Abstract
A ceramic matrix composite (CMC) fastener is provided and comprises a CMC material forming a body portion including a plurality of continuous fibers disposed in a matrix. The body portion defines a body length in an axial direction. The body portion defines a first end and a second end opposite the first end along the body length. The body portion includes a head formed at the first end and a shank extending from the head along the body length. The plurality of continuous fibers extend across the head and the shank.
Claims20
A ceramic matrix composite (CMC) fastener, comprising:
- a CMC material forming a body portion including a plurality of continuous fibers disposed in a matrix, wherein the body portion:
- defines a body length in an axial direction;
- defines a first end and a second end opposite the first end along the body length;
- and
- includes a head formed at the first end and a shank extending from the head along the body length,
- wherein the plurality of continuous fibers extend across the head and the shank.
A method of forming a ceramic matrix composite (CMC) fastener, the method comprising:
- rolling a CMC ply of a CMC material to form a body portion, the CMC ply having a plurality of continuous fibers disposed in a matrix, wherein rolling the CMC ply to form the body portion orients the plurality of continuous fibers along a body length of the body portion, the body length extending in an axial direction, wherein the body portion defines a first end and a second end opposite the first end along the body length;
- and
- defining a head at the first end of the body portion.
A fastener system, comprising:
- a ceramic matrix composite (CMC) fastener including a CMC material forming a body portion having a first plurality of continuous fibers disposed in a 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 of the body portion, wherein the head is swaged at the first end of the body portion;
- an interlock feature formed at the second end of the body portion, wherein the interlock feature is swaged at the second end of the body portion;
- and
- a shank extending from the head along the body length to the interlock feature;
- and
- an eccentric cam lock selectively receivable on the interlock feature of the CMC fastener and engageable with the shank of the CMC fastener.
