Abstract: A filter for filtering a fluid that is removed from a vacuum enclosure in an autoclave has a rigid housing comprising of a main body and a lid or cap. The rigid housing defines a filter interior, an inlet, and an outlet. The inlet and outlet arranged such that the fluid has to make at least one turn as the fluid flows in the filter interior. Filter media in the interior catches debris. The filter is constructed to withstand the high temperatures and pressures of imparted by an autoclave. A hose port connects the filter to the vacuum system of the autoclave.

Abstract: An autoclave vacuum system uses two vacuum sources to selectively impart a vacuum. In an exemplary embodiment, the vacuum sources are different types, wherein the first vacuum source is a vacuum pump, and the second source is a Venturi vacuum. The autoclave vacuum system uses a valve system for controlling whether the first and/or second vacuum sources are fluidly coupled to the vacuum enclosure. The valve system allows the autoclave vacuum system to assume a plurality of different configurations chosen such that a constant desired pressure is attained in the autoclave. The valve system may be triggered by a control system configured to recognize and act upon autoclave requirements such as temperature, pressure, duration of use, and number of cycles.

Abstract: A method of in-process inspection includes acquiring a grayscale image of an automated fiber placement (AFP) workpiece, executing a series of detection algorithms on the grayscale image to identify a plurality of characteristics in the grayscale image indicative of one or more defects in the AFP workpiece, and detecting the one or more defects in the AFP workpiece based on the identified plurality of characteristics.
