Abstract
Abstract A THERMOSETTABLE BUT TEMPORARILY THE THERMOPLASTIC ACRYLIC FILM IS CAST UPON A LAYER OF THERMOPLASTIC FILM SUCH AS POLYPROPYLENE. A LAYER OF UNSPUN AND UNBONDED TEXTILELENGTH FIBERS IS SUPERIMPOSED UPON THE ACRYLIC FILM, AND THE MULTI-PLY ASSEMBLY IS SUBJECTED TO HEAT AND PRESSURE SUFFICIENT TO CAUSE THE FILMS TO FLOW AROUND AND ENCAPSULATE AT LEAST 80% OF THE FIBERS, WHICH REMAIN IN DISCONTINUOUS PHASE. UNLIKE ORDINARY LAMINATES, SUCH PRODUCTS ARE CHARACTERIZED BY A SINGLE INFLECTION POINT IN THE STRESS-STRAIN CURVE, AND ARE SUITABLE FOR BASES FOR ADHESIVE TAPES.
