Improved furan-phenol resin with decreased flammability, pre-impregnagted fiber reinforced composite and application thereof

摘要

The present invention relates to an improved phenolic furan resin composition with reduced flammability and to a pre-impregnated fiber-reinforced composite material. The invention also relates to the use of pre-impregnated fiber-reinforced composite material as a chimney liner. The object of the invention was to develop a composite system with improved heat resistance, which means that, with its reduced flammability, it not only prevents the propagation of possible fire, but also does not damage and maintains its mechanical properties at a sufficiently high temperature. In the composition of the present invention, the use of additives and fillers, also known as components such as glass fiber, glass beads, boron compounds, for other composite materials, for use as flame retardants and relative proportions of the sodium methasilicates (especially its pen- tahydrate) and melamine derivatives according to the invention increases the flame-retardant effect significantly.
