Method for producing composite materials

Image Number 2 for United States Patent #4900379.

An improved method for producing composite structures is disclosed. In accordance with the method, a first computer representation of the manner in which a plurality of plies are to be cut from a common fibrous material is provided and the representation used to cut the plies from the common material. A second computer representation of the manner in which the plurality of plies are combined to form the composite structure is used to control an ink-jet marking system to sequentially mark a partial composite with the location of a ply. After the partial composite is marked, the ply is manually placed and its placement inspected. The partial composite is then marked, using the ink-jet marking gantry, with the location of the next ply.
