Abstract
To improve a method for ultrasonic welding of parts for vehicles and/or aircraft, a method in which an energy director made of non-woven fiber material is arranged between a first fiber composite part and a second fiber composite part to be joined together. A sonotrode is used to join/weld the parts together by pressing on the parts. The energy director is compliant such that a uniform even contact is generated between the first and second fiber composite parts during the welding process.
Claims15
A method for joining a first fiber composite part to a second fiber composite part, the method comprising:
- a) arranging the first fiber composite part and the second fiber composite part to form a joint portion to be joined;
- b) arranging within the joint portion and between the first fiber composite part and the second fiber composite part an energy director that is suitable for influencing propagation of acoustic energy;
- and
- c) arranging a sonotrode on the first fiber composite part and energizing the sonotrode such that acoustic energy is transferred to the joint portion and finally a joint between the first fiber composite part and the second fiber composite part is formed.
