Abstract: The present disclosure generally relates to methods of using boron-containing additives for crosslinking polysilazane green fibers, which are precursors to silicon carbide fibers. These methods provide a controllable process for crosslinking silicon carbide fibers while providing a simple way for the introduction of boron as a sintering aid into the polymer structure.

Abstract: A slot liner for a stator assembly in one embodiment includes a mesh structural member and a coating. The coating is disposed on at least one side of the mesh structural member, and includes a mixture of a filler and a polyimide resin. The filler is a high thermal conductivity electrical insulating (HTCEI) filler, and includes particles of at least one of boron nitride, aluminum nitride, or a diamond material.

Abstract: A slot liner for a stator and/or a rotor of an electric machine includes a body configured to be received within a stator slot and/or within a rotor slot. The body extends from a first end to an opposite second end and from a first edge to an opposite second edge. The body includes an inner segment and first and second outer segments that extend along the body. The first and second outer segments flank the inner segment such that the inner segment extends between the first and second outer segments along the body. The inner segment includes at least one different material such that a thermal conductivity of the inner segment is greater than a thermal conductivity of the first and second outer segments.

Abstract: A slot liner is provided for a stator and/or a rotor of an electric machine and includes a body configured to be received within a stator slot of the stator and/or within a rotor slot of the rotor. The body extends a length from a first end to an opposite second end and a width from a first edge to an opposite second edge. The body includes an inner segment and first and second outer segments that extend along the length of the body. The first and second outer segments flank the inner segment such that the inner segment extends between the first and second outer segments along the length of the body. The inner segment includes at least one different material than the first and second outer segments such that a thermal conductivity of the inner segment is greater than a thermal conductivity of the first and second outer segments.
