An apparatus and associated method for removing backing film from tape during a fiber placement process. A passive (non-powered) take-up roller is used to wind up the backing film that has been separated from the tape.

Backing film removal for fiber placement machine

A method of fabricating a composite item may include dispensing a composite material comprising a reinforcement and a resin. The method may further include energizing an infrared heat source. The infrared heat source may tend to generate a wavelength of electromagnetic radiation that is preferentially absorbed by the reinforcement. The method may additionally include controlling power to the infrared heat source to cause the infrared heat source to emit a wavelength of electromagnetic radiation that is absorbed by the resin to a relatively greater extent than the wavelength of electromagnetic radiation that is absorbed by the reinforcement.

Heating method for a composite laminator

An end effector constructing composite members, in which a compaction roller and redirect rollers translate synchronously along the compaction axis. Additionally, the end effector includes an advantageous arrangement of spools and rollers that directs tow to the redirect rollers at substantially a right angle. Movement of the compaction roller along the compaction axis induces little, if any, changes in tow tension. The substantially constant tow tension advantageously reduces rewinding of the tow supply spools, which can degrade the quality of the lay up and contribute to despooling problems.

End effector  for constructing composite members

The present invention provides an apparatus and associated method for removing backing film from tape or tape during the fiber placement process. The present invention uses a passive (non-powered) take-up roller to wind up the backing film that has been separated from the tape.

Backing film removal system and method for fiber placement machine

To fabricate a composite item, an infrared heat source is energized and a composite material is dispensed. The composite material includes a reinforcement and a resin. In addition, the composite material is applied to a substrate of previously applied composite material. The infrared heat source is configured to emit a wavelength of electromagnetic radiation that is absorbed by the resin to a relatively greater extent than the wavelength of electromagnetic radiation is absorbed by the reinforcement.
