摘要： A stitching system includes a gantry that is movable along a material support table. Mounted to the gantry are a plurality of stitching heads and bobbins. The stitching heads are individually controllable in a z-direction, and the bobbins are individually controllable in the z-direction. Each stitching head is paired with a bobbin. Each pair of stitching heads and the bobbins is controlled synchronously in the z-direction. The stitching system is well-suited for stitching preforms of aircraft wing covers and other preforms having variable thickness and compound, contoured three-dimensional surfaces.

摘要： Native code for a CNC stitching machine is generated by generating a geometry model of a preform; generating tool paths from the geometry model, the tool paths including stitching instructions for making stitches; and generating additional instructions indicating thickness values. The thickness values are obtained from a lookup table. When the stitching machine runs the native code, it accesses a lookup table to determine a thread tension value corresponding to the thickness value. The stitching machine accesses another lookup table to determine a thread path geometry value corresponding to the thickness value.

摘要： A method and apparatus for manufacturing. A fiber layer and a porous bonding layer are formed to form a unidirectional lay-up of fibers. The lay-up of fibers is heated under pressure to form a unidirectional composite tape of desired thickness to substantially maintain the fibers in a desired configuration. The unidirectional composite tape is slit to a desired width, and the slit unidirectional composite tape is loaded into a multiaxial fabric machine. A first layer is built from the composite tape in the multiaxial machine, and a second layer is built from the composite tape on the first layer at a predetermined angle from the first layer in the multiaxial machine. The first and second layers are consolidated to form a composite fabric in a continuous process.

摘要： A resin infusion mold tool system for use in a vacuum assisted resin transfer molding process with a subsequent pressure bleed step. The mold tool system includes a mold assembly having an outer mold line tool connected to resin supply lines and supplying resin to the preform. A plurality of inner mold line tools form a hard interface with the inner mold line of the fiber preform and are held to within tight tolerances by an external locating fixture. Excess resin is drawn out of the fiber preform using a vacuum bag connected to vacuum lines and disposed over the inner mold line tools but not between the tools and the fiber preform. The mold assembly is placed in an autoclave, the resin supply lines are detached and the autoclave pressurized to bleed additional resin out of the preform to raise the fiber volume of the composite structure.
