Povzetek

Tehnične tkanine so zaradi mnogoterih lastnosti pomembne v številnih panogah. Namen te raziskave je bil uporabiti pletene kompozitne palice za ojačitev betonskih nosilcev. Pletene vrvice, izdelane iz polipropilenskih prej v zunanji plasti in jedra iz združenih prej, so bile potopljene v lokalno dostopno epoksi smolo Kemapoxy 150. Izdelanih je bilo šest vzorcev pletenih kompozitnih palic iz dveh polipropilenskih prej različne dolžinske mase in tremi različnimi jedri. Opravljenih je bilo več testiranj pletenih vrvic in pletenih kompozitnih palic. Vse meritve so bile statistično analizirane (ANOVA) in prikazane s pomočjo polarnih grafikonov. Izdelani so bili trije betonski nosilci z eno, dvema oziroma tremi pletenimi kompozitnimi palicami. Rezultati so pokazali, da različne preje v zunanji plasti in jedru pomembno vplivajo na lastnosti pletenih vrvic in pletenih kompozitnih palic. Pletene kompozitne palice z jedrom iz polipropilenske preje so primerne za betonske nosilce, ki ne zahtevajo velikih obremenitev. Pletene kompozitne palice iz steklenih vlaken oziroma iz 50-odstotkov polipropilenskih in 50-odstotkov polietilenskih vlaken niso primerne za aplikacije, kjer je zahtevana večja upogibljivost in raztegljivost betonskih nosilcev. Pletene kompozitne palice so izboljšale učinkovitost armiranih betonskih nosilcev, pri čemer je bila ugotovljena najvišja upogibna sila pri uporabi dveh palic na betonski nosilec.
