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.

Abstract: An automated fiber placement assembly forms a component by the placement of separate or multiple layers of fiber tows. The automated fiber placement assembly comprises a cutter assembly defining a cut shape. A backplate is spaced from the first cutter assembly against which cutter assembly can cut the fiber tows. The fiber tows define a longitudinal axis and are fed between the first cutter assembly and the backplate in a feed direction. The cutter head assembly is rotatable and movable to vary the orientation of the cutter assembly in order to define different cut shapes non-orthogonal to the longitudinal axis.
