Additive Manufacturing of Gradient Stiffness Honeycombs Using Thermoplastic Polyurethane Composite Material Variations

Advanced Engineering Materials, EarlyView.
By combining porous, solid, and carbon fiber‐reinforced thermoplastic polyurethane within a single 3D printed honeycomb structure, this current work achieved precise control over spatial stiffness while ensuring strong interlayer adhesion. The findings demonstrate enhanced energy absorption and densification strain, outperforming traditional uniform ...

Bioinspired Materials, Designs, and Manufacturing Strategies for Advanced Impact‐Resistant Helmets

Advanced Engineering Materials, EarlyView.
This review explores how bioinspired materials, structures, and manufacturing strategies transform helmet design to achieve enhanced impact resistance. Drawing inspiration from nacre, porcupine quills, beetle exoskeletons, and skull architectures, it highlights advances in auxetic lattices, nanocomposites, and functionally graded foams.

Is Young's Modulus a Critical Coating Property Determining Fouling‐Release Performance of Marine Coatings?

Advanced Engineering Materials, EarlyView.
The release of foulers from protective marine coatings is determined by several interrelated material properties, including the strength of Young's modulus, the flexibility of chain segments, the surface free energy, and the magnitude of hydrodynamic stress.

Development of SiC Nanocomposites Using Direct Ink Writing Process

Advanced Engineering Materials, EarlyView.
Herein, feedstock inks containing polycarbosilane and various concentrations of SiC nanoparticles (SiCnp) are investigated for fabricating ceramic matrix composites using a DIW 3D printing process. Characterization results from physical measurement, microstructure analysis, and thermal and flexural testing suggested that high‐performance CMC samples ...
