Abstract
The present invention relates to acoustical panels. As to provide a cabin panel to be made as simple as possible and with optimized acoustical properties, an acoustical cabin panel () is provided that comprises a first () and a second layer () which are spaced apart from each other by an intermediate layer () and altogether with a plurality of reinforcement elements () form a core composite component (). Furthermore, the panel comprises at least one intermediate layer () made of a core material () which is arranged in the intermediate layer. The reinforcement elements extend from the first to the second layer through the at least one intermediate film and are tension and pressure resilient in a finished state of the panel. The reinforcement elements can be at least partially infiltrated with a curable matrix material and at least one prepreg () soaked with matrix material is provided in the first and/or second layer. Thereby, the reinforcement elements to be infiltrated with matrix material are connected to the prepreg.
