  • Publication number: 20240051272
    Abstract: The present invention relates to a laminate structure comprising a composite adhesive polymeric interlayer (CAPI) comprising at least two layers: (i) a submicron-thick superbonding layer and/or a top adhesive polymeric interlayer (TAPI) and (ii) a bulk adhesive polymeric interlayer (BAPI). If the TAPI is present, it comprises cohesive substantially discrete and/or continuous debonding zones. Such debonding zones are located preferably within the 10% thickness of CAPI from the interface of said CAPI and the glass substrate. These zones allow for a unique combination of modified API-glass debonding, laminate toughness, and laminate durability. Various spatial patterns and densities of debonding are described, as well as the resulting material properties.
