Abstract:
Aircraft (12) that incorporates a rounded-hat composite stringer (14) connected to an inner side (21) of the skin of the aircraft (12) to form an elongate conduit (40) that defines a conduit axis (46), where the conduit axis (46) includes at least one curving portion. The rounded-hat composite stringer (14) can be manufactured by constructing (102) a lower forming die (72) and an upper forming die (74), each forming die having a length and defining a curve (34) along at least a portion of the length of the die, cutting (104) a pre-cured flat composite charge (70) dimensioned to form the rounded-hat composite stringer (14), pressing (106) the flat composite charge (70) between the lower (72) and upper (74) forming dies (72) to shape the composite charge (70) into a pre-formed stringer (14) having an inner side (21) between curved fillet portions (34), contacting (108) a forming member (90) against the inner side (21) of the pre-formed stringer (14), applying radius fillers (42) to the curved fillet portions (34) of the pre-formed stringer (14), curing (112) the pre-formed stringer (14), and removing the forming member (90) from the cured stringer.
