within the geopolymeric matrix, and act as a binder to convert semi-solid wastes into adhesive solids. Their unique properties which include high early strength, low shrinkage, freeze-thaw resistance, sulphate resistance and corrosion resistance, make them ideal for long term containment in surface disposal facilities...."
