Beschreibung
Zusammenfassung:	The invention relates to composite elements, which comprise the following layer structure: i) between 2 and 20 mm metal, plastic or wood, ii) between 10 and 300 mm plastic, iii) between 2 and 20 mm metal, plastic or wood. The invention is characterised in that hollow bodies comprising an external diameter of less than 5 mm are contained in layer (ii). L'invention concerne des éléments composites présentant la structure en couches suivante : (i) 2 à 20 mm de métal, de plastique ou de bois ; (ii) 10 à 300 mm de plastique ; (iii) 2 à 20 mm de métal, de plastique ou de bois. L'invention est caractérisée en ce que la couche (ii) comporte des corps creux présentant un diamètre extérieur inférieur à 5 mm.
