Fire resistance inorganic fibres

Heat and fire resistant inorganic and ceramic fibres 261... 

The use of inorganic CERASHELL, a sandwich composed of cellular or foamed straw insulation between two fibre-reinforced high-strength dense materials, surpasses the characteristics of the foam/concrete composite. Pneumatic placement of a non-woven fibre matte as the outer shell results in a low-cost shelter in the first stage prior to placement in later stages of the insulative and structural components. The costs of steel reinforcement and urethane are eliminated, whilst extremely safe buildings of remarkable wind, earthquake, and fire-resistance are produced. 

Each of these major fibre groups has been described elsewhere and so their major features only are presented below. The main groupings of these inherently heat and fire resistant fibres may be divided into the following, namely, the thermosets, the aramids and arimids, the polybenzazoles, the semicarbons and inorganics. Not only are the generic chemistries similar within each grouping, but their properties and potential application suitabilities are similar.
