Misvak, Borik Asit ve Porselen Atığı Takviyeli Polyester Matrisli Kompozitler

Öz

Yapılan çalışmada misvak, borik asit ve porselen atığı katkılı polyester matrisli hibrit kompozitlerin mekanik, fiziksel ve antibakteriyel özellikleri farklı uygulamalarda kullanılabilirlikleri hakkında bilgi edinmek için araştırılmıştır. Polimer matrisli kompozit ürünler döküm yöntemi ile üretilmiştir. Üretilen ürünlerin bulk yoğunluğu, gözenekliliği, üç nokta eğme mukavemeti, eğmede elastik modülü, shore sertliği, darbe direnci gibi fiziko-mekanik özellikleri belirlenmiştir. Taramalı elektron mikroskobu ile numunelerin parlatılmış ve kırık yüzeyleri incelenmiştir. Antibakteriyel testler ASTM 2180'e göre gerçekleştirilmiş, temas açısı ölçümleri yapılmış, yüzey enerjileri hesaplanarak antibakteriyel etki-temas açısı ilişkisi araştırılmıştır. Sonuç olarak, fiberimsi yapısı ve kimyasal içeriği nedeniyle misvak katkısının darbe direnci ve antibakteriyel etkiye olumlu etki sağladığı tespit edilmiştir.

Miswak, Boric Acid and Porcelain Waste Reinforced Polyester Matrix Composites

Öz

In the study, the mechanical, physical and antibacterial properties of polyester matrix hybrid composites with miswak, boric acid and porcelain waste additives were investigated to obtain information about their usability in different applications. Polymer matrix composite products are produced by casting method. Physico-mechanical properties such as bulk density, porosity, three-point bending strength, elastic modulus in bending, shore hardness, impact resistance of samples were determined. The polished and fractured surfaces of the samples were examined by scanning electron microscopy. Antibacterial tests were carried out according to ASTM 2180, contact angle measurements were made, surface energies were calculated and the antibacterial effect-contact angle relationship was investigated. As a result, due to its fiber-like structure and chemical content, the positive contribution of the miswak additive to the impact resistance and antibacterial effect was observed.
