A method and system for assisting in the manufacture of composite parts such as those used for various high-strength assemblies such as aircraft wings, vertical stabilizers, racing car shells, boat hulls, and other parts which are required to have a very high strength to weight ratio. The system uses laser technology to measure the resultant surfaces of a first manufactured composite part. A computer system analyzes and compares the as-built dimensions with the required production specifications. Supplemental composite filler plies are designed including shape and dimensions. These plies are nested together into a single composite sheet and manufactured to minimize wasted material. The plies are then cut out and applied to the first part guided by a laser projection system for locating the plies on the part. The part is then re-cured. The final assembly is then re-measured for compliance with production dimensions.

Composite part manufacturing compensation system and method

A novel method designs and analyzes composite parts including optimal manufacturing strategies. The invention analyzes part design including curvatures and other surface topology to formulate an optimal strategy for material layup, number of plies, initial orientation angle, and towpath steering vectors. The method computes an optimum starting point for each fiber path and a stagger offset for each successive fiber path to as to eliminate or minimize gaps and overlaps between adjacent plies. Intermediate surfaces are generated by a polynomial discretization method which generates large computational time savings and enhances blending of adjacent zones to control surface smoothness. The method further calculates a variable steering path for the layer taking into account material parameters and limitations such that plies originating in the same location have a variable orientation angle and follow any reference curve generated by the method to maximize strength and minimize weight of the component.

Optimal fiber path generation method for composite part manufacturing

An electronic wire harness assembly system having a transparent pegboard with a rear mounted digital display such as an LCD or plasma display is controlled by a proprietary software program running on a personal computer. The digital display provides peg location illumination, wire run path location illumination, connector shape illumination and location illumination, as well as cable tie location illumination. The operator is visually assisted with notes and videos displayed under the pegboard at the appropriate locations. The pegboard grid is registered to the digital display with simple mouse pointer clicks.

A collapsible and removable cover for an object, including a collapsible, lightweight, waterproof cover member configured to cover a portion of the object, a lightweight support frame which is configured to be manipulated by a user between an expanded operative shape and a collapsed storage shape, and which connects to the cover member in the expanded operative shape such that the support frame and the cover member jointly form a self-supporting cover unit having a stable configuration, and retainers which are configured to secure parts of the support frame to the object. The retainers include first portions which are configured to be secured to the object and second portions which securely connect to the parts of the support frame, and the retainers function as a sole source of connection between the cover unit and the object.
