摘要

Structural stiffening (14), a stiffened structure (10) and apparatus (37) and method for forming the structural stiffening (14). The structural stiffening (14) is formed using first and second forming means adapted to respectively receive first and second sheets of material (39) and form an upstanding portion (30) in each of said sheets, feed means adapted to feed a filler material (24) between said upstanding portions (30), and fixing means 50 adapted to fix said upstanding portions (30) to said filler material (24). The structural stiffening may be attached to a structure to be stiffened (12) to form a stiffened structure (10).
