Abstract (en)
[origin: WO2011117699A1] Element made of composite material (10), plant (11) to produce the element (10) and relative method, in which at least a mixing station (13) is provided in which a first plastic component and a second component are mixed together, and at least a station for extrusion and drawing passage through a draw-plate (15), in which said mixed first and second components are extruded and drawn in order to obtain the element (10) having a shaped cross section. The plant (1 1) comprises at least a dispenser member (32) to dispense a chemical expanding agent in powdered form inside the mixture, in order to determine a closed-cell expansion of the material and a porous internal conformation of the element (10). The element (10) thus obtainable is a composite mono-material which comprises an internal core having a form and cross section shaped in a desired manner and a closed-cell porous conformation, made by means of expansion, and an external covering part or surface having a surface hardness and specific weight higher than the value of hardness and specific weight of the internal core.
