摘要： A sealant tape including a base portion, first sealing portion and second sealing portion is provided. The first sealing portion includes a first ridge and the second sealing portion includes a second ridge. The sealant tape is applies to a perimeter portion of a tool such that the base portion of the sealant tape couples to the perimeter of the tool, and a vacuum bag is placed over the tool, contacting the sealant tape, and ultimately is sealed onto the tool via the sealant tape.

摘要： Methods of recovering and/or recycling expanded polymer tooling, the methods including collecting expanded polymer tooling, reducing the collected expanded polymer tooling into smaller particles, treating the reduced expanded polymer tooling in order to yield an at least partially purified recovered polymer composition, and then collecting the at least partially purified recovered polymer composition. The at least partially purified recovered polymer composition can then be used to form new expandable polymer tooling.

摘要： Methods of manufacturing composite workpieces that include positioning a heat-generating element proximate to an uncured composite workpiece, triggering the heat-generating element to produce an exothermic chemical reaction or exothermic physical reaction so that the temperature of the uncured composite workpiece is raised to a predetermined first temperature, and curing the composite workpiece while it is at a temperature that is at least the predetermined first temperature.

摘要： Methods of manufacturing composite workpieces that include adding an expandable element to an internal volume of a constraining container proximate to a uncured composite workpiece supported on a rigid form, where the expandable element is configured to expand when a predetermined change is produced in an attribute of the expandable element; expanding the expandable element by producing the predetermined change in the attribute of the expandable element, so that an expansion of the expandable element applies pressure to the workpiece supported on the rigid form within the internal volume, and curing the composite workpiece while the resulting pressure is applied to the workpiece supported on the rigid form.

摘要： A method and apparatus for a reinforced bladder are provided. The reinforced bladder comprises a bladder with a cross-sectional shape formed of a polymeric material and a number of reinforcements. Each of the number of reinforcements covers only a portion of the cross-sectional shape such that part of the cross-sectional shape remains uncovered by the number of reinforcements.
