Abstract: A method of manufacturing cross-corrugated support structures is provided. A mold having a molding surface with a first plurality and a second plurality of corrugations therein is used to introduce corrugations into a flexible, carbonaceous sheet. Cross-corrugations are introduced into the sheet by placing the sheet onto the molding surface, encapsulating the sheet to form a vacuum chamber, and evacuating the vacuum chamber of air. As air is evacuated from the vacuum chamber, the sheet is drawn upon the molding surface causing the sheet to conform to the shape of the molding surface. Thermosetting resin is infused into the sheet and cured causing the sheet to rigidly retain the shape of the molding surface. The sheet is further reinforced by securing at least one support member to the sheet using thermosetting resin.

Abstract: A mold unit (30) defines an elongate cavity (70) and has an injection inlet port (90) for a viscous material at one end of the cavity and an injection outlet port (92) at the other end of the cavity. The mold unit includes a gas vent formed by a gap (G2) between two parts of the mold unit. The gap extends continuously or intermittently in the length direction of the the mold unit, while penetrating through the mold unit in the thickness direction such that it provides fluid communication between an interior space and an exterior space of the cavity. The gap is shaped such that, although gasses pass through, the viscous material does not pass due to fluidity resistance of the viscous material resulting from its viscosity. As a result, the gas vent acts to block leakage of the viscous material while permitting degassing of the viscous material.

Abstract: A method for making continuous encapsulated linear lighting is disclosed. In this method, a PCB is placed within a channel, and the channel is dammed by one or more stoppers. The dammed segment is filled and then caused or allowed to cure. The stoppers are then removed from their initial positions and moved along the channel. If one runs out of channel before the desired length of linear lighting is achieved, a second piece of channel is abutted to the previous segment of channel, the PCB is laid into it, and a segment is dammed, filled, and cured. The process continues iteratively until the desired length is achieved or more channel is required. The PCB may initially be cut to the full desired length and applied to the channel piecewise as needed.
