Abstract

Aim of study: In this study, it was aimed to establish and optimize a production process for engineering thermoplastic composites based on heat treated wood fillers and SMA copolymer.

Material and Methods: As wood material, pine wood (Pinus strobus L.), and as a thermoplastic copolymer material, Styrene Maleic Anhydride (SMA) copolymer were used in this study. Heat treatment was conducted at 212°C for 8 h in an attempt to improve the durability of the wood furnish and the wood flour and SMA compounds were extruded and granulated using a lab-scale grinder. Physical test, mechanical test and morphological tests were calculated.

Main results: The results showed that the highest tensile strength was in the 30 wt.% wood flour/SMA and it has been seen that the positive effect on FMOE,TMOE of heat treated wood flour/SMA. Weak interfacial bonding was observed between the polymer and wood filler from the SEM images of the fractured surfaces of wood flour/SMA composites.

Research highlights: The results from this research indicated the compatibility of the SMA copolymer with the wood flour and the changes in the mechanical strength of the material. Due to limited heat treated wood thermoplastic composite usage in the field of wood engineering, there is a need for more extensive work in the future.

Abstract

Çalışmanın amacı: Bu çalışmada, ısıl işlem odun dolguları ve SMA kompozitleri temelli mühendislik termoplastiklerinin üretim proseslerinin optimizasyonun belirlenmesi amaçlanmaktadır.

Materyal ve Yöntem: Ahşap malzeme olarak veymut çamı, termoplastik kopolimer olarak stiren maleik anhidrit çalışmada kullanılmıştır. Odun donatısının kararlılığını iyileştirmek için 8 saatlik 212°C 'de ısıl işlem metodu uygulandı ve SMA ile odun bileşenleri laboratuvar tipi öğütücüler kullanılarak kalıptan geçirildi. Fiziksel, mekanik ve morfolojik testler ölçüldü.

Sonuçlar: Yapılan çalışmalar sonucu en yüksek çekme direnç değeri %30 odun SMA grubunda ve ısıl işlemli odun unu SMA grubunun eğilmede ve çekmede elastikiyet modülü üzerine pozitif etkisi görülmüştür. Odun unu SMA grubunun kırılmış yüzey SEM görüntülerinden odun dolgusu ile polimer arasında zayıf arayüz bağları gözlemlenmiştir.

Araştırma vurguları: Bu araştırmanın sonuçları, mühendislik malzemesi olan SMA kopolimerinin odun unu ile uyumu ve malzemenin mekanik mukavemetindeki değişiklikleri göstermektedir. Ahşap mühendisliği alanında sınırlı ısıl işlemli odun termoplastik kompozit kullanımı nedeniyle gelecekte daha kapsamlı çalışmalara ihtiyaç vardır.
