Two carbon-fiber-reinforced polymer (CFRP) pre-preg types were tested: 12 plies of unidirectional tape or 8 plies of plain weave fabric for a laminate approximately 1.8 mm thick in both cases. Three stacking sequences were analysed, in order to identify the configuration able to maximize the specific energy absorption (SEA), i.e. the energy absorbed per unit mass of crushed structure is expressed in J/g, with the unidirectional specimen providing the best results. In order to have a controlled crush, the specimens were produced with different auto-triggering configurations. Indeed, the fibers' continuity was interrupted in selected position and to different degrees in order to investigate the SEA of the weakened laminates. For unidirectional specimens, the SEA maximum value and behaviour over the stroke were unaffected by the trigger position. Therefore, the auto-triggering configuration was able to control the position of the initial failure of the specimen without any decrease in safety performance"},{"@xml:lang":"sl","#text":"Namen snovanja za odpornost pri trku je preučevanje sposobnosti konstrukcij, da absorbirajo energijo: nadzorovan in postopen kolaps delov vozila zagotavlja varno disipacijo zadostne količine kinetične energije v primeru trka. Energijo tradicionalno in še posebej pri letalih absorbirajo kovinski deli, ki se porušijo nadzorovano in se pri tem intenzivno plastično preoblikujejo. Nadomeščanje kovin s kompoziti, zlasti z epoksidnimi smolami, ojačenimi z ogljikovimi vlakni, lahko izboljša učinkovitost absorpcije energije. Manjkajo pa podatki o odzivu teh konstrukcij pri delovnih obremenitvah, in še posebej v primeru trka. Numerični modeli, podprti s testi na vzorcih in manjših konstrukcijah, so prednostna izbira za preučevanje tega vedenja"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:doc-G9Z7LVLP","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-G9Z7LVLP"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-G9Z7LVLP/4c51d3c0-7999-4296-88f4-d8ae557276a0/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-G9Z7LVLP/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-G9Z7LVLP"}}}}
