Abstract: A method is provided that includes monitoring a process of manufacturing a composite structure that includes introducing a matrix material to a reinforcement material, applying the reinforcement material into a mold cavity or onto a mold surface with a first machine tool, subjecting the matrix material to a melding event with a second machine tool, and inspecting the composite structure. Data including at least one of first measurement data, error data or second measurement data is determined, and an analysis of the data is performed to summarize the data and thereby produce feedback data including a summary of the data. At least one of the process, the first machine tool or the second machine tool is adjusted based on feedback including the summary, and for manufacture of a next composite structure.

Abstract: A method for computer analysis of a quality of an as-programmed surface of a composite laminate. A first data set representing an as-programmed top surface is generated based on as-programmed ply definitions and a tool surface definition. Thereafter, a second data set representing coordinates of points of a first mesh on the as-programmed top surface is generated, which points form a first mesh. Then a third data set representing coordinates of points of a second mesh on a defined tool surface is generated. A respective angle of each mesh element of the first mesh relative to a corresponding mesh element of the second mesh is then calculated. Each angle is compared to a threshold of acceptable angle. In response to an acceptable number of angles exceeding a threshold of acceptable angle, a tow placement machine may be programmed to fabricate a composite structure using the as-programmed ply definitions.
