A method of forming a composite part (10) having a skin (12) and at least one elongated stiffener (14) extending from the skin (12), the method comprising: providing a mold (20) having a mold surface (22, 26) and a respective elongated compaction cavity for each stiffener (14), each compaction cavity (24) opening into the mold surface (22, 26); for each stiffener (14): placing a bagged insert (30) including an insert (40) received in a tubular bag (42) in the respective compaction cavity (24), supporting the stiffener (14) with the bagged insert (30), the stiffener (14) having a first part extending in the compaction cavity (24) snuggly between a side surface of the bagged insert (30) and an adjacent side surface of the mold (20) bordering the compaction cavity (24), the stiffener (14) having a second part connected to the first part and extending over at least one of the mold surface (22, 26) and a top surface of the bagged insert (30); placing a skin (12) over and in contact with the mold surface (22, 26), and over and in contact with the second part of each stiffener (14); forming a sealed enclosure containing the skin (12) and each stiffener (14), the sealed enclosure being formed in part by each tubular bag (42), each insert being located outside of the sealed enclosure; reducing a pressure within the sealed enclosure; removing each insert from the tubular bag (42); and curing the skin (12) and each stiffener (14). An insert assembly and an assembly for forming a composite part (10) are also discussed.
