$139,991Benefit:
Composite materials provide lightweight and tailorable structural solutions which enable lower operating costs for a range of commercial transport applications including aircraft, helicopters, tanks, trucks, and cars. Composites also find application for civil structures including buildings, wind turbines, shipping containers, as well as for medical and sports equipment. Essential to utilizing such composite materials is being able to join composite parts together or to other metallic structural components in a robust manner as designed or as part of a repair operation. Successful multiphase program execution will lead to an optimized friction drilling process for one or more Navy composite systems of interest, as well as a testing/modeling methodology to extend to it to other composite and composite/metallic material systems. This fastener process will find application for primary and secondary structures, as well as structural repair. The developed friction drill tool and process will significantly increase hole drill speeds, while retaining high geometrical tolerance and low secondary damage in composites and composite-metal stacks. Improved hole drilling and fastening methods can lead to lighter structures and longer fatigue life in composites. The development of direct friction drill fastener installation can help speed repair and assembly operations. As such, this technology will help to enable increased composite structure utilization throughout industry for primary and secondary structures, as well as for general structural repair.
