ABSTRACT:
In a motor vehicle body, a rigidly fastened roof (10) of composite material rests upon a frame rigid with the body as a complete prefabricated component. The roof (10) is formed as a composite component which is produced in a hot pressing process and is formed by an air-tight and rain-proof outer layer (11), an intermediate structural layer (12) and a semi-rigid, porous inner layer (13) with a padding and/or decorative layer (14). The continuous edge around the roof is shaped by hot pressing deformation of all the layers to form joining flange areas of different cross-sections which are joined to the areas of the frame rigid with the body by a permanently resilient, vibration-absorbing adhesive bead and by additional screw connections at strategic points.
