Abstract
Complex microstructures are the hallmark of natural ceramic biocomposites, but limited processing methods to reproduce them hinder the understanding of mineral orientation roles on the mechanical properties. This study investigates the influence of microplatelet orientation in composite materials, utilizing the magnetically assisted direct ink writing method (M-DIW) to create microstructured microplatelet-reinforced composites. Experimental and computational approaches are employed to explore the critical role of microplatelet orientation on the flexural properties of these materials. Horizontal microplatelets are found to significantly enhance the composite’s flexural toughness by promoting overlap and increasing fracture energy during crack propagation. Vertical microplatelets contribute to increased flexural modulus and strength. Perpendicular microplatelets facilitate straight crack paths and smoother fracture surfaces. Moreover, complex microstructural designs were introduced by strategically combining microplatelet orientations to optimize mechanical properties. These findings emphasize the vital role of microplatelet orientation in composite materials, offering potential for tailored materials with superior performance.
Impact statement
The findings of this research carry significant implications in the fields of materials science and engineering. By comprehensively examining the role of microplatelet orientation in composite materials, this study offers a novel perspective on how to optimize mechanical properties for various applications. The identification of distinct strengths and limitations associated with horizontal, vertical, and perpendicular microplatelet orientations enables the creation of tailored materials with enhanced mechanical performance. This customization potential holds considerable promise for industries that rely on composite materials, such as aerospace, automotive, and construction. Moreover, the introduction of hierarchical designs presents innovative avenues for engineering materials with superior properties. These designs showcase the potential to achieve a delicate balance between flexural toughness, strength, and modulus, allowing for materials that can outperform traditional monolithic structures. Ultimately, this research empowers materials scientists and engineers to make informed decisions regarding microplatelet orientation, enhancing the efficiency and versatility of composite materials across a wide range of industries. As a result, it brings us one step closer to a future where materials can be precisely tailored to meet the demands of specific applications, driving innovation and progress in diverse sectors.
