Abstract:
A composite item is fabricated with a device. The device includes and end effector and a positioning device. The end effector places a tow. The end effector includes a spindle, compaction device, and a path. The spindle detachably secures a spool of tow and the path is disposed from the spool to the compaction device. The positioning device positions the end effector. The end effector is detachably secured to the positioning device.
Abstract:
The present invention provides an apparatus and associated method for removing backing film(216) from tape (204) or tape during the fiber placement process. The present invention uses a passive (non-powered) take-up roller (220) to wind up the backing film that has been separated from the tape.
Abstract:
To fabricate a composite item (16), an infrared heat source (22) 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.
