Abstract
An aircraft structural joint comprising a first structural component provided with an attachment hole that is configured to receive an corresponding attachment fastener provided by a second structural component; a curable composite bush compressed and cured between an outer diameter of the attachment fastener and the attachment hole when the first component is mounted to the second component, wherein the curable composite bush, when cured, prevents radial displacement of the attachment fastener within the attachment hole.
Claims4
An aircraft joint comprising:
- a first structural component provided with an attachment hole configured to receive a corresponding attachment fastener provided by a second structural component;
- a curable composite bush compressed and cured between an outer diameter of the attachment fastener and the attachment hole when the first structural component is mounted to the second structural component,
- wherein the curable composite bush prevents radial displacement of the attachment fastener within the attachment hole,
- wherein the curable composite bush comprises a hollow cylindrical body formed from a matrix material pre-impregnated with reinforcement fibers, and
- wherein the reinforcement fibers of the curable composite bush are oriented in a circumferential direction about a longitudinal axis of the bush, wherein the hollow cylindrical body defines a plurality of corrugations extending between an inner and an outer diameter of the bush, and wherein the corrugations improve a compressibility of the bush in a direction collinear to a longitudinal axis of the bush.
