Composite product formed by a slab consisting of an agglomerate of granular and filamentous inorganic materials bound with the use of structural resins which is coupled to a foil of thermoplastic material, and manufactured with a process comprising the steps of: a) preparation of a mixture capable of releasing air, i.e. adapted to be de-aerated; b) association to the mixture of a foil of thermoplastic material having hollow protrusions that are closed at their end facing the mixture; c) transfer of the mixture, enclosed between a sheet or tray and a cover, to a press where it is de-aerated and pressed under vacuum in order to obtain the manufactured product in a raw state; d) application of heat to said raw product, while it still is enclosed between the above mentioned sheet or tray and cover, through a pair of heating planes in order to harden the binding resin. |
