A family of inorganic matrices, called geopolymers, is being investigated for use in fire-proof composites. Initial mechanical testing has yielded promising results. Further mechanical testing is currently being conducted under a Federal Aviation Administration (F.A.A.) initiative to develop fire safe materials for aircraft interiors. Strong evidence indicates that the tensile strain capacity of the matrix controls many of the composite's properties. This paper presents the results of an experimental investigation of the strain capacity of geopolymers. A cantilever beam with a thin film of geopolymer bonded to the tensile face was used to induce predetermined tensile strains in the film. Effects of matrix chemistry and fiber inclusions on the tensile strain capacity of geopolymers are presented. In addition to strain capacity, values for saturation crack spacing are also presented.
