Abstract

A curable composite bush for an aircraft joint comprising a generally hollow cylindrical body formed from a matrix material impregnated with a reinforcement material substantially composed of fibers, the fibers being oriented in a generally circumferential direction about a longitudinal axis of the bush. The body may define a plurality of corrugations extending between an inner and an outer diameter of the bush to improve the compressibility of the bush in a direction substantially collinear to a longitudinal axis of the bush.
