Abstract
A fan track liner for a fan containment arrangement for a gas turbine includes a cellular impact structure and a supporting sub-laminate integrally formed with each other from fibre-reinforced material. The fan track liner further includes a ballistic barrier comprising a woven reinforcing fibre ply and a layer of reinforcing fibre felt. There is also disclosed an associated fan containment arrangement and a method of manufacturing a fan track liner.
Claims12
An apparatus comprising:
- a fan track liner for a fan containment arrangement for a gas turbine engine, the fan track liner comprising a cellular impact structure and a supporting sub-laminate integrally formed with each other from a fibre-reinforced polymer material,
- wherein the fan track liner further comprises a ballistic barrier comprising a woven reinforcing fibre ply and a layer of reinforcing fibre felt.
A method of manufacturing a fan track liner for a fan containment arrangement for a gas turbine engine, the method comprising:
- depositing fibre-reinforced polymer material to form a first portion of the fan track liner or a fan track liner preform;
- forming a ballistic barrier layer on the first portion of the fan track liner or the fan track liner preform by applying a woven reinforcing fibre ply and a layer of reinforcing fibre felt;
- and
- depositing fibre-reinforced polymer material onto and around the ballistic barrier layer to form a second portion of the fan track liner or the fan track liner preform, thereby encapsulating the ballistic barrier layer between the first and second portions of the fan track liner or the fan track liner preform.
