Abstract: Process for forming a permanent join between two sections of fibrous material contained in a thermosetting resin matrix, said process comprising overlaying the two sections and subjecting the overlaid sections to ultrasonic welding to form a permanent join between the two sections, wherein there is no significant change in the sub-ambient Tg of the fibrous material contained in the thermosetting resin matrix in the region of the permanent join.
