  • Patent number: 11152328
    Abstract: A uniform pressure gang bonding device and fabrication method are presented using an expandable upper chamber with an elastic surface. Typically, the elastic surface is an elastomer material having a Young's modulus in a range of 40 to 1000 kilo-Pascal (kPA). After depositing a plurality of components overlying a substrate top surface, the substrate is positioned over the lower plate, with the top surface underlying and adjacent (in close proximity) to the elastic surface. The method creates a positive upper chamber medium pressure differential in the expandable upper chamber, causing the elastic surface to deform. For example, the positive upper chamber medium pressure differential may be in the range of 0.05 atmospheres (atm) and 10 atm. Typically, the elastic surface deforms between 0.5 millimeters (mm) and 20 mm, in response to the positive upper chamber medium pressure differential.

The skin-to-core bond line mapping system can include a laminate, an adhesive, a separator film, a core, a breather, a layup tool, bagging material, sealant, and a vacuum port. By employing systems and processes that layer separator film over adhesive and applying a core proximate the adhesive, a bagging material can be disposed over the materials to facilitate vacuum compaction, thereby impressing core impressions on the adhesive to map the areas between the skin and core that have good contact. An iterative process is disclosed, in which additional adhesive can be used to build the bond line until contact is made (or engineering tolerance is reached).

  • Patent number: 10800113
    Abstract: Disclosed embodiments provide automated fiber placement techniques for fabrication of parts made from composite materials. Tape plies are wound around a mandrel while a polymer is dispensed on a tape ply shortly before compaction. A bead monitoring system monitors the size and placement of the bead on the tape ply and feeds back information to various process control systems to maintain an optimal bead size.

  • Patent number: 10780611
    Abstract: A method for fabricating a composite structure is provided. A first number of layers of composite material is laid up to form a first set of stiffeners. A second number of layers of composite material is laid up to form a panel. The first set of stiffeners is associated with a first side of the panel. A pre-cured composite strip is positioned on a second side of the panel, opposite the first side. A third number of layers of composite material is laid up on the second side of the panel to form a second set of stiffeners running perpendicular to the first set of stiffeners. The pre-cured composite lies at an intersection between one of the first set of stiffeners and one of the second set of stiffeners. All the layers of composite material are co-cured to form the composite structure.

  • Patent number: 10773431
    Abstract: A structural polymeric composite includes a stiffening layer. The composite is made in a continuous extrusion process in which the stiffening layer is pulled through a cross-head die as a polymer is extruded over it. The layer includes a film or textile carrier, a filler of carbon fibers, fiberglass, organic fibers or minerals forming a mat. A binder may be dispersed over the mat and a second carrier applied. The mat is subjected to heat and pressure to soften the carriers and binder so they penetrate into the interstices of the filler and binds mechanically with them and the carriers and binder bind chemically with each other to form the stiffening layer. A polymer is then extruded over the stiffening layer, which may be used flat, provided with holes or punches for composite action with the polymer, formed into a profile, or segmented to provide spaced-apart stiffening layers.

  • Patent number: 10777433
    Abstract: A wafer bonding method includes placing a first wafer on a first bonding framework including a plurality of outlet holes around a periphery of the first bonding framework. A second wafer is placed on a second bonding framework that includes a plurality of inlet holes around a periphery of the second bonding framework. The first bonding framework is in overlapping relation to the second bonding framework such that a gap exist between the first wafer and the second wafer. A gas stream is circulated through the gap between the first wafer and the second wafer entering the gap through one or more of the plurality of inlet holes and exiting the gap through one or more of the plurality of outlet holes. The gas stream replaces any existing ambient moisture from the gap between the first wafer and the second wafer.

  • Patent number: 10746752
    Abstract: A specimen processing system is capable of processing specimens carried on slides. The specimen processing system can sequentially deliver slides and opposables to specimen processing stations. The specimen processing stations can use the opposables to apply a series of liquids to the specimens. The applied liquid can be moved along the slide using capillary action while the specimen processing stations control the processing temperatures. The applied liquid can be in a fluid-carrying gap. The opposable can contact the slide to vary a cross section of the fluid-carrying gap.

  • Patent number: 10695990
    Abstract: Systems and methods are provided for enhancing edge breathers for composite manufacturing. One exemplary embodiment is an apparatus that includes an edge breather to facilitate manufacturing of a composite part. The edge breather includes a body, ridges disposed along a length of the body that each define an arc which is perpendicular to a lengthwise axis of the body, and openings disposed along the body that enable air to enter a hollow interior that runs along the length of the body. The arcs defined by the ridges resist compressive loads applied to the edge breather and prevent the hollow interior from collapsing under pressure applied to the edge breather by a vacuum bag during manufacturing of the composite part.
