A method and apparatus are provided for forming a composite structure with an automatic placement head, through the use of a non-rotating tooling tablet having first and second substantially oppositely facing surfaces thereof, joined around the peripheries thereof by a side surface of the tablet, with at least one of the first or second surfaces forming a tool surface of the tablet. Layers of pre-impregnated fiber or tape are applied to the tool surface of the tablet by the automated fiber placement head.

Forming a composite structure by filament placement on a tool surface of a tablet

An apparatus and method are provided for performing a high-speed event, such as a cut/add of a tow, in an automated fiber placement process, by initiating the high-speed event prior to a fiber placement head reaching a location along a tool path of the fiber placement head at which it is desired to have the high-speed event completed.

Performing high-speed events 'on-the-fly' during fabrication of a composite structure by automated fiber placement

An apparatus and method are provided for forming a composite part on a tool surface, during an automated fiber placement process, by depositing the composite material onto the tool surface with two or more fiber placement heads which are capable of simultaneous movement independently from each other and the tool surface, but dynamically synchronized for operation with respect to a common time base. Fiber placement heads, and creels for holding composite materials supplied to the fiber placement heads are replaceable during fabrication of the composite part.
