Panels with antinoise and antifragmentation properties on the basis of acrylic glass, process for their preparation and use thereof

摘要

The present invention relates to panels on the basis of polymethylmethacrylate (so-called acrylic glass) with embedded reinforcing polymer monofilament fibres in the form of a three-dimensional fibre entanglement, wherein the reinforcing polymer fibres are embedded into the polymethylmethacrylate matrix in such a manner that they are oriented in all directions and distributed apparently uniformly in all directions, so that the fibres are apparently uniformly distributed essentially throughout the entire cross-section of the panel i.e. throughout its entire volume. Particularly, the present invention relates to polymethylmethacrylate panels with included polyamide fibers in the form of a three-dimensional fibre entanglement. The present invention also relates to a process for manufacturing such panels and to the use thereof, especially as antinoise elements along roads with good antifragmentation properties.
