Analysing Flexural Strength of Induction Welded Epoxy Resin Coated Carbon Fiber/Basalt Fiber/PET Hybrid Composites

Öz

The increasing demand for lightweight, high-performance, and cost-effective solutions has accelerated research on hybrid composite materials. In this study, epoxy resin-coated carbon fiber fabrics, basalt fiber fabrics, and polyethylene terephthalate (PET) films were bonded using induction welding to produce hybrid composite laminates in a short processing period. The manufactured specimens were characterized through three-point bending test and scanning electron microscopy (SEM) analyses to evaluate their mechanical behavior and interfacial properties. The results revealed that the specimens exhibited flexural strength values of the literature average, while SEM observations confirmed effective fiber–matrix interaction. This study demonstrates that the utilization of low-cost, fast produced and widely available PET films and BF can contribute to the development of sustainable hybrid composites and support their broader adoption in the market.

İndüksiyonla Kaynaklanan Epoksi Reçine Kaplı Karbon Fiber/Bazalt Fiber/PET Hibrit Kompozitlerin Eğme Mukavemetinin Analizi

Öz

Hafif, yüksek performanslı ve uygun maliyetli çözümlere yönelik artan talep, hibrit kompozit malzemeler üzerine yapılan araştırmaları hızlandırmıştır. Bu çalışmada, epoksi reçine kaplı karbon fiber kumaşlar, bazalt fiber kumaşlar ve polietilen tereftalat (PET) filmler, kısa bir işlem süresi içinde hibrit kompozit laminatlar üretmek için indüksiyon kaynağı kullanılarak birleştirilmiştir. Üretilen numuneler, mekanik davranışlarını ve arayüz özelliklerini değerlendirmek için üç nokta eğme testi ve taramalı elektron mikroskobu (SEM) analizleri ile karakterize edilmiştir. Sonuçlar, numunelerin literatür ortalamasına yakın eğilme dayanımı değerleri sergilediğini, SEM gözlemlerinin ise etkili fiber-matris etkileşimini doğruladığını ortaya koymuştur. Bu çalışma, düşük maliyetli, hızlı üretilen ve yaygın olarak bulunan PET filmlerin ve bazalt fiber kumaşların kullanımının, sürdürülebilir hibrit kompozitlerin geliştirilmesine katkıda bulunabileceğini ve bunların pazarda daha geniş çapta benimsenmesini destekleyebileceğini göstermektedir.
