Abstract
This apparatus uses a programmable controller to control laser beam and standard fiber chopper units. The units usually are affixed to resin mix heads. The conventional choppers use steel blades that are randomly spaced, angled and sized. The PC also varies the speed of the standard chopper. The laser device operates in a manner that allows one to set the pulse rate for the specific purpose of varying the fiber length. During operation, the intensity of the laser may be adjusted to accommodate cutting or different sizes and kinds of fibers. The apparatus preferably produces fiber reinforced urethane substrates such as interior door panels for automobile doors.
