Abstract
A turbine engine comprising a compressor section, combustor section, and turbine section in serial flow arrangement, and defining an engine longitudinal axis. The turbine engine includes an airfoil with an outer wall having a pressure side and a suction side, extending between a root and a tip in a span-wise direction, and extending between a leading edge and a trailing edge in a chord-wise direction. The airfoil includes a woven core, a first bonding layer including a toughened region, and a laminate skin provided exterior of the first bonding layer and bonded to the woven core by the first bonding layer.
Claims20
A turbine engine comprising:
- a compressor section, combustor section, and turbine section in serial flow arrangement, and defining an engine centerline;
- and
- an airfoil, including an outer wall having a pressure side and a suction side, the outer wall extending between a root and a tip in a span-wise direction, and the outer wall extending between a leading edge and a trailing edge in a chord-wise direction, the airfoil rotatable about the engine centerline, the airfoil comprising:
- a woven core;
- a first bonding layer located exteriorly of the woven core, the first bonding layer having a mechanical property defining a first toughness, and the first bonding layer having a first toughened region, with the first toughened region having a first mechanical property defining a second toughness that is tougher than the first toughness;
- and
- a second bonding layer located exteriorly of the first bonding layer, the second bonding layer having a mechanical property defining a third toughness, and the second bonding layer having a second toughened region, with the second toughened region having a second mechanical property defining a fourth toughness that is tougher than the third toughness;
- and
- a laminate skin located exteriorly of the second bonding layer, and bonded to the woven core by the first bonding layer and the second bonding layer.
A fan blade for a turbine engine comprising:
- a three-dimensional woven core;
- a first bonding layer located exteriorly of the three-dimensional woven core and having a first toughened region;
- a second bonding layer located exteriorly of the first bonding layer and having a second toughened region;
- and
- a laminate skin located exteriorly of the second bonding layer.
