Apparatus for forming composite plies on a contoured tool includes a forming head for forming the composite plies on the tool. The forming head is mounted on a manipulator and includes a compliant nosepiece adapted to conform to the contoured tool.

Method and apparatus for fabricating contoured laminate structures

A composite part, such as a stiffener is formed in place. A composite charge is placed on a tool spanning a mold cavity, with the centerline of the charge offset from the centerline of the mold cavity. Opposite sides of the charge are held against the tool as the charge is formed into the mold cavity. One side of the charge is held against movement on the tool while the other side of the charge is allowed to slip over the tool toward the mold cavity.

Apparatus for forming fuselage stringers

A method is provided of fabricating a composite stiffener having a curved web and at least one curved flange. A substantially straight length of unidirectional prepreg tape is placed on a carrier. The at least one curved flange is formed by using the carrier to steer a first portion of the tape onto a first curved tool surface. The curved web is formed by using the carrier to form a second portion of the tape onto a second curved tool surface.

Method for forming fuselage stringers

A device uses magnetic force generated by a magnet to intensify compaction pressure applied to a composite laminate.
