Abstract
A turbine engine system comprising a turbine engine component, such as a fan includes a fan casing and a fan blade rotatable within the fan casing. An abradable seal coupled to the fan casing proximate the fan blade. The abradable seal comprising an abradable composite layer including a MAX phase solid and a polymer based abradable composition.
Claims15
A turbine engine system comprising:
- a turbine engine fan section;
- said fan section including a fan casing and a fan blade rotatable within said fan casing;
- an abradable seal coupled to said fan casing between said fan casing and said fan blade, said abradable seal comprising an abradable composite layer formed by a MAX based solids reinforcement and a polymer based composition, wherein said abradable composite layer includes said MAX phase solids from 1% to 66% by volume and said polymer based abradable composition being the remainder.
A turbine engine abradable outer air seal comprising:
- a casing substrate;
- an abradable composite layer coupled to said substrate;
- and
- said abradable composite layer formed by a MAX based solids reinforcement and a polymer based composition, wherein said abradable composite layer includes said MAX phase solids of between 1 wt. % and 10 wt. % and said polymer based abradable composition being from 90 wt. % to 99 wt. %.
