In a first aspect, the present disclosure provides a method for making an inorganic thermoset resin, the method comprising: The present disclosure further provides an inorganic thermoset resin obtainable by the method as defined in the first aspect of the disclosure.

Inorganic thermoset resins and methods of making thereof

A method for a curing cycle of an inorganic thermoset resin, the method comprising: (a) adding a hardener in a concentration from 18 to 30% by weight of the resin to said inorganic thermoset resin and (b) curing the resin at a temperature from 110 to 120&#xb0; C. An inorganic thermoset resin, comprising a hardener in a concentration from 18 to 30% by weight of the resin. A vehicle interior panel, comprising a composite comprising a composite matrix of a natural fibre set within an inorganic thermoset resin.

Method for a curing cycle of an inorganic thermoset resin

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.

Method of making fire resistant sustainable aircraft interior panels

The present invention relates to sandwich panels used as aircraft interior parts. In addition to provide a finishing function, the sandwich panels need to have certain mechanical properties and have sufficient fire resistance to retard the spread of fire within the vehicle interior. The present invention provides an aircraft interior panel with skins comprising natural fiber reinforced composites based either on an inorganic thermoset resin or a thermoplastic resin. Such panels provide the required flame and heat resistance, allow easy recycling and disposal, are cheaper and offer significant weight savings over conventional sandwich panels.
