Appl. No.:

10/233270

Inventors:

Kurtis S. Willden - Kent WA
Christopher G. Harris - Auburn WA
Barry P. Van West - Bellevue WA

Assignee:

The Boeing Company - Seattle WA

International Classification:

B29C 4320

US Classification:

264257, 264258, 264292, 264324

Abstract:

A method for forming composite materials is presented, including providing a composite charge wider than a first surface of a mandrel, and positioning the composite charge across the first surface of the mandrel. The portion of the composite charge overhanging the first surface of the mandrel is supported and urged against the mandrel while supporting the unbent portion of the composite charge substantially parallel to the first surface of the mandrel. The invention also provides a system, using a compression mold of forming bladders and heater plates, to form a composite charge over a mandrel, while supporting the unbent portions of the composite charge during forming substantially parallel to the upper surface of the mandrel. The present invention minimizes the shear zone where plies in the composite laminate charge slide past one another during the forming process reducing or eliminating out-of-plane fiber buckling.

US Classification:

425504, 425389, 425414, 425294, 901 41, 901 30

Abstract:

A machine and a method for forming composite materials are provided. The machine includes a frame and at least one forming beam attached to the frame, the at least one beam being arranged to align with a mandrel. The forming beam is pivotally segmented into at least two segments to conform to the shape of the mandrel, or alternately is bendable to conform to the shape of the mandrel. The mandrel is receivable within the frame in alignment with the forming beam. An apparatus is also provided to position a composite charge over the mandrel, and to position the mandrel within the frame. A further apparatus is provided to transport the mandrel, and to urge the mandrel toward the forming beam, forming a composite charge.

International Classification:

E21B 36/04

US Classification:

166 60, 392301, 166302

Abstract:

Certain embodiments provide a heating system configured to heat at least a part of a subsurface formation. The system includes an electrical power supply. A heater section includes one or more electrical conductors electrically coupled to the electrical power supply. The heater section is configured to be placed in an opening in the formation. At least one of the electrical conductors includes ferromagnetic material. The heater section provides a first heat output when time-varying electrical current is applied to the heater section below a selected temperature, and provides a second heat output approximately at and above the selected temperature during use. The second heat output is reduced compared to the first heat output. The system is configured to allow heat to transfer from the heater section to a part of the formation. The system is configured to allow a frequency of the applied time-varying electrical current to be varied.

US Classification:

392301, 166 60

Abstract:

A heater system may include an alternating current supply and an electrical conductor. Alternating current may be applied to one or more electrical conductors at a frequency between about 100 Hz and about 1000 Hz. The electrical conductors may be located in a formation. The electrical conductors may resistively heat upon application of the alternating electrical current. At least one of the electrical conductors may include an electrically resistive ferromagnetic material. The electrical conductor may provide a reduced amount of heat above or near a selected temperature. Heat may transfer from the electrical conductor to a part of formation.
