Abstract
A plurality of layers of nonfully cured composite material are joined by a unique combination of steps including debulking and precuring the layers using vacuum followed by pressure and heating. Then spaced apart holes through the layers are generated with a pointed tool using ultrasonic energy which at least softens and smooths the hole wall. The layers are stitched through the holes prior to final curing.
