Claims15
A method of manufacturing a fan track liner or a fan track liner preform for a fan containment arrangement for a gas turbine engine, the method comprising:
- depositing, by an additive manufacturing apparatus, fibre-reinforced polymer material onto a rotating mandrel to form a cellular impact structure and a supporting sub-laminate integrated with one another.
A method of manufacturing a fan track liner or a fan track liner preform for a fan containment arrangement for a gas turbine engine, the method comprising:
- depositing, by an additive manufacturing apparatus, fibre-reinforced polymer material onto an inboard surface of a fan containment casing or a fan containment casing preform, to form a cellular impact structure and a supporting sub-laminate integrated with one another.
A non-transitory computer-readable medium comprising computer-readable instructions for manufacturing a fan track liner or a fan track liner preform, wherein the instructions, when executed by a processor in operative association with an additive manufacturing apparatus, are configured to cause the additive manufacturing apparatus to:
- deposit fibre-reinforced polymer material onto (i) a rotating mandrel or (ii) an inboard surface of a fan containment casing or a fan containment casing preform, to form a cellular impact structure and a supporting sub-laminate integrated with one another.
