ABSTRACT:
A dimensionally stable structural joint particularly suited for use in space systems. The joint comprises a connector having at least two tubular sleeves, at least two tubular members, and at least two annular clamping means for securing the tubular members inside the connector. The connector comprises at least two elements, manufactured from a fiber reinforced composite, which, when mated, form the connector. The tubular members are manufactured from a material having a coefficient of axial expansion of substantially zero. The annular clamping means are manufactured from a material having substantially the same coefficient of radial expansion as the tubular members. The combination of the connector comprises at least two elements and the annular clamping means with substantially the same coefficient of radial expansion as the tubular members allows the joint to accommodate radial expansion and contraction while maintaining axial dimensional stability.
