Synergistic enhancement effect of flame-grown carbon nanotubes and chopped carbon fibers on adhesive joint of thermosetting laminate

Xuhai Xiong et al.

Summary: The study investigates the cross-scale combination of carbon nanotubes and chopped carbon fibers as an enhancer for adhesive in thermoset composite bonded joints. The composites reinforced with the combination of CNTs and CCFs show higher strength, with over 30.8% improvement compared to composites reinforced solely with CCFs.

Fused Filament Fabrication 3D printed polypropylene/alumina nanocomposites: Effect of filler loading on the mechanical reinforcement

Nectarios Vidakis et al.

Summary: In this study, three-dimensional printed polypropylene reinforced with aluminum oxide nanoparticles was developed and characterized. The addition of alumina nanoparticles significantly improved the mechanical properties of the composite, including tensile, flexural, and thermomechanical properties. This material shows great potential for various engineering applications where enhanced static and dynamic mechanical properties are required.

Effect of Recovered Silicon Filler Inclusion on Mechanical and Tribological Properties of Polytetrafluoroethylene (PTFE) Composite

K. Vishal et al.

Summary: This study investigated the effect of recovered silicon fine wafer fillers on the friction behavior of PTFE matrix. The addition of 5 wt% silicon filler significantly increased the hardness of PTFE composite, while reducing the friction coefficient and specific wear rate. However, silicon concentration beyond 3% did not greatly improve the anti-friction performance of PTFE/Silicon composite.

Revalorization of Australian royal palm (Archontophoenix alexandrae) waste as reinforcement in acrylonitrile butadiene styrene (ABS) for use in 3D printing pen

Alessandra M. S. Marton et al.

Summary: This study evaluates the potential use of palm residues as reinforcement in acrylonitrile butadiene styrene (ABS) matrix to develop a more environmentally friendly composite filament. The effect of fiber contents on morphological, chemical, and thermal properties is investigated, and a life cycle assessment is performed to analyze the environmental impact. The study demonstrates that the inclusion of fibers has beneficial effects on the environment, especially in terms of agricultural land occupation and ozone depletion. The feasibility of using the developed filaments in 3D printing is also proven, suggesting new applications in the additive manufacturing field.
