Abstract
Lattice structures, produced by repeated unit cells in the particular pattern, offer a high strength-to-weight ratio. The current advancement in Additive manufacturing (AM) technology, creating complex geometries like lattice structures has revolutionized production across various industries. While several reviews have focused on different specific aspects of lattice structures, a comprehensive overview of recent advancements of lattice in aerospace structural applications is lacking.
Therefore, a comprehensive review of lattice structures used in aerospace lightweight applications manufactured through AM is presented here. Basic classification of lattice structure is presented followed by detailed study of several factors influencing mechanical properties of lattice structures, crucial for aerospace lightweight application. Current trends in manufacturing technologies of lattice structures are analyzed in detail with identification of capabilities and limitations. Furthermore, detailed literature on the lattice structure optimization techniques is presented with current limitations. Furthermore, the engineering applications of lattice structures in aerospace lightweight, along with the fabrication processes involved, challenges in applications of lattice in aerospace applications and future research directions are reported.
By providing insights into current research trends and future directions, this review serves as a valuable resource for researchers and engineers involved in the design and development of lightweight aerospace lattice structures. It lays the groundwork for the exploration of new and innovative lattice structures tailored to meet the evolving needs of the aerospace industry.
晶格结构由特定图案中的重复单元格产生，具有很高的强度重量比。目前，增材制造（AM）技术的发展，创造出了复杂的几何形状，如晶格结构，为各行各业的生产带来了革命性的变化。虽然有几篇综述侧重于格子结构的不同具体方面，但缺乏对格子结构在航空航天结构应用中最新进展的全面概述。因此，本文对通过 AM 制造的用于航空航天轻质应用的格子结构进行了全面综述。本文介绍了晶格结构的基本分类，随后详细研究了影响晶格结构力学性能的几个因素，这些因素对航空航天轻量化应用至关重要。还详细分析了格子结构制造技术的当前趋势，并确定了其能力和局限性。此外，还介绍了有关晶格结构优化技术的详细文献以及当前的局限性。此外，还报告了格子结构在航空航天轻量化中的工程应用，以及所涉及的制造工艺、格子在航空航天应用中面临的挑战和未来的研究方向。通过对当前研究趋势和未来方向的深入分析，本综述为从事轻量化航空航天格子结构设计和开发的研究人员和工程师提供了宝贵的资源。它为探索新的创新晶格结构奠定了基础，以满足航空航天工业不断发展的需求。
