ABSTRACT:
This invention relates to a relesable attaching apparatus for attaching a portion of a first object to a portion of a second object. The attaching apparatus has an attaching member with walls defining a cavity therein. A rapidly expanding material is placed within the cavity such that when the material is caused to expand, the attaching member will break at a failure zone located adjacent to the cavity. The rapidly expanding material is a composition that undergoes a phase change from a solid to a liquid, wherein the volume of the liquid is larger than the volume of the solid. In operation, an initiator triggers the phase change which causes a pressure build-up in the cavity, thereby loading the attaching member and causing it to break at the failure zone. Accordingly, the first and second objects are freed from one another.
