Description
Summary:[Display omitted] •The number of damage cells in a cork particle influences its elastic properties.•The percentage of damage cell in a cork particle is related to the milling process.•Impact milling mainly affects the elastic properties of particles less than 200μm.•The choice of a milling technology is relevant to preserve the properties of cork. Cork is a natural raw materials used in numerous traditional and innovative applications among which the most famous are cork stoppers, insulation boards, and wall and floor covering. Cork exhibits a relatively homogeneous honeycomb structure composed of polyhedron cells filled with gas, which gives its specific properties such as elasticity or hydrophobic behavior. Mechanical properties of cork have been studied from a long time. However, in many industrial applications cork is increasingly used as granulate (>200μm) or powder (
