  • Composite material structure and method of manufacturing same
    Patent number: 9352538
    Abstract: A method of manufacturing a composite material structure, such as a strut, includes providing a rigid, elongate, substantially tubular member and coupling a first end fitting to a first axial end of the substantially tubular member. The first end fitting has an undulated outer surface with one or more alternating, annular crests and grooves that extend longitudinally along the first end fitting. The method includes rolling a sheet of pre-impregnated composite fiber around the substantially tubular member one or more times such that the sheet covers the substantially tubular element and extends at least partially over the undulations of the first end fitting. The method includes curing the pre-impregnated composite fibers in the rolled sheet.
