Aspects of the present disclosure include various exemplary methods relating to composite lamination using one or more arrays of parallel material dispensing heads. In one example, a method of fabricating a high aspect ratio composite article is disclosed which may involve applying a first strip material to a work surface datum at a first angle with a first material dispenser, and applying a plurality of second strip materials to a work surface datum each at a second angle with a plurality of rotatable parallel material dispensers. The method may also involve advancing the first material dispenser and the rotatable parallel material dispensers as a unit the width of the second strip material and continuing application of the first strip material by the first material dispenser and a plurality of second strip materials by the rotatable parallel material dispensers until a desired length is reached.

Composite lamination using array of parallel material dispensing heads

Aspects of the present disclosure include various exemplary embodiments of systems and methods relating to composite lamination using one or more arrays of parallel material dispensing heads. In one embodiment, a method of fabricating a high aspect ratio composite article generally includes applying a first strip material to a work surface datum at a first angle with a first material dispenser, and applying a plurality of second strip materials to a work surface datum each at a second angle with a plurality of rotatable parallel material dispensers. The method also includes advancing the first material dispenser and the rotatable parallel material dispensers as a unit the width of the second strip material and continuing application of the first strip material by the first material dispenser and a plurality of second strip materials by the rotatable parallel material dispensers until a desired length is reached.

The feed rate of an ultrasonic knife used to cut composite material is optimized using adaptive control. One or more parameters such as ultrasonic power or side load on the knife is sensed and used to generate feedback control signals. The feedback control signals are used to optimize the commanded feedrate of the knife.
