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.
Claims8
A fan case liner for a gas turbine engine comprising:
- an integral facesheet including a plurality of laminates each having structural fibers bonded in a matrix, and a toughened adhesive film disposed between and bonding together adjacent ones of said laminates;
- a first structural support core, and another adhesive film disposed between and bonding together said facesheet and said first core;
- a second structural support core;
- a first septum disposed between said first and second cores;
- additional adhesive films disposed between and bonding together said first septum and said first core, and said first septum and said second core;
- and
- wherein said first core has a first compressive strength, and said second core has a second compressive strength less than said first compressive strength.
