Unfortunately, its use is still restricted to traditional areas, with the agglomerate form in particular not being used to its full potential. The objective of this article is to analyze the viability of using cork-based material as core materials in sandwich structures in aeronautical and aerospace applications. The use of cork-based material is proposed because of its isolation properties (both thermal and acoustic) and there is no significant performance loss, when compared with the currently used materials. It presents other advantages, as well as, less wastage of energy in manufacturing and a better environmental integration, both in the transformation stage and in the end of life recycling stage. The objective of this work is to study the mechanical behavior of different sandwich specimens, with carbon\/epoxy faces, and cores of different cork agglomerates and their comparison with the results obtained with similar specimens using current material cores. Experimental shear tests and three-point bending tests were carried out and the evolutions of the load\u2014 displacement curves of the different cork agglomerates\/sandwiches were analyzed and discussed. The obtained results show that significant room for improvement still exists in use of cork-based core materials.<\/jats:p>","DOI":"10.1177\/1099636209104523","type":"journal-article","created":{"date-parts":[[2009,6,5]],"date-time":"2009-06-05T20:31:54Z","timestamp":1244233914000},"page":"487-500","source":"Crossref","is-referenced-by-count":54,"title":["Mechanical Behavior of Sandwich Structures using Natural Cork Agglomerates as Core Materials"],"prefix":"10.1177","volume":"11","author":[{"given":"L.","family":"Reis","sequence":"first","affiliation":[{"name":"Instituto Superior T\u00e9cnico, Departamento Engenharia Mec\u00e2nica, Universidade T\u00e9cnica de Lisboa Avenida Rovisco Pais, 1049-001 Lisboa, Portugal,"}]},{"given":"A.","family":"Silva","sequence":"additional","affiliation":[{"name":"Instituto Superior T\u00e9cnico, Departamento Engenharia Mec\u00e2nica, Universidade T\u00e9cnica de Lisboa Avenida Rovisco Pais, 1049-001 Lisboa, Portugal"}]}],"member":"179","published-online":{"date-parts":[[2009,6,5]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1016\/S0266-3538(03)00294-X"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.1016\/S0263-8223(03)00028-X"},{"key":"atypb3","volume-title":"The Handbook of Sandwich Construction","author":"Zenkert, D.","year":"1997"},{"key":"atypb4","volume-title":"Estudo Experimental e Anal\u00edtico, em Compress\u00e3o, de Diferentes Espumas para Aplicac\u00e3o em Construc\u00e3o Sandwich","author":"Leite, M.","year":"2005"},{"key":"atypb5","volume-title":"Standard Test Method for Shear Properties of Sandwich Constructions","author":"ASTM C 273.","year":"2000"},{"key":"atypb6","doi-asserted-by":"publisher","DOI":"10.1520\/JTE11121J"},{"key":"atypb7","volume-title":"Shearing Testing of Sandwich Panel Core Materials","author":"Adams, D.F.","year":"2007"},{"key":"atypb8","doi-asserted-by":"publisher","DOI":"10.1016\/S1359-835X(01)00110-5"},{"key":"atypb9","volume-title":"Standard Test Method for Flexural Properties of Sandwich Constructions","author":"ASTM C 393.","year":"2000"},{"key":"atypb10","volume-title":"Analysis and Design of Structural Sandwich Panels","author":"Allen, H.G.","year":"1969"},{"key":"atypb11","doi-asserted-by":"publisher","DOI":"10.1016\/S0263-8223(97)80007-4"}],"container-title":["Journal of Sandwich Structures &amp; Materials"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1099636209104523","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1099636209104523","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T05:42:41Z","timestamp":1777527761000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1099636209104523"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,6,5]]},"references-count":11,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2009,11]]}},"alternative-id":["10.1177\/1099636209104523"],"URL":"https:\/\/doi.org\/10.1177\/1099636209104523","relation":{},"ISSN":["1099-6362","1530-7972"],"issn-type":[{"value":"1099-6362","type":"print"},{"value":"1530-7972","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,6,5]]}}}
