Publication number: 20130161845Abstract: A method of forming an optical surface on a solar collector that is made from a composite material adds epoxy to the collector. The epoxy is applied to a mandrel that has an outer surface shaped to conform to a concave side of the collector. The concave side of the collector is laid over the mandrel and into contact with the epoxy. The collector is set on the mandrel by first aligning one of the elongate edges of the collector with an elongate edge of the mandrel. Pivoting the collector about the interface defined between the edges of the collector and mandrel produces a wave front in the epoxy, so that when the collector is laid down onto the mandrel, a substantially uniform layer of epoxy is disposed between the collector and mandrel. Heating the resin bonds it to the collector and forms a substantially smooth optical quality surface.Type: ApplicationFiled: December 5, 2012Publication date: June 27, 2013Inventor: Robert Romeo
