    Abstract: Methods and apparatus to form venting pathways in pressure sensitive adhesives for laminate stacks are disclosed. An example method includes forming a laminate stack including a gas permeable nonwoven layer and a pressure sensitive adhesive layer. The pressure sensitive adhesive layer has a first surface and a second surface located opposite the first surface. The first surface contacts the gas permeable nonwoven layer. The method further includes processing the laminate stack by reducing a ductility of the pressure sensitive adhesive layer such that venting pathways are formed in the pressure sensitive adhesive layer in response to a mechanical strain applied to the pressure sensitive adhesive layer via a trapped gas. The venting pathways extend through a thickness of the pressure sensitive adhesive layer to enable the trapped gas to pass through the pressure sensitive adhesive layer from the second surface to the first surface.

    Abstract: Methods and apparatus to vent gas and vapor from a panel via venting channels for a decorative layer are disclosed. An example apparatus includes a decorative layer, an adhesive layer to couple the decorative layer to a panel, and a resin layer disposed between the decorative layer and the adhesive layer. The adhesive layer is coupled to a first side of the resin layer. The decorative layer is coupled to a second side of the resin layer. The first side of the resin layer defines venting channels to vent at least one of gas or vapor away from the decorative layer to deter the at least one of gas or vapor from exerting a pressure on the decorative layer to deter separation of a portion of the decorative layer from the resin layer. The venting channels have a depth to impede the adhesive layer from filling the venting channels.

    Abstract: 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.

    Abstract: Systems and methods are provided for utilizing pellet-loaded bladders to consolidate and/or harden composite parts. One embodiment is a method for fabricating a composite part. The method includes laying up a preform that is made of fiber reinforced material and that includes a cavity, inserting one or more bladders that are loaded with expandable pellets into the cavity, inflating the bladders in response to a triggering condition, consolidating the preform while the bladders are inflated, deflating the bladders, and removing the bladders from the cavity.
