Abstract: The present invention relates to a polymeric adhesive matrix and to a process for producing such a polymeric adhesive matrix, wherein the matrix comprises either: 1) a substantially uniform thickness nonwoven web comprising Nylon 12 or Nylon 11 polymer, or blends thereof, with up to 40 weight percent of another compatible thermoplastic polymeric material; or 2) a substantially uniform thickness fibrous or non-fibrous matrix comprising an amine-terminated low moisture absorbing polyamide, preferably an amine-terminated Nylon 12 or amine-terminated Nylon 11 polymer, or blends thereof, with up to 40 weight percent of another compatible thermoplastic polymeric material. The subject invention also relates to a multi-layer composite laminate comprising at least one layer of the polymeric adhesive matrix of the present invention positioned between a plurality of reinforcing fibrous layers impregnated with a binder resin and to a process for producing such a multi-layer composite laminate.
