Ceramic matrix composite fasteners and fastener systems and methods of forming cmc fasteners and fastener systems

A method of forming a ceramic matrix composite (CMC) fastener, comprising:

• rolling a first CMC ply of a first CMC material to form a body portion, the first CMC ply having a first plurality of continuous fibers disposed in a first matrix;
• wrapping a second CMC ply of a second CMC material about the body portion to form a thread portion, the second CMC ply having a second plurality of continuous fibers disposed in a second matrix, the second plurality of continuous fibers winding in a helix about the body portion;
• and
• processing the body portion and the thread portion to join the body portion to the thread portion,
• wherein rolling the first CMC ply to form the body portion orients the first plurality of continuous fibers along a body length of the body portion, the body length extending in an axial direction.

A ceramic matrix composite (CMC) fastener, comprising:

• a CMC material forming a body portion comprising a first plurality of continuous fibers disposed in a first matrix, the body portion defining a first end and a second end opposite the first end along the body length, the body portion including:
• a head formed at the first end, and
• a shank extending from the head along the body length,
• wherein the head is swaged at the first end of the body portion.
