Latest Patents

**Composite plate and method of draining a composite plate.** This invention describes a composite plate with two cover layers and an intervening core containing cells separated by walls. A draining layer in the first cover layer at least partially covers the cells, helping resist liquid ingress and prevent liquid from accumulating.

**Sound-absorbing element for transport means, in particular for aircraft.** This invention concerns an air-permeable sound absorption element made from sound-absorbing panels arranged on a perforated base panel. Each panel is framed, and transition profiles are provided along at least part of the frames to reduce fatigue fractures caused by changes in rigidity between the frames and the base panel.
