Abstract
This study explores direct ink writing (DIW) 3D printing for fabricating ultralight biomimetic helical carbon fiber composites. Composites with varying interlaminar angles (0°-40°) were compared to mold-formed samples in terms of tribological performance. The DIW method improved fiber orientation and interfacial bonding, significantly enhancing mechanical and wear properties. A 10° helical angle yielded over 50 % reductions in both friction coefficient and wear rate, along with high hardness and modulus. The printed composite achieved ultralow density (0.467 g/cm³) while maintaining structural integrity. These findings demonstrate the potential of DIW-fabricated helical composites for lightweight, durable applications in aerospace, automotive, and other high-performance engineering fields.
期刊介绍：
Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International.
Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
