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

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.

Heating apparatus for a composite laminator and method

A system and method for measuring the profile of an external surface of a part is provided. The system includes a source of light that directs light onto a region of the external surface of the part. The system also includes a linear, light-sensitive sensor, and a lens used to image locations within the region onto the sensor. The source of light and the sensor are located substantially within the same plane such that the sensor detects substantially only light scattered, diffracted, or reflected from the region and travelling substantially within the plane. The system additionally includes a re-positionable mirror that re-directs the light emitted from the source of light to the plurality of locations within the region and re-directs light scattered, diffracted, or reflected from the plurality of locations within the region to the lens and the sensor. An automatic gain control system which controls the output power of the source of light to thereby avoid saturating the exposure of the sensor may also be included in the above system. Further, a spring which functions as a low-pass filter may be used to couple the motor to the shaft of the rotating mirror. In another embodiment, a re-positionable polygon mirror system comprising standoffs with tangs which restrict the outside reflecting mirror surfaces to pre-aligned planes during rotation of the polygon mirror system is disclosed. A fail-safe eye safety technique is also disclosed which controls the power to the source of light. Even further, an optical scanning system is disclosed which utilizes bi-cell photo-detectors to determine the angular position of the source of light with high precision.

Profiling of a component having reduced sensitivity to anomalous off-axis reflections

A system for measuring the external surface profile of a component using a non-contact optical technique which scans the field of view with a spot of light through a range of angles by utilizing a rotating mirror system and which precisely determines the angular position of the spot of light during scanning.
