ABSTRACT:
A method of fabricating a reflective stretched membrane mirror for use in the collection and focusing of solar energy includes a tensioning fixture to which a plurality of air-actuated cylinders are attached. The piston arm of each cylinder is in turn connected to an air-actuated clamp which is designed to hold a portion of the peripheral edge of the reflective film which is to be stretched. Depending upon the properties of the film and its tensioning characteristics, cylinders which need the same air pressure are connected in common to a single regulator. The regulators are then connected to an air compressor and the sheet of reflective film is tensioned to a desired level at which point it is adhesively bonded to a circular frame. Once a first reflective film is bonded to a top side of the frame, the process is repeated with a second reflective film bonded to tile back or opposite side of the frame. Once both reflective films have been securely bonded to the frame surfaces, a vacuum is pulled on the interior space so as to create a parabolic contour in the film.
