Bu çalışmada, Sansevieria Trifasciata (Paşa Kılıcı) bitkisinden elde edilen doğal lifler ve nanosilika katkılı hibrid epoksi kompozitlerin eğilme performansı araştırılmıştır. Çalışmanın ilk aşamasında, doğal lifler enzimatik havuzlama yöntemleri kullanılarak elde edilmiştir. Elde edilen lifler, alkali işlemden geçirilerek epoksi bağlanma kapasiteleri artırılmıştır. Bu aşamanın ardından, lifler uzunlamasına yerleştirilerek epoksi matrise nanosilika tozu ile eklenmiştir. Nanosilika oranı ağırlıkça %3 olarak belirlenmiştir. Ayrıca saf epoksiden referans numuneler üretilmiştir. Çalışma süresince üretilen kompozitlerin mekanik özellikleri ASTM D790 standartlarına uygun olarak üç nokta eğme testleri ile karakterize edilmiştir. Elde edilen sonuçlar, kompozit malzemenin yüksek mukavemet ve elastikiyet özelliklerine sahip olduğunu göstermektedir. Ancak homojen olmayan kırılma davranışları, malzemenin üretim sürecindeki varyasyonlardan kaynaklanabilir. Çalışma, çevresel sürdürülebilirlik ve endüstriyel uygulamalarda doğal kompozitlerin potansiyelini ortaya koymuştur.

Investigation of the Flexural Performance of Hybrid Epoxy Composites Reinforced with Nanosilica/Sansevieria Trifasciata (Snake Plant) Natural Fiber

Öz

In this study, the flexural performance of hybrid epoxy composites reinforced with natural fibers obtained from Sansevieria Trifasciata (Snake Plant) and nanosilica was investigated. In the first stage of the study, natural fibers were obtained using enzymatic retting methods. The obtained fibers were treated with an alkali process to enhance their epoxy bonding capacities. Following this stage, the fibers were placed horizontally and added to the epoxy matrix with nanosilica powder. The nanosilica content was set at 3% by weight. Additionally, reference samples were produced from pure epoxy. The mechanical properties of the composites produced during the study were characterized by three-point bending tests in accordance with ASTM D790 standards. The results obtained showed that the composite material possesses high strength and elasticity properties. However, the non-uniform fracture behaviours may be due to variations in the material's production process. The study demonstrated the potential of natural composites in environmental sustainability and industrial applications.
