Abstract: A method and apparatus for forming a radius filler. A lattice is formed of connecting elongate members having a three-dimensional shape of the radius filler. A resin is placed within the lattice.

Abstract: A structure comprising a plurality of walls defining a bladder cavity, the bladder cavity comprises an initial cross section size. A first plurality of wave features provided along at least one of the plurality of walls defining the bladder cavity. In one arrangement, the first plurality of wave features allow the structure to expand from the initial cross section size to a second cross section size after the structure becomes inflated during a composite charge cure, the second cross section size larger than the initial cross sectional size.

Abstract: 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.

Abstract: A composite tool for vacuum bag processing composite parts comprises a plurality of laminated composite plies, including a facesheet adapted to have a composite part placed thereon. A gas impermeable barrier layer sandwiched between the composite plies prevents air leaks through the tool.

Abstract: A system and method for forming a composite filler. The method comprises applying a pressure to a first portion of a composite material blank with a pair of forming dies of a composite filler forming apparatus, the pair of forming dies having a pair of convex radii, each forming die of the pair of forming dies having a respective convex radius of the pair of convex radii. The method also repeats the applying step to a subsequent portion of the composite material blank to incrementally form the composite material blank into a desired cross-section along its length.

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.

Abstract: A leak through the thickness of a structure is detected from one side of the structure using a leak detection layer. The leak detection layer exhibits visually observable changes when exposed to an air leak.

Abstract: A composite tool for vacuum bag processing composite parts comprises a plurality of laminated composite plies, including a facesheet adapted to have a composite part placed thereon. A gas impermeable barrier layer sandwiched between the composite plies prevents air leaks through the tool.
