Designing the microstructural architecture of bioinspired hierarchical hybrid nanocomposites
Abstract
This study focuses on investigating the microstructural architecture of bioinspired hierarchical graphene nanoplatelets-(GnPs) and glass fiber-(GF) reinforced polypropylene-based hybrid composites and its impact on mechanical performance. A novel approach to control the self-assembly behavior of hierarchically structured fibrous reinforcements is presented, achieved by tailoring the surface chemistry of the GFs to optimize the density of covalently bonded GnPs. Structure-property relationships were established by comparing the GnP bonding density on the GFs and degree of trans-crystallization as a function of amino-surface modification with the mechanical performance of the fabricated composites. Tailoring the microstructural architecture can significantly improve the mechanical properties of these hybrid composites, due to improved stress transfer at the interface. This improvement arises from the increased interfacial area of the hierarchically structured hybrid reinforcement, which facilitates trans-crystalline growth at the interface. Additionally, the remaining un-bonded GnPs facilitate β-crystal nucleation in the bulk, improving the composite’s toughness. The hybrid composite with the highest GnP bonding density and the greatest degree of trans-crystallization demonstrates exceptional mechanical performance. Specifically, this hybrid composite exhibits an impact strength of ~ 63% greater than that without hierarchical reinforcement, along with tensile strength and toughness improvements of ~ 40% and ~ 77%, respectively.
期刊介绍:
Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field.
The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest.
Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials.
Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
