ARTICLE COMPRISING FIRST AND SECOND PORTIONS FASTENED TOGETHER BY A RELEASABLE FASTENER DEVICE.

摘要

Techniques are described for assisting disassembly of an article by triggering shape transition of shape memory material within the article. In one form, a de-fastener (16) is triggered to expand to break apart first and second parts (10a, 10b) which may be integrally formed, or fastened together. In another form, shape memory polymer is used as a releasable fastener. the shape memory polymer losing shape integrity above a predetermined
