Laser Joining of Different Polymer-metal Configurations: Analysis of Mechanical Performance and Failure Mechanisms
TLDR
In this paper, the authors analyzed the mechanical behavior and failure mechanisms of three polymer-metal configurations: lap, T and Arcan joint configurations, where the metal was locally structured by pulsed laser radiation producing micro-patterns to improve adhesion of the polymeric part.About:

Joining CFRP/Ti stacks by directed energy deposition: Surface topography effects on interface formation and bonding
Yue-Ying Zhou,Fuda Ning +1 more
TL;DR: In this paper , the effects of surface topography on interfacial formation mechanism were investigated by experimental and numerical approaches, and the results showed that the pores dominated interfacial structures in CFRP/Ti stacks without surface patterns, yet physical gaps played a vital role in line/grid-patterned CFRP and Ti stacks.

Laser direct joining of AZ91D thixomolded Mg alloy and amorphous polyethylene terephthalate
TL;DR: In this article, the authors showed that the formation of gas bubbles in a narrow region inside a polyethylene terephthalate (PET) sample adjacent to the interface can be induced by the pressure induced by expansion of these bubbles, which secures tight bonding in the micro size between AZ91D and PET specimens.

Effect of metal micro-structuring on the mechanical behavior of polymer–metal laser T-joints
TL;DR: In this article, the metal was locally structured by pulsed laser radiation producing microscopic patterns on its surface and the opposite side of the micro-structured metal was irradiated by a continuous wave (CW) fiber laser to achieve the mechanical interlock between the two materials.
