MATERIALES COMPUESTOS REFORZADOS CON CÉRAMICOS AMORFOS PARA APLICACIONES A ALTAS TEMPERATURAS

Abstract

A new hybrid-composite material type for applications on hot surfaces (up to 250°C) was developed, in order to reduce the loss of energy, protect thermal insulation and improve the mechanical resistance and impermeability of the thermal insulation systems. This material is a hybrid-composite with organic polymer matrix mixed with small particles (smaller than 45 μm), like silica and organic fibers. The material may be applied directly on hot surfaces up to 250°C, but for higher temperatures it must be used on thermal insulates which can have lower thickness below 2 cm, saving material costs.
