Abstract
This study investigates the effects of seawater exposure on the crashworthiness of two types of carbon/epoxy composite tubes under quasi-static compression. Carbon/epoxy composites, widely used in maritime structures due to their high strength-to-weight ratio and corrosion resistance, may experience altered mechanical properties when exposed to harsh marine conditions. To evaluate these effects, quasi-static crushing tests were conducted on composite tubes after a one-month exposure to natural seawater. Composite tubes were manufactured using hand layup and prepreg technique. By analyzing the behavior of these composite structures under controlled compression, the study aims to provide insights into their structural integrity in marine environments. Results indicate a significant impact of seawater exposure on the crashworthiness of carbon/epoxy composites. The maximum compression force is considerably lower after the exposure, and hand layup specimens generally withstand the exposure much better than prepregs. The findings contribute to a deeper understanding of material behavior in marine applications, offering practical guidelines for designing and maintaining composite-based maritime infrastructure.
Abstract (croatian)
Ova studija istražuje učinke izloženosti morskom okolišu na tlačnu čvrstoću dviju vrsta cijevi od ugljika/epoksi kompozita pod kvazistatičkom kompresijom. Ugljik/epoksidni kompoziti, naširoko korišteni u pomorskim strukturama zbog visokog omjera čvrstoće i težine i otpornosti na koroziju, mogu doživjeti izmijenjena mehanička svojstva kada su izloženi teškim morskim uvjetima. Kako bi se procijenili ti učinci, provedena su kvazistatička ispitivanja drobljenja na kompozitnim cijevima nakon jednomjesečnog izlaganja prirodnoj morskoj vodi. Kompozitne cijevi proizvedene su tehnikom ručnog laminiranja i preprega. Analizom ponašanja ovih kompozitnih struktura pod kontroliranom kompresijom, studija ima za cilj pružiti uvid u njihov strukturni integritet u morskom okruženju. Rezultati pokazuju značajan utjecaj izloženosti morskoj vodi na otpornost ugljika/epoksi kompozita na udar. Maksimalna sila kompresije znatno je niža nakon izlaganja, a uzorci izrađeni ručnom laminacijom općenito podnose izlaganje mnogo bolje od preprega. Rezultati pridonose dubljem razumijevanju ponašanja materijala u pomorskim primjenama, nudeći praktične smjernice za projektiranje i održavanje pomorske infrastrukture temeljene na kompozitima.
