This paper reports the experimental and numerical approaches and results of an investigation on the mechanisms that enable the improved ballistic performance of spaced multi-ply systems. Penetration tests were performed over a range of impact velocities ranging from 200 to 400\u202fm\/s. The results confirmed that the ply gap is beneficial to the energy absorption capability of the systems. This is because the front plies tend to absorb more energy when they are not immediately constrained by the rear plies. During a ballistic event, the gap relieves the reflection of the compressive pulse, prolonging the projectile engagement time with the front plies; on the other hand, the rear plies become increasingly less active in dissipating energy as the gap increases. When the gap is sufficiently widened to avoid any interference between the plies before the failure of the front ply, the responses of the whole system no longer vary. It was also found that the ballistic performance of the spaced systems is influenced by ply thickness, impact velocity, and the stacking order of the ply gap.<\/p>\n<p><a href=\"https:\/\/www.fie.undef.edu.ar\/ceptm\/wp-content\/uploads\/2023\/12\/1-s2.0-S2214914723003264-main.pdf\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" class=\"aligncenter wp-image-5168\" src=\"https:\/\/www.fie.undef.edu.ar\/ceptm\/wp-content\/uploads\/2020\/02\/icono-PDF-1-243x300.png\" alt=\"Descargar archivo pdf\" width=\"75\" height=\"93\" srcset=\"https:\/\/www.fie.undef.edu.ar\/ceptm\/wp-content\/uploads\/2020\/02\/icono-PDF-1-243x300.png 243w, https:\/\/www.fie.undef.edu.ar\/ceptm\/wp-content\/uploads\/2020\/02\/icono-PDF-1.png 310w\" sizes=\"(max-width: 75px) 100vw, 75px\" \/><\/a><strong>Fuente:<\/strong> <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S2214914723003264?via%3Dihub\" target=\"_blank\" rel=\"noopener\"><em>https:\/\/www.sciencedirect.com<\/em><\/a><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Este documento informa sobre los resultados de evaluaciones experimentales y num\u00e9ricas sobre los mecanismos que permiten mejorar el rendimiento bal\u00edstico de los sistemas de tejidos&hellip; <\/p>\n","protected":false},"author":1,"featured_media":13821,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[18,24],"tags":[],"_links":{"self":[{"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=\/wp\/v2\/posts\/13820"}],"collection":[{"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=13820"}],"version-history":[{"count":1,"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=\/wp\/v2\/posts\/13820\/revisions"}],"predecessor-version":[{"id":13823,"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=\/wp\/v2\/posts\/13820\/revisions\/13823"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=\/wp\/v2\/media\/13821"}],"wp:attachment":[{"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=13820"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=13820"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=13820"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
