Abstract
There is described a sound-insulating power vehicle part which includes a shaped outer sheet and an acoustically effective inside packing which together form an inherently stable lightweight composite part. To obtain this, a thermosetting plastic is used for the outer sheet while the inside packing is formed of a fiber-resin fleece, which is only slightly compacted in an acoustically effective main area and is closely compacted in its stabilizing areas.
