Abstract
A method of producing a composite article is disclosed that includes generating composite plies from a low tack composite prepreg material, connecting, by an ultrasonic welding device, two or more of the composite plies by increasing their tackiness to form a composite stack, and forming, by a compression molding device, a composite article from the composite stack.

A method of producing a composite article, the method comprising:
- generating composite plies from a composite prepreg material;
- connecting, by an ultrasonic welding device, two or more of the composite plies by increasing their tackiness to form a composite stack;
- and
- transferring the composite stack to a compression molding device and forming a composite article from the composite stack with the compression molding device.

A method of producing a composite article, the method comprising:
- cutting a composite material to form composite plies, the composite material being prepreg material;
- connecting, by an ultrasonic welding device, two or more of the composite plies by increasing their tackiness to form a composite stack;
- and
- transferring the composite stack to a compression molding device and forming a composite article from the composite stack with the compression molding device.

A method of producing a composite article, the method comprising:
- subjecting a composite material to a cutter to form composite plies, the composite material being prepreg material;
- radiating, by an ultrasonic welding device, two or more of the composite plies with ultrasonic energy to form a composite stack, wherein the ultrasonic welding device connects the composite plies by increasing their tackiness;
- and
- transferring the composite stack to a compression molding device and forming a composite article from the composite stack with the compression molding device.
