Abstract:

ABSTRACT: Cornerstone Research Group Inc. (CRG) proposes to design and demonstrate rapid-release fasteners, based on Veriflex shape memory polymers, for application in aerospace structural components. In this Phase I effort, CRG advanced rapid-release fasteners by developing and fabricating designs for increased strength and durability in structural applications and for compatibility with aircraft system integration requirements. CRG worked to define and expand the SMP fastener design toolbox through mechanical performance evaluations conducted throughout the prescribed operational temperature range. The results identified consistent thermally activated and deactivated performance throughout the various tensile, shear, and cleavage peel evaluations. CRG"s SMP fastener system boasts a tensile strength that is 50 times stronger than its activated detachment force.. Design modifications and fabrication strategies developed during this program have demonstrated even greater performance potential for future iterations. CRG"s ability to tailor fastener performance to match application specific requirements using the design toolbox will streamline the process for applying SMP fastener solutions. The project culminated with the fabrication and evaluation of multiple Phase I prototypes that highlighted structural integration techniques, thermal activation methods, and included an access panel concept in preparation for the Phase II representative airframe prototype demonstration. BENEFIT: Operational Benefits: (1) Low force and rapid-release/replace fasteners, (2) cost/weight savings benefits of unitized structure design, and (3) reduces maintenance turn-around time and integration weight. Commercial Applications: (1) Commercial and civil aviation aircraft structural fasteners, (2) underwater or outdoor fasteners to replace metal, and (3) industrial fasteners for adaptable workspace.
