Abstract: The present disclosure provides methods and systems for composite-to-metal hybrid bonded structures compromising the laser surface treatment on titanium alloys to promote adhesive bond performance. For example, a computer may be programmed to set a laser path corresponding to a predetermined geometric pattern. A laser may be coupled to the computer and apply a pulsed laser beam to a contact surface of the titanium alloy along the predefined geometric pattern. The laser may generate an open pore oxide layer on the contact surface of the substrate with a thickness of 100 and 500 nm. The open pore oxide layer may have a topography corresponding to the predefined geometric pattern. The topography may contain high degree of open pore structure and promote adhesive bond performance. Adhesive, primer or composite resin matrix may fully infiltrate into the open pore structures. Adhesive and composite laminate may co-cure to form composite-to-titanium hybrid bonded structures.

Abstract: A method is provided for one-step-shape/material-transformation, high—2D/3D/4D-precision, high-efficiency, and scalable in situ 4D additive-subtractive manufacturing of ceramics in aerospace fields. The printed ceramics exhibited a high flame ablation performance with the integration of 2D printing (ALD) and 3D/4D printing of ceramic materials. The proposed paradigm can be extended to other high-temperature materials to build ceramic/metal composite structures.

Abstract: Novel methods for activating and electroplating a non-conductive carbon fiber composite part are provided. An exposed surface of the CFC part is mechanically activated followed by creating a relatively thin nickel strike layer in a controlled electrolytic process. A relatively thicker electrolytic nickel layer is deposited over the strike layer. The electrolytic nickel strike layer and electrolytic nickel layer serve as the foundation to enable deposition of any suitable erosion resistant coating thereon.
