B23P 17/00

US Classification:

428 347, 428 341, 428 358, 295271

Abstract:

A columnar structure comprises a generally hollow laminate core, an outer composite skin, and a sleeve-like reinforcement. The sleeve-like reinforcement surrounds the laminate core and is sandwiched between the laminate core and the outer composite skin for reacting compressive loads imposed on the columnar structure.

International Classification:

B29C 33/50
B29C 70/34

Abstract:

A structure comprising a plurality of walls defining a bladder cavity, the bladder cavity comprises an initial cross section size. A first plurality of wave features provided along at least one of the plurality of walls defining the bladder cavity. In one arrangement, the first plurality of wave features allow the structure to expand from the initial cross section size to a second cross section size after the structure becomes inflated during a composite charge cure, the second cross section size larger than the initial cross sectional size.

International Classification:

B64C 1/06
B64F 5/10
B29D 99/00
B29C 33/30

Abstract:

Methods of assembling stiffened composite structures are disclosed. Some methods include forming a stiffener assembly by compacting it within a trough formed in a trunnion. A single trunnion may accommodate two or more different types of stiffeners, thereby avoiding the need for multiple sets of tooling. In some methods, a plurality of stiffener segments may be spliced together, thereby avoiding the need to transport and handle an entire stiffener. A vacuum chuck may be utilized in some examples to transfer the stiffener assembly from the trunnion to a transfer tool. The same vacuum chuck may be transferred along with the stiffener assembly on the transfer tool and loaded onto an inner mold line layup mandrel, where the vacuum chuck may be used to compact the stiffener assembly to the inner mold line layup mandrel.
