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.
Claims13
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, wherein the energy director includes a compliant fiber material, and the fiber material is a non-woven material;
- 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 to form, at the joint portion, a joint between the first fiber composite part and the second fiber composite part.
