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.
