    摘要: A system for determining cumulative tow gap width includes an in-process vision system having at least one camera adapted to record images of a composite material and a data analysis computer communicating with and adapted to receive image data from the in-process vision system. The data analysis computer may be adapted to calculate a cumulative gap width of tow gaps in the composite material. A user interface may communicate with and be adapted to receive data analysis results from the data analysis computer. A method for determining cumulative tow width gap of tow gaps in a composite structure is also disclosed.

    摘要: A flaw and foreign object debris (FOD) detection system (11) for use during fabrication of a structure (12) includes an illumination device (13). The illumination device (13) is configured to be in proximity with a fabrication system (10) and illuminates a portion (18) of the structure (12). The illumination device (13) directs light rays (16) at acute angles relative to the portion (18). A detector (14) monitors the portion (18) and detects FOD in the portion (18) during fabrication of the structure (12) in response to the reflection of the light rays (16) off of the portion (18).
