  • Patent number: 9962917
    Abstract: A vacuum bag (18) is placed around the inner forming surface (IML) of an inner mandrel with radially retractable sectors (11a, 11b) having parallel longitudinal slots (17) with composite stringers (30) in the slots (17). An inner support (31) in each stringer is covered by an impermeable tubular bag (32). A composite skin (37) is laminated around the stringers (30), the coated supports (31, 32) and the inner forming surface (IML). An outer curing tool (50, 51) closes around the skin (37) defining an fuselage barrel outer forming surface (OML), leaving an annular gap (G) between the skin outer surface (37) and the outer forming surface (OML). Vacuum is applied between the vacuum bag (18) and the outer tool (50, 51), enlarges the uncured barrel diameter, releasing the barrel from the inner mandrel (10) and bringing the skin outer surface (37) into contact with the outer tool inner surface (IML).

  • Patent number: 9862174
    Abstract: A method of producing a stretch laminate exhibiting reduced defects from a mechanical activation process can include providing a nipping member. The nipping member can have a first nip region and a non-nip region adjacent to the first nip region. A first substrate and an elastic element are provided to the nipping member. The first substrate and the elastic element are joined in a face to face relationship with adhesive therebetween, thereby creating an intermediate laminate. The intermediate laminate has a first tack down region and an activation region adjacent the first tack down region. A portion of the first tack down region passes through the first nip region, and a portion of the activation region passes through the non-nip region of the nipping member. The activation region of the intermediate laminate is mechanically activated, thereby creating the stretch laminate.

  • Patent number: 9862154
    Abstract: Apparatuses and methods of the present disclosure relate to efficient sealing of vacuum bag seams for vacuum bag processing of composite parts. Vacuum bags may enclose a composite part and form a first sealed region around the composite part. The first sealed region may be sealed by vacuum bag seams to a base supporting the composite part and/or to other vacuum bags. The vacuum bag seams may be sealed with an edge sealing frame that forms a compression seal and that defines a second sealed region including the sealed seam. Vacuum applied to the second sealed region forms a vacuum moat adjacent to the seam and/or at least partially surrounding the first sealed region. Hence, minor leaks in the compressively sealed seam are mitigated by the vacuum moat and the vacuum integrity of the first sealed region is maintained despite some potential leaks in the sealed seam.

  • Patent number: 9669186
    Abstract: A method of manufacturing a splittable/peelable tubular body of a catheter or sheath wherein the tubular body has a splittable/peelable atraumatic tip is disclosed. The atraumatic tip is generally softer than the tubular body. The tubular body and atraumatic tip each comprise a peel mechanism longitudinally extending along their respective lengths. The peel mechanisms are formed by longitudinally extending regions of interfacial bonding between first and second longitudinally extending strips of polymer material. Each strip forms at least a portion of an outer circumferential surface of the tubular body and atraumatic tip. A region of stress concentration extends along the region of interfacial bonding. The stress concentration facilitates the splitting of the tubular body and atraumatic tip along their respective peel mechanisms.

  • Patent number: 9656450
    Abstract: An apparatus for laminating substrates includes a laminating fixture having an open-topped recessed space formed by a pair of corresponding sidewalls for holding a target substrate therein. The recessed space is communicable with an air evacuation passage. A supporting structure is formed in the recessed space for supporting two opposite ends of a flexible substrate thereon, such that a bottom of the flexible substrate is spaced from a laminating surface of the target substrate by a predetermined distance. A soft plate is disposed over the open-topped laminating fixture to form an airtight chamber in the laminating fixture. When the airtight chamber is vacuumed using a vacuum pump via the evacuation passage, the soft plate is subjected to a suction pressure and downward deformed to press the flexible substrate downward, causing the flexible substrate to deflect to attach its bottom on the laminating surface of the target substrate.
