MİKRO BOYUTLU GENLEŞTİRİLMİŞ PERLİT VE ALÜMİNYUM HİDROKSİT TAKVİYELİ EPOKSİ KOMPOZİTLERİN MEKANİK VE MİKROYAPISAL ANALİZİ

Öz

Bu çalışma, mikro boyutlu genleştirilmiş perlit ve alüminyum hidroksit dolgu maddeleriyle güçlendirilmiş epoksi kompozitlerin mekanik özelliklerini ve mikro yapısını araştırmaktadır. Dolgu maddesi içeriğinin performansa etkilerini değerlendirmek için ASTM standartlarına göre çekme ve basma testleri yapılmıştır. Saf epoksi numunesi 5,04 MPa çekme dayanımı sergilemiştir. Mineral bazlı dolgu maddeleri mekanik davranışı iyileştirmiştir. %5 ağırlık oranında genleştirilmiş perlit ve %5 ağırlık oranında alüminyum hidroksit içeren hibrit kompozitte çekme dayanımı 6,39 MPa'ya yükselirken, %10 ağırlık oranında genleştirilmiş perlit ve %10 ağırlık oranında alüminyum hidroksit içeren kompozitte en yüksek çekme dayanımı olan 6,93 MPa elde edilmiştir. Basma dayanımı özelliklerinde de benzer iyileşmeler gözlemlenmiştir. Saf epoksinin 63,82 MPa olarak ölçülen basma dayanımı, %5 ağırlık oranında genleştirilmiş perlit ve %5 ağırlık oranında alüminyum hidroksit içeren hibrit kompozitte 84,21 MPa'ya yükselmiştir. Maksimum basma dayanımı, %10 ağırlık oranında alüminyum hidroksit ile güçlendirilmiş kompozitte 85,62 MPa olarak elde edilmiştir. SEM analizleri, dolgu maddesinin epoksi matris içindeki dağılımını ve arayüzey bağlama kalitesini doğrulamıştır. Bununla birlikte, daha yüksek dolgu maddesi içeriklerinde partikül kümelenmesi gözlemlenmiş ve bu durumun mekanik performansı olumsuz etkilediği görülmüştür. Genel olarak, dolgu maddesi oranı ve homojen dağılımın kompozit performansını iyileştirmede önemli parametreler olduğu anlaşılmıştır.

This study investigates the mechanical properties and microstructure of epoxy composites reinforced with micro-sized expanded perlite and aluminum hydroxide fillers. Tensile and compressive tests were conducted according to ASTM standards to evaluate the effects of filler content on performance. The pure epoxy sample exhibited a tensile strength of 5.04 MPa. Mineral-based fillers improved mechanical behavior. The tensile strength increased to 6.39 MPa in the hybrid composite containing 5 wt.% expanded perlite and 5 wt.% aluminum hydroxide, while the highest tensile strength of 6.93 MPa was achieved in the composite containing 10 wt.% expanded perlite and 10 wt.% aluminum hydroxide. Similar improvements were observed in compressive properties. The compressive strength of pure epoxy, measured as 63.82 MPa, increased to 84.21 MPa in the hybrid composite containing 5 wt.% expanded perlite and 5 wt.% aluminum hydroxide. The maximum compressive strength, 85.62 MPa, was obtained in the composite reinforced with 10 wt.% aluminum hydroxide. SEM analyses confirmed filler distribution within the epoxy matrix and confirmed interfacial bonding quality. However, particle agglomeration was observed at higher filler contents and may adversely affect mechanical performance. Overall, it was understood that filler ratio and homogeneous distribution are important parameters in improving composite performance.
