Original Abstract Submitted
Methods and apparatus for forming a composite structure with a bend in a web and a number of flanges of the composite structure are presented. A flat uncured composite laminate is placed in contact with a forming surface of a mandrel. Pressure is applied to a portion of the flat uncured composite laminate over a kink region in the forming surface of the mandrel to form a bent laminate. The bent laminate and the mandrel are placed into a forming assembly. Overhanging portions of the bent laminate are bent into contact with sides of the mandrel by the forming assembly to form the composite structure, the composite structure having the bend in a web of the composite structure in contact with the forming surface of the mandrel and a number of flanges in contact with the sides of the mandrel.
