Abstract:

This report presents fatigue design data on joints using fatigue- improvement fasteners. The major emphasis is placed upon low-load transfer specimens made of 7075-T73 and T7351 aluminum, assembled with PH13-8Mo and Ti- 6Al-4V fasteners using the TaperLok, HiTigue, and split-sleeve mandrelized hole- fastening systems. The study revealed that the fatigue properties of fastener joints with mandrelized holes were similar to those of fastener joints with the TaperLok and HiTigue fastener systems. A method of condensed data presentation in MIL-HDBK-5 is proposed along with data requirements for future programs.
