A method is provided for the non-contact measurement of variations in thickness of composite materials and structures prepared from composite parts. Metrologic methods are employed to provide a 3D image of the structure or part. Variations that are greater than an acceptable amount can be corrected by adding a compensation layer to the surface of the structure or part.

Composite laminate thickness compensation

A contoured surface planing apparatus for removing proud-standing material from a contoured surface without damaging the surface. The apparatus may include a tool comprising a motor-driven rotary cutter supported by a main body for rotation about a cutter axis, and orientation contact points spaced around the cutter and defining an orientation contact plane disposed parallel to the cutter axis.

Aircraft skin surface planing

A temporary fastener and a method of attaching an aircraft skin to a frame using the temporary fastener during a step of the skin to frame assembly process. The fastener secures the skin to the structure while holes for permanent fasteners are drilled through the skin and frame; the fastener is flush mounted so that an automatic drill can drill the holes without interference. The temporary fastener can be removed after the permanent fastener holes are drilled, and before or after permanent fasteners are inserted within their respective holes.

Method of manufacturing aircraft using temporary fasteners

A method for placing a resin layer or shim on a frame member uses an overpress. The overpress has an inner surface with protruding nubs. The operator places a bead of liquid resin on the inner surface of the overpress, then clamps the overpress to the frame member. The clamps force the nubs of the overpress into contact with the frame member and allows the nubs to define a clearance between the overpress and the frame member. The liquid resin spreads throughout the clearance and cures. After the resin has cured, the overpress is removed from the frame member, leaving a layer of cured resin bound to the frame member. This layer is then machined to a desired thickness.
