Abstract
A composite material sheet or panel is obtained by extruding a mixture composed of at least one thermoplastic material, particularly of the polyolefin family, and of mineral fibers having predetermined dimensional characteristics (diameter and length). The extrusion process is performed with parameters sufficient to generate in the sheet a three-dimensional structure embedded in the thermoplastic material.
