Abstract: An additively manufactured fastener and a method of manufacturing the same are provided. The fastener includes a shank defining an internal passageway and a head defining a distribution plenum in fluid communication with the internal passageway. The head further defines a cooling face defining a plurality of cooling holes for receiving a flow of cooling air from the internal passageway and the distribution plenum. In addition, an impingement baffle is positioned in the distribution plenum and defines impingement holes for directing the flow of cooling air onto the cooling face.

Abstract: A reinforced electrical insulator has a load sustaining mechanical core with a pair of attachment members located at its longitudinal ends. One of the attachment members extends longitudinally into the mechanical core to provide reinforcement to the mechanical core. The mechanical core member is constructed of a rigid, dielectric material with a first end section, a second end section, and a center section. A plurality of weathersheds extending outwardly from the center section of core member in a substantially radial direction relative to the longitudinal axis. The first and second end sections having maximum widths which are larger than the maximum width of the center section. The attachment members have inner portions embedded within the end sections of the core and outer portions extending outwardly from the end sections of the core.
