Abstract: The present disclosure relates to a novel method of laser-based fabrication of a carbon nanotube (CNT)-metal composite on a flexible substrate, and the fabricated CNT-metal composite that is bonded with the flexible substrate, and that has a high electrical conductivity, and that has a longer bending-fatigue life than the laser-sintered metal of the same type without CNTs onto the flexible substrate.

Abstract: Processes and systems that include one or more laser beam sources configured to provide laser irradiation with one or more laser pulse groups to at least a portion of powder particles on a solid surface at one or multiple locations thereof. Sintering laser pulse(s) is provided to induce coalition of at least some of the powder particles into a more continuous medium, and pressing laser pulse(s) is provided to produce pressure pulse(s) on at least a portion of the powder particles and/or the more continuous medium. Laser pulse groups may include one or more of the sintering laser pulses followed by one or more of the pressing laser pulses with a time delay between a last of the sintering laser pulse(s) and a first of the pressing laser pulse(s).
