Delamination and edge damage repair on thermoplastic composites
A method of repairing a thermoplastic composite material is disclosed herein. The method includes placing the thermoplastic composite material on a supporting anvil, placing an energy transmission material on top of the thermoplastic composite material, and applying an ultrasonic welder to the thermoplastic composite material to consolidate and repair the thermoplastic composite material. Another method of repairing a thermoplastic composite material is disclosed herein. The method includes placing an energy transmission material on a supporting anvil, placing the thermoplastic composite material on top of the energy transmission material, and applying an ultrasonic welder to the energy transmission material to consolidate and repair the thermoplastic composite material.

placing an energy transmission material on a supporting anvil;
placing the thermoplastic composite material on top of the energy transmission material, the thermoplastic composite material including at least one of delamination, a single edge damage, or a plural edge damage; and
applying an ultrasonic welder to the energy transmission material to consolidate and repair the thermoplastic composite material.
2 . The method of claim 1 , further comprising:
creating the energy transmission material including a soft plastic and/or an elastomer.
3 . The method of claim 2 , wherein the creating the energy transmission material further comprises:
forming a matrix of an elastomeric material; and
forming a fiber reinforcement in the matrix of the elastomeric material.
4 . The method of claim 2 , wherein the creating the energy transmission material further comprises forming a plurality of layers including:
forming a first layer of the plurality of layers;
forming a second layer of the plurality of layers on the first layer; and
forming a third layer of the plurality of layers on the second layer.
5 . The method of claim 4 , wherein at least one of the plurality of layers includes a flexible elastomeric material.
6 . The method of claim 4 , wherein the at least one of the plurality of layers includes a rigid material.
7 . The method of claim 1 , wherein the energy transmission material is a flexible body.
