RECYCLABLE THERMOFORMED STRUCTURAL PANEL MADE OF SINGLE POLYMER TYPE IN ADHERED MULTI-LAYERS OF NON-WOVEN FABRIC

摘要

Recyclable structural panel (18), e.g. auto heat-liner, made of temperature/pressure bonded laminate of foundation (10), bonding (12) and facing (14) layers all of non-woven fabric of a single polymer species of the component fibers, the fiber of the intermediate layer being of a lower melting point range compared to at least a majority of fibers of the other layers to form a remelted film in the course of the bonding process.
