Patent ID: 10690485

Abstract:
A system for determining one or more characteristics of a carbon fiber tow. The system including a first laser profilometer, a second laser profilometer, and a controller. The first laser profilometer is located on a first side of the carbon fiber tow. The second laser profilometer is located on a second side of the carbon fiber tow. The controller is configured to receive, from the first profilometer, a first profile of the first side of the carbon fiber tow, and receive, from the second profilometer, a second profile of the second side of the carbon fiber tow. The controller is further configured to determine at least one characteristic selected from a group consisting of a tow width of the carbon fiber tow, a tow fuzz of the carbon fiber tow, a tow thickness of the carbon fiber tow, and a tow angle of the carbon fiber tow, the at least one characteristic based on the first profile and the second profile. The controller further configured to output the at least one characteristic of the carbon fiber tow.
