Zusammenfassung:	Sandwich construction for automotive applications consisting of a honeycomb core (2) covered at both sides with a skin layer (1a, 1b) whereby each of the skin layers consist of a web of random laid melt spun polyester bicomponent filaments (4), which were cross-lapped (6, 7) and needled (8) to form a nonwoven mat (9) and which was compressed during moulding of the sandwich construction to form a compact skin layer with bonded filaments, which is bonded to the core. L'invention porte sur une construction en sandwich pour des applications à l'automobile, ladite construction comprenant un coeur en nid d'abeilles (2) recouvert des deux côtés par une couche de peau (1a, 1b), ce par quoi chacune des couches de peau est constituée par un film de filaments bicomposants en polyester filés par fusion déposés de façon aléatoire (4), qui ont été superposés transversalement (6, 7) et aiguilletés (8) de façon à former un mat non tissé (9), et qui a été comprimé durant le moulage de la construction en sandwich afin de former une couche de peau compacte avec des filaments liés, laquelle est liée au coeur.
