Forming duct structure with overbraided woven fiber sleeve

A method for manufacturing, comprising:

• forming a first duct section with a tubular first sidewall extending longitudinally between a first duct section first end and a first duct section second end, a first opening extending through the tubular first sidewall longitudinally between the first duct section first end and the first duct section second end, and the forming of the first duct section including disposing a first woven fiber sleeve over a first mandrel and disposing a polymer material with the first woven fiber sleeve;
• forming a second duct section with a tubular second sidewall extending longitudinally between a second duct section first end and a second duct section second end, the forming of the second duct section including disposing a second woven fiber sleeve over a second mandrel and disposing the polymer material with the second woven fiber sleeve;
• inserting the tubular second sidewall through the first opening and into an interior of the first duct section, the second duct section engaging the tubular first sidewall, and the second duct section first end located at the first opening;
• and
• forming a duct structure by attaching the second duct section to the first duct section.
