Abstract: A method of making a fibrous part is provided. The method may comprise forming a porous structure with an annular geometry. A first entrance channel and a second entrance channel may be formed with the entrance channels defined by a surface of the preform. The entrance channels may also extend in a radial direction from an inner diameter of the annular porous structure partially across the surface. An exit channel may be formed between the entrance channels and defined by the surface. The exit channel may extend in a radial direction from an outer diameter of the annular porous structure partially across the surface.

Abstract: The present disclosure provides a multi-leaved core damping disk comprising an annular-shaped first disk half, an annular shaped second disk half, and a multi-leaved core axially aligned with, and disposed therebetween.

Abstract: A disk brake system, in accordance with various embodiments, includes a pressure plate having a center, an inner radius and an outer radius. The disk brake system also includes a first piston. The disk brake system also includes a first puck coupled to the first piston and configured to contact the pressure plate at a first distance from the center in response to the first piston being actuated. The first distance is different than an average of the inner radius and the outer radius.

Abstract: Friction disks, such as rotors and stators, including floating wear liners are disclosed. The friction disks may include a core and a floating wear liner configured to contact a contact surface of the core. The cores may include a retention ring that is substantially concentric with the core and extends axially beyond the plane of the contact surface. The retention ring may radially constrain the floating wear liner in a position aligned with the contact surface to provide frictional contact with the core during braking.

Abstract: Friction disks, such as rotors and stators, including keyed wear liners are disclosed. The friction disks may include a core and a replaceable wear liner coupled to each side of the core. The wear liners may include a plurality of keys which engage key notches in the core. The key notches may prevent the wear liners from rotating with respect to the core in response to a shear force, such as a force applied during braking.

Abstract: Friction disks, such as rotors and stators, including floating cores are disclosed. The friction disks may include a carrier plate and a wear liner coupled to each side of the core. The floating core may be located between the wear liners. The floating core may include a key which is located within a key notch in the carrier plate. The key may prevent the floating core from rotating relative to the carrier plate.

Abstract: An optimized fiber tow orientation, to achieve substantially uniform fiber tow volume across the web, e.g., from inner diameter (ID) to the outer diameter (OD) of a disc shaped preform, without substantially varying the angles of the plurality of fiber tows radially or circumferentially is described herein. Utilizing the systems and processes described herein, a net shape preform may be created. A substantially continuous fiber tow may be used to form the preform. The fiber tow angle of each fiber tow may vary, from more radial, such as at the ID, to more tangential, such as at the OD, as the radius increases, such that there is substantially uniform thickness and substantially uniform areal weight from ID to OD of the preform or layer.

Abstract: Systems and methods disclosed herein may be useful for use in a disk brake assembly. In this regard, a disk brake system may comprise a combination of split friction disk assemblies and solid disk assemblies. These split friction disk assemblies and/or solid disk assemblies may be arranged together in any suitable pattern or position.

Abstract: An annular-shaped disk half of a split friction disk assembly for a disk brake system. The disk half includes a friction surface and a non-friction surface. The friction surface is at an axial end of the disk half. The non-friction surface is at an axial end of the disk half on a side opposite of the friction surface. The non-friction surface includes a contact surface and a non-contact surface. The non-contact surface is recessed from the contact surface.
