More Information
Summary:The invention relates to a sound protection screen (1) intended to be mounted under a motor vehicle, comprising a thermo-compressed shell (2) based on structural fibres bonded together by a heat-activated bonding agent and provided with an outer face (3) covered with a protective fibrous layer (4) consisting of: between 50% and 70% of bi-component fibres comprising a core with a high melting point and a sheath with a lower melting point; between 30% and 50% of polypropylene fibres, so as to provide an apolar component conducive to low ice adhesion, the layer having been melted at a temperature higher than the melting temperature of the sheath and the polypropylene, and lower than that of the core, so as to provide a smooth surface state and to minimise the mechanical adhesion of the ice.
