Kompozit malzemeler, gelişen teknoloji ile birlikte günümüzde birçok alanda başarıyla kullanılmaktadırlar. Elyaf takviyeli polimer kompozitler, yüksek dayanım ve düşük maliyet özelliklerinden dolayı en sık tercih edilen kompozit malzemelerdir. Cam elyaf takviyeli polyester (CTP) kompozitler kullanım alanlarına göre istenilen mekanik ve tribolojik özellikleri karşılayan polimer matrisli ve cam elyaf takviye malzemeli bir kompozit türüdür. Cam elyaf takviyeli polyester kompozit malzemeler farklı türlerde polyester ve çekme katkıları içerebilmektedir. Çevresel koşullar cam elyaf takviyeli polyester kompozitlerin aşınma dayanımı üzerinde etkili olmaktadır. Bu çalışmada, iki farklı türde polyester (ortoftalik ve izoftalik) ve çekme katkısı (polistiren ve plastifiyen) içeren cam elyaf takviyeli polyester kompozit malzemelerin farklı çevresel koşullar (UV ışıma, asit ortamı, tuzlu su ortamı, hızlandırılmış yaşlandırma, hidrotermal yaşlandırma ve termal çevrim) altındaki aşınma davranışları incelenmiş ve farklı türlerde polyester ve çekme katkısı içeren numunelerde çevresel koşulların malzemelerin aşınma davranışları üzerine olan etkileri araştırılmıştır. CTP kompozit numunelerin aşınma dayanımına çevresel koşulların etkileri dikkate alındığında her iki numunede de UV ışıma ortamına ve hidrotermal yaşlandırmaya maruz kalan numunelerin aşınma dayanımının arttığı gözlemlenmiştir. CTP kompozit malzemelerin içerisinde polistiren çekme katkısının kullanılması malzemenin aşınma dayanımını iyileştirmektedir. Ortoftalik polyester reçine içeren CTP kompozit numunelerin, izoftalik reçine içeren numunelere kıyasla aşınma dayanımları daha iyidir.

Investigation of the Effects of Environmental Conditions on Wear Behaviors in Glass Fiber Reinforced Polyester Composite Materials Containing Different Types of Polyester and Low Profile Additive

Composite materials are used successfully in many fields today with the developing technology. Fiber reinforced polymer composites are the most preferred composite materials due to their low cost properties and high strength. Glass fiber reinforced polyester (GFRP) composites are a type of composite with polymer matrix and glass fiber reinforcement material that meet the desired mechanical and tribological properties according to their usage areas. GFRP composite materials can contain different types of polyester and shrinkage additives. Environmental conditions affect the wear resistance of glass fiber reinforced polyester composites. In this study, different environmental conditions (UV irradiation, acid environment, salt water environment, accelerated aging, hydrothermal aging and thermal cycling) of glass fiber reinforced polyester composite materials containing two varied types of polyester (orthophthalic and isophthalic) and low profile additive (polystyrene and plasticizer) were investigated and the effects of environmental conditions on the wear behavior of the materials were investigated in samples containing different types of polyester and low profile additives. Considering the effects of environmental conditions on the wear resistance of the GFRP composite samples, it was observed that the wear resistance of the samples exposed to UV irradiation and hydrothermal aging increased in both samples. The use of polystyrene low profile additive in GFRP composite materials increases the wear resistance of the material. GFRP composite samples containing orthophlalic polyester resin have better wear resistance than samples containing isophlalic resin.
