摘要
The invention concerns a sandwich-type material, for use in making cases for instruments, in particular musical instrument and cello case made from same. The composite material (10) consists of a first skin (11), made of metallized acrylonitrile-butadiene-styrene (ABS), a core (12) made of polyvinyl chloride (PVC) foam, and a second skin (13) made of polyester terephthalate (PTEG). The three elements are assembled by bonding, using a single-component heat-activated polyurethane adhesive. The invention is particularly useful for making cases for musical instruments.
