ABSTRACT:
A composite article includes a plurality of laminates each having structural fibers bonded in a matrix, and an adhesive film disposed between and bonding together adjacent ones of the laminates. In an exemplary embodiment, the laminates and the interleaved adhesive films form a facesheet which is joined to a core for forming an impact resistant fan case impact liner for a gas turbine engine. The impact liner may be integrated with a sound suppression liner.
