Study of the behavior of Shape Memory Polymers in the Active Disassembly ProcessAbstract This paper reports on a research experience for a teacher in researching the behavior ofshape memory polymers. The use of active disassembly using smart materials (ADSM) can bean alternative, with the potential to enable a broad range of electronic devices to be activelydisassembled at the same time, reducing the cost of the manual labor or machine operationneeded to disassemble the products. Shape memory polymers (SMP) are promising materials forthis application. The main aim of the present study was to create SMP snap-fits and analyze theeffect of different design parameters on the disassemble time. Six sets of snap-fits with differentdesign parameters were manufactured form a commercial SMP Veritex. They were tested andthe disassemble time was analyzed. According to the results, design parameters showed to have aslight influence in the disassemble time during the active disassemble process. A learning module based on the legacy cycle concept is developed that challenges thestudents to think through the processes and steps required to assemble and disassemble electronicdevices for environmental and recycling requirements. This learning module will be introducedinto a high school mathematics class during the 2011-2012 school year. Assessment of thestudents’ performance will be carried out and reported.
