Zusammenfassung:	COMPOSITE HAT STIFFENER, COMPOSITE HAT-STIFFENED PRESSURE WEBS, AND METHODS OF MAKING THE SAME There is provided a composite hat stiffener (32), a composite hat-stiffened pressure web, and a method of making the same. The composite hat stiffener has a composite hat section (38) having a first side (40) and a second side (42). The composite hat stiffener (32) further has a plurality of composite stiffening plies (72) coupled to the composite hat section (38). The plurality of composite stiffening plies (72) include a body ply (74) coupled to the first side (40) of the composite hat section (38), a wrap ply (80) coupled the body ply (74), and a base ply (94) coupled to the body ply (74) and the wrap ply (80). The composite hat stiffener (32) further has a pair of radius filler noodles (108) coupled to the composite hat section (38) and disposed between the plurality of composite stiffening plies (72). The composite hat stiffener (32) further has an outer ply (112) coupled to the second side (42) of the composite hat section (38). 40 42 38 46 32a 50 56 56 50 82 110 { \ 4 72 7 4 1 0 0 -- {--- --- 76 78 122 108 102 (2 0 108 100 98 46 __ _46 32a 48 -48 80 -.k 36 50 56 126 106 56 50 \ 74108 108 94
