TEMPLATING METHOD OF STRUCTURE

PURPOSE:To enable the templating, etc., of the internal surface of a vessel, which is diffucult to be rapped and has a small opening, by solidifying a shape memory polymer liquid and storing the three dimensional shape of the surface of a structure. CONSTITUTION:When an in-pipe shape, in which one p...

Zusammenfassung:	PURPOSE:To enable the templating, etc., of the internal surface of a vessel, which is diffucult to be rapped and has a small opening, by solidifying a shape memory polymer liquid and storing the three dimensional shape of the surface of a structure. CONSTITUTION:When an in-pipe shape, in which one part of a pipe 1 is expanded, is templated, a working port 2, which has the filling pipe 4 of a shape memory polymer liquid, an agitator 5 and an electric heater 6 and in the periphery of a lower end of which a packing is fitted, is inserted from the lower section of the pipe 1. The shape memory polymer liquid is injected, and agitated by the agitator 5 and reacted and solidified, thus obtaining a shape memory polymer molding 3 having a glass transition point of 40 deg.C. The molding is heated at 40 deg.C or higher by the electric heater 6, the molding is extracted as a rubbery state, and heated again and the in-pipe shape is restored.
