摘要： A method is provided for manufacturing. During this method, a woven fiber sleeve (128) is disposed over a mandrel (130) to provide an overbraided mandrel (132). The woven fiber sleeve (128) includes a base section (138) and a mount section (144). The base section (138) is wrapped circumferentially around the mandrel (130) and extends longitudinally along the mandrel (130) between a first end (140) and a second end (142). The mount section (144) is disposed longitudinally at an intermediate location between the first end (140) and the second end (142). The mount section (144) projects out from the base section (138). The overbraided mandrel (132) is arranged with tooling (148). A polymer material is disposed with the woven fiber sleeve (128) to provide a duct structure (60). The duct structure (60) includes a tubular duct and an annular flange (96). The tubular duct is formed by the base section (138). The annular flange (96) is formed by the mount section (144).

摘要： A method is provided for manufacturing. During this method, a first woven fiber sleeve (136) is disposed over a first mandrel (138) to provide a first overbraided mandrel (140). The first woven fiber sleeve is wrapped circumferentially around the first mandrel. An opening (142) is formed through a side of the first woven fiber sleeve. A second woven fiber sleeve (146) is disposed over a second mandrel (148) to provide a second overbraided mandrel (150). The second woven fiber sleeve is wrapped circumferentially around the second mandrel. The second overbraided mandrel is arranged with the first overbraided mandrel. The second woven fiber sleeve engages the side of the first woven fiber sleeve. A second overbraid first end (151) is disposed at and extends circumferentially around the opening (142). A polymer material is disposed with the first woven fiber sleeve and the second woven fiber sleeve to provide a duct structure.
