摘要

Disassembly is becoming a mandatory step in the end-of-life processing for electronic products. More and more regulations call for the removal of hazardous materials and mandate the recovery of components and recyclable materials. It is then no surprise that research has continually looked for more efficient methods of disassembly. Of these methods, active disassembly is at the forefront. Active disassembly incorporates innovative fasteners, which under a special environmental condition will exhibit a disassembling or releasing action. The use of smart materials, more specifically shape memory alloys and shape memory polymers, has been extensively documented. For shape memory polymers, past research has shown innovative designs, such as thread-losing screws and deformable brackets. What has not been shown with shape memory polymers, however, is one of the most basic and common fasteners-the snap-fit. This paper examines the design and processing method for creating a shape memory polymer snap-fit and demonstrates its effectiveness as an actively disassembling fastener.
