Fire resistant matrix materials for use in aircraft composites and cabin interior applications

The Federal Aviation Administration (F.A.A.), USA, has recently initiated a research program to develop low-cost, environmentally-friendly, fire resistant matrix materials for use in aircraft composites and cabin interior applications. The flammability requirement for new materials is that they withstand a [...]

There is a clear relationship between water ratio and mechanical properties. The water is our carrier. Polycondensation happens between compounds that are soluble in water. It is the water content which determines the density of the matrix. After polycondensation, the excess of water which is not tied to the structure in the form of -OH [...]

The atomic ratio Si:Al in the poly(sialate) structure determines the properties and application fields. A low ratio Si:Al (1,2,3) initiates a 3D-Network that is very rigid. A high ratio Si:Al, higher than 15, provides polymeric character to the geopolymeric material. One third of Davidovits’ book, GEOPOLYMER Chemistry & Applications, is dedicated to applications. See the [...]

Geopolymeric binders, used either with rock aggregates to produce rock-concretes or with carbon fibers to produce non-flammable composites, have a variety of important industrial uses.
The same geosynthesis that produces geopolymeric rock-cements is used industrially for making binders for advanced composite materials. Updated research is presented in Davidovits’ book, Geopolymer Chemistry & Applications, Chapters 8, [...]
