A panel may be formed with mandrels inside of stiffening members. The panel may be coupled to a panel holding jig. A winch may be coupled to the mandrels. The winch may pull the mandrels out of the stiffening members and into curved tracks.

An aerospace vessel including a fuselage, a means for causing the fuselage to fly coupled to the fuselage, and an environmental control system within the fuselage. The environmental control system includes a duct made of closed cell thermoplastic foam, such as polyvinylidene fluoride foam.

A joint for use with a composite laminated component is disclosed herein. The joint includes a component including a partial U-shaped trapezoidal cavity and a triangular component. The partial trapezoidal component includes a base extending in a first direction, a first side extending away from the base at a first angle from the first direction, a second side extending away from the base at a second angle from the first direction and toward the first side, and an opening defined by the first side and the second side. The triangular component is coupled to the base and extending orthogonally away from the base in a second direction and toward the opening.

A method of making a composite filler member with a tailored stiffness from a composite blank. The method includes cutting the elongated fibers within the composite blank and forming a plurality of shorter discrete fiber sections and forming the composite blank into a corrugated configuration. A composite filler material includes cut fiber sections and uncut fibers. A method of making a composite blank includes positioning the composite blank on a support surface and cutting one or more of the elongated fibers within the composite blank and reducing the initial stiffness of the composite blank to a working stiffness.

A fabric assembly and method of manufacturing a spliced liquid-mounted seal sheet is provided. The method includes overlapping a first fabric layer and a second fabric layer, wherein at least one of the first fabric layer or the second fabric layer defines an opening having a shaft defining a channel positioned therethrough, the shaft housing a valve having an open position and a closed position, wherein the valve is configured to allow a fluid through the channel in a first direction while the valve is in the open position, and the valve prevents the fluid through the channel while the valve is in the close position. The method further includes splicing the first fabric layer to the second fabric layer to form a spliced fabric composite comprising an interior pocket space defined by the first fabric layer and the second fabric layer.
