This review treats the panel as a coupled material\u2013structure\u2013interface\u2013process system rather than ranking core topology in isolation. A scoping-review workflow was updated to 24 July 2026 and yielded a curated evidence corpus of 112 total references. The review reports the search and screening logic explicitly, uses descriptive rather than field-wide bibliometric claims, and organizes the synthesis around component roles, governing mechanisms, connection regions, performance requirements and application-driven selection. Conventional foam, honeycomb and corrugated cores are compared with lattice-truss, auxetic, origami\/kirigami, hierarchical, bio-inspired, graded and triply periodic minimal-surface (TPMS) architectures. Particular emphasis is placed on face-core and nodal junctions, static and dynamic failure-mode competition, fatigue and environmental degradation, fire\/thermal\/acoustic functions, additive-manufacturing defects, modelling fidelity, and active\/adaptive concepts using shape-memory alloys and piezoelectric actuation. Cross-study numerical envelopes that could not be traced to harmonized test conditions are not used as universal rankings; instead, a mechanism-based screening matrix identifies design strengths, limitations and reporting requirements. The synthesis indicates that engineering deployment depends on preserving intended load paths in the as-manufactured panel, controlling interfaces and defects, validating multi-hazard durability and connections at scale, and integrating multifunctional or adaptive functions without creating new weak links.<\/jats:p>","DOI":"10.3390\/ma19173659","type":"journal-article","created":{"date-parts":[[2026,8,31]],"date-time":"2026-08-31T04:24:03Z","timestamp":1788150243000},"page":"3659","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Lightweight and High-Strength Sandwich Panels: Materials, Core Architectures, Manufacturing, Mechanical Performance, Multifunctionality and Future Perspectives"],"prefix":"10.3390","volume":"19","author":[{"given":"Yuxin","family":"Tang","sequence":"first","affiliation":[{"name":"School of Civil Engineering, Chongqing University, Chongqing 400045, China"},{"name":"Key Laboratory of New Technology for Construction of Cities in Mountain Area, Chongqing University, Chongqing 400045, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi","family":"Song","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Chongqing University, Chongqing 400045, China"},{"name":"Key Laboratory of New Technology for Construction of Cities in Mountain Area, Chongqing University, Chongqing 400045, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiang","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Chongqing University, Chongqing 400045, China"},{"name":"Key Laboratory of New Technology for Construction of Cities in Mountain Area, Chongqing University, Chongqing 400045, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianhao","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Chongqing University, Chongqing 400045, China"},{"name":"Key Laboratory of New Technology for Construction of Cities in Mountain Area, Chongqing University, Chongqing 400045, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4049-1468","authenticated-orcid":false,"given":"Yifeng","family":"Zhong","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Chongqing University, Chongqing 400045, China"},{"name":"Key Laboratory of New Technology for Construction of Cities in Mountain Area, Chongqing University, Chongqing 400045, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaopu","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Chongqing University, Chongqing 400045, China"},{"name":"Key Laboratory of New Technology for Construction of Cities in Mountain Area, Chongqing University, Chongqing 400045, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Allen, H.G.
