Abstract:
1. An assembly comprising: a fiber-reinforced composite structure having a first side and a second side opposite the first side, the fiber-reinforced composite structure including: a bushing having a hemispherical end and a flat end opposite the hemispherical end, the bushing defining a second bore centered within the hemispherical end and extending through the center of the flat end; wherein the hemispherical end of the bushing is configured to nest within the hemispherical well defined by the composite structure such that the flat end of the bushing is flush with the surrounding composite panel; a fastener configured to extend within both of the first bore and the second bore, the fastener including a non-circular head and a body extending from the head, the body configured to extend within the first bore and the second bore, and the head configured to contact the flat surface of the bushing, and wherein the fastener is configured to apply a compressive load against the flat end of the bushing; wherein the flat end of the bushing includes a receiving portion, the receiving portion including a non-circular outer profile that is configured to interlock with the head of the fastener to prevent rotation of the fastener relative to the bushing; and wherein a portion of the body of the fastener distal to the head is radially deformed outwardly to prevent the fastener from being withdrawn from the first bore.
