Atık oyuncakların geri dönüşüm malzemesi olarak cam-elyaf fiber takviyeli kompozitlerde kullanımlarının mekanik özelliklere etkisinin araştırılması

Öz

Bu çalışmanın amacı, eski oyuncakları geri dönüştürerek fiber kompozit malzeme elde etmektir. Bu amaçla, atık oyuncaklar önce toplanmış ve temizlenmiştir. Oyuncak parçaları daha sonra erimesi ve sertleşmesi için ısıya maruz bırakılmıştır. Sertleşen parçalar daha sonra öğütülerek toz dolgu malzemesi haline getirilmiştir. Bu dolgu malzemesi farklı oranlarda epoksiye eklenerek kompozit malzemeler elde edildi. Bu malzemelerin mukavemet değerleri deneysel olarak ölçüldü. Sonuç olarak elde edilen veriler, atık oyuncakların ısıl işlem sonrası mikro boyuta getirilerek cam elyaf fiber takviyeli kompozitlere dolgu malzemesi olarak katkısı kademeli olarak mekanik özellikleri düşürmektedir. Ağırlıkça % 2 oranında atık oyuncak tozunun ilavesi katkılı diğer kompozitlere göre mekanik özellikler açısından en iyi sonuçları vermektedir. Bu da, düşük tanecik boyutlu atık oyuncakların dolgu malzemesi olarak fiber takviyeli kompozitlerde dolgu malzemesi olarak kullanılmasının sürdürülebilir malzeme kullanımı ve atık yönetimi açısından önemli bir rol oynadığını göstermektedir.

Investigation of the effect of the use of waste toys as recycling material in glass-fiber reinforced composites on mechanical properties

Öz

The aim of this study is to obtain fiber composite material by recycling old toys. For this purpose, waste toys were first collected and cleaned. The toy parts were then exposed to heat to melt and harden. The hardened pieces were then ground into powder filler material. This filler material was added to epoxy at different ratios to obtain composite materials. The strength values of these materials were measured experimentally. The data obtained as a result shows that the addition of waste toys as filler material to glass fiber reinforced composites by bringing them to micro size after heat treatment gradually decreases the mechanical properties. The addition of 2 wt% of waste toy powder gives the best results in terms of mechanical properties compared to other doped composites. This shows that the use of low particle size waste toys as fillers in fiber reinforced composites plays an important role in sustainable material use and waste management.
