Abstract
The present invention relates to method of manufacturing an aircraft interior panel comprising a core sandwiched between first and second skins, wherein both of the first and second skins are formed from natural fibers containing non-halogenated fire-retardant and set within an inorganic thermoset resin, thereby forming a fire-resistant sustainable aircraft interior panel. The method comprises impregnating the natural fibers with non-halogenated fire retardant and an inorganic thermoset resin, and laying up the resin-impregnated natural fibers to sandwich the core. This stack is then cured by raising the temperature of the stack sufficient to initiate curing but without reaching the boiling point of water in the stack, holding the stack at that first temperature before raising the temperature again to reach the boiling point of water in the stack, before cooling the stack.
