DENIZ SUYU KOROZYON ORTAMINDA BAZALT/EPOKSI KOMPOZITLERIN MEKANIK DAVRANISLARININ INCELENMESI Ozet Epoksi matrisli elyaf takviyeli kompozitler yuksek dayanim ve rijitliklerinden dolayi ileri teknoloji urunleri olarak endustride yaygin kullanilmaktadir. Son zamanlarda kullanim sahasinin genisligi, yuksek dayanim ve rijitlik, korozyon direnci, gurultu, titresim ve isil yalitim ozelliklerinin iyi olmasi ve maliyetinin karbon elyaflardan dusuk olmasi nedeniyle, elyaf takviye malzemesi olarak kompozitlerde bazalt elyaflar tercih sebebi olmustur. Dolayisiyla arastirmacilar bazalt elyaf takviyeli kompozitler ile ilgili calismalara yonlenmislerdir. Yapilan calismada, vakum infuzyon yontemi ile 6 tabakali bazalt elyaf takviyeli (BTP) epoksi kompozit levhalar uretilmistir. Uretilen bu levhalardan cekme numuneleri ASTM D 3039/D 3039M standartlarina uygun olarak hazirlanmis ve Akdeniz suyu korozyon ortaminda 0, 10, 20 ve 40 gun surelerinde bekletildikten sonra cekme deneyleri gerceklestirilmistir. Artan deniz suyu korozyon surelerine gore cekme dayanimlarindaki % azalmalar tespit edilmistir. 40 gun deniz suyu ortaminda bekletilen BTP/Epoksi kompozitlerin cekme dayaniminda %26.5’lik kaybin oldugu tespit edilmistir.

INVESTIGATION OF MECHANICAL BEHAVIOURS OF BASALT/EPOXY COMPOSITES IN SEA WATER CORROSION ENVIRONMENT Abstract Fiber reinforced composites based on epoxy matrix because of their high strength and stiffness as advanced technology products have been used widely in the industry. In recently, basalt fibers have been the preferred fiber reinforcement material in composites because of the wide area of use, high strength and rigidity, good corrosion resistance, noise, vibration and thermal insulation properties and low cost of carbon fibers. Therefore, researchers are directed to work on basalt fiber reinforced composites. In this study, 6 layered basalt fiber reinforced (BTP) epoxy composite sheets were produced by vacuum infusion method. Tensile specimens were prepared from these sheets in accordance with ASTM D 3039/D 3039M standard and tensile tests were carried out after 0, 10, 20 and 40 days in Mediterranean water corrosion environment. % losses in tensile strengths were determined according to the increasing sea water corrosion periods. It has been determined that the tensile strength of BTP/Epoxy composites kept in sea water environment for 40 days is 26.5% loss. Keywords: Basalt fibers, Composites, Corrosion, Mechanical Properties.
