DENİZ SUYU KOROZYON ORTAMINDA BAZALT/EPOKSİ KOMPOZİTLERİN MEKANİK DAVRANIŞLARININ İNCELENMESİ

Özet

Epoksi matrisli elyaf takviyeli kompozitler yüksek dayanım ve rijitliklerinden dolayı ileri teknoloji ürünleri olarak endüstride yaygın kullanılmaktadır. Son zamanlarda kullanım sahasının genişliği, yüksek dayanım ve rijitlik, korozyon direnci, gürültü, titreşim ve ısıl yalıtım özelliklerinin iyi olması ve maliyetinin karbon elyaflardan düşük olması nedeniyle, elyaf takviye malzemesi olarak kompozitlerde bazalt elyaflar tercih sebebi olmuştur. Dolayısıyla araştırmacılar bazalt elyaf takviyeli kompozitler ile ilgili çalışmalara yönlenmişlerdir. Yapılan çalışmada, vakum infüzyon yöntemi ile 6 tabakalı bazalt elyaf takviyeli (BTP) epoksi kompozit levhalar üretilmiştir. Üretilen bu levhalardan çekme numuneleri ASTM D 3039/D 3039M standartlarına uygun olarak hazırlanmış ve Akdeniz suyu korozyon ortamında 0, 10, 20 ve 40 gün sürelerinde bekletildikten sonra çekme deneyleri gerçekleştirilmiştir. Artan deniz suyu korozyon sürelerine göre çekme dayanımlarındaki % azalmalar tespit edilmiştir. 40 gün deniz suyu ortamında bekletilen BTP/Epoksi kompozitlerin çekme dayanımında %26.5’lik kaybın olduğu tespit edilmiştir.

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.
