Abstract

Son yıllarda, ürün-üretim döngülerinde sürdürülebilirlik yeşil mutabakat kapsamında üzerine en çok odaklanılan konulardan biridir. Kompozit malzemelerin kullanıldığı tüm sektörlerde çevre dostu malzemelerden üretilen ve geri dönüştürülebilir kompozitlere ilgi günden güne artmaktadır. Bu çalışma kapsamında, doğal elyaf takviyeli termoplastik kompozit malzemelerin akustik sektöründe kullanım potansiyeli incelenmiştir. Keten liflerinin tek doğrultuda yönlenmiş yerleşiminin sağlandığı keten/polipropilen tekyönlü prepreg yapılardan üretilen tabakalı kompozit malzemelerin ses yutum katsayısı ve ses iletim kaybı performansı ölçülmüştür. Alınan test sonuçları, keten/polipropilen tekyönlü prepreg yapılardan elde edilen tabakalı kompozit plakaların düz bir geometride kullanıldığı durumda kapalı gözenekli bir yapı sergilediğini ve bu nedenle darbe doğuşlu seslerin izolasyonunda kullanım potansiyeli olduğunu göstermektedir.

Environmentally Friendly Alternative for Noise Barriers: Natural Fiber Reinforced Composite Materials

Abstract

In recent years, sustainability in product-production cycles has been one of the most focused topics within the scope of the green deal. There is a growing interest in recyclable composites produced from environmentally friendly materials within all sectors where composite materials are used. In this study, the potential of natural fiber reinforced thermoplastic composite materials to be used in the acoustic sector was investigated. Sound absorption coefficient and sound transmission loss performance of laminated composite plates produced from flax/polypropylene unidirectional prepreg structures, in which flax fibers are arranged in one direction, were examined. The test results show that the laminated composite plates produced from flax/polypropylene unidirectional prepreg structures exhibit a closed-pore structure when used in a flat geometry and therefore have the potential to be used in the isolation of structure-born sound.
