Dual-matrix interface strength of 3D printed continuous carbon fiber reinforced composites: Quantitative assessment methodology and critical influencing factors

Additive Manufacturing Letters
In 3D printed continuous carbon fiber reinforced dual-matrix composites, the resin matrix in the carbon fiber prepreg filament is not the same with the matrix in the composite, and the dual-matrix interface plays an important role on the mechanical ...

Effect of Laser Deoxidation on Adhesive‐Bonded Aluminum in an Oxygen‐Free Atmosphere

Advanced Engineering Materials, EarlyView.
This study investigates laser ablation of aluminum under oxygen‐free conditions. The goal is to produce oxide‐free substrates that enable improved adhesive bonding with epoxy. Optimized laser parameters (90% overlap, 300 µJ) combined with oxide‐free substrates result in the highest tensile strength of the adhesive bond.
