Evaluation of Mechanical and Water Absorption Behaviours of Corn Shell/Pumice Reinforced Epoxy Composites

The research article focused on the effect of corn shell reinforced with epoxy composites. The randomly oriented corn shell reinforced/epoxy composites were prepared by hand lay-up technique with 5%, 10%, 15%, 20%, and 25% pomice powder weight. Tensile, flexural, and water absorption tests were used to determine the composite’s mechanical properties, The obtained results revealed that 20 wt% and 15 wt% pumice powdercould produce corn shell -reinforced composite with the highest tensile strength, flexural strength, and interfacial adhesion among all the prepared composites. The added of the pumice powder into the corn shell /epoxy composites enhanced their mechanical, and water absorption. The tensile and flexural strengths of the corn shell/pumice powde –epoxy composites (20wt% and 15wt%) were 11.745 and 11.250 MPa, respectively. In additon, The 25 wt.%, composite also displayed less water absorption behavior compared to the other composite.

Evaluation of Mechanical and Water Absorption Behaviours of Corn Shell/Pumice Reinforced Epoxy Composites

Bu çalışmada, Mısır kabuğu takviyeli-pomza tozu doldurulmuş epoksi resin matrisli kompozit malzemeler üretilmiştir. Bu malzemelerin Çekme, Eğme ve su emme direnci Ölçülmüştür. Bu amaç doğrultusunda matris elemanı olarak epoksi, takviye elemanı olarak mısır kabuğu kullanılarak elle yatırma yöntemi ile kompozit malzemeler üretilmiştir. Çalışma kapsamında ayrıca dolgu maddesi olarak 250 mesh altında ağırlıkça farklı yüzde oranlarda pomza tozu kullanılarak kompozit numuneleri de yapılmıştır. Üretilen kompozitlerde pomza tozu eklenmeden ve pomza tozunun eklenmesiyle çekme, eğme ve su emme özellikleri üzerindeki etkisi değerlendirilmiştir. Elde edilen sonuçlara göre, ağırlıkça %20 ve %15 pomza tozu katkılı kompozitin çekme ve eğilme sonuçları sırasıyla, 11.745 ve 11.250MPa olarak bulunmuş ve mekanik özelliklerini iyileştirdiği görülmüştür. Ayrıca, Ağırlıkça %25 Pomza tozu dolgulu kompozit diğer pomza tozu katkılı kompozitlere göre daha az su emme özelliği göstermiştir.
