Fastener joints with enhanced strength for composite components

A method of joining a composite body and a load body, the method comprising:

• aligning the load body relative to the composite body;
• forming a first fastener opening in the composite body;
• forming a second fastener opening in the load body;
• installing a first fastener extending along an insertion axis through the first fastener opening and the second fastener opening to connected the composite body and the load body together, the first fastener configured to transmit forces therebetween;
• installing a second fastener extending along an insertion axis through the composite body and the first load body at a location circumferentially spaced from the first fastener;
• wherein the first fastener has a non-circular cross-section orthogonal to the insertion axis;
• wherein the first fastener includes a first lateral side extending between a first lateral end and a second lateral end, and a second lateral side extending between the first lateral end and the second lateral end;
• wherein the second fastener includes a third lateral side extending between a third lateral end and a fourth lateral end, and a fourth lateral side extending between the third lateral end and the fourth lateral end;
• and
• wherein a length between the first lateral end and the second lateral end is greater than a maximum width between the first lateral side and the second lateral side and a length between the third lateral end and the fourth lateral end is greater than a maximum width between the third lateral side and the fourth lateral side.

A joint assembly comprising:

• a composite body having a first fastener opening extending therethrough;
• a first load body having a second fastener opening extending therethrough;
• and
• a first fastener extending along an insertion axis through the first fastener opening and the second fastener opening to connect the composite body and the first load body together, the first fastener configured to transmit forces therebetween;
• a second fastener extending along an insertion axis through the composite body and the first load body at a location circumferentially spaced from the first fastener;
• wherein the first fastener has a non-circular cross-section orthogonal to the insertion axis, the first fastener includes a first lateral side extending between a first lateral end and a second lateral end, and a second lateral side extending between the first lateral end and the second lateral end, and the first fastener includes a first major axis extending between the first lateral end and the second lateral end, and wherein the first major axis is transverse to the body axis;
• wherein the second fastener includes a third lateral side extending between a third lateral end and a fourth lateral end, and a fourth lateral side extending between the third lateral end and the fourth lateral end, the second fastener includes a second major axis extending between the third lateral end and the fourth lateral end, and the second major axis is transverse to the first major axis;
• wherein a length between the first lateral end and the second lateral end is greater than a maximum width between the first lateral side and the second lateral side and a length between the third lateral end and the fourth lateral end is greater than a maximum width between the third lateral side and the fourth lateral side.
