Abstract

Bu çalışmada bazalt ve cam dokuma kumaş ve fındık kabuklarının takviye malzemesi olarak kullanılmasıyla polimer matrisli kompozitler üretilmiştir. Matris olarak thermoset polyester reçine kullanılmıştır. Takviye malzemesinin içerisindeki fındık kabuklarının oranı ağırlıkça %5dir. Ayrıca 3 farklı boyutta fındık kabuğu kullanılmıştır. Üretilen kompozitlerin eğilme dayanımı ve ısı geçirgenlik özellikleri incelenmiştir

Abstract

Bu çalışmada ultrasonik yöntemle birleştirilmiş nonwoven kumaşların mekanik özellikleri incelenmiştir. Bu amaçla 3 farklı gramajda polipropilen, poliester ve poliester – viskon nonwoven kumaş kullanılmıştır. Ardından nonwoven kumaşlar birbirleriyle ultrasonik dikiş makinesiyle birleştirilmiş ve 2 katmanlı yapılar üretilmiştir. Ayrıca iki nonwoven kumaş arasına polietilen film yerleştirilerek bu 3 yüzey ultrasonik dikiş makinesiyle birleştirilmiş ve 3 katmanlı yapılar üretilmiştir. 2 ve 3 katlı yapıların kopma dayanımı ve kopma anındaki uzama özellikleri araştırılmıştır ve polietilen filmin 3 katmanlı yapıların mekanik özelliklerine etkisi incelenmiştir. En yüksek mekanik özellikler 3 katmanlı polipropilen – polietilen film – polipropilen yapısında elde edilmiştir, In this study mechanical properties of the ultrasonically bonded nonwoven fabrics were investigated. For this purpose polypropylene, polyester and polyester-viscose nonwoven fabrics which have three different fabric area densities were obtained. Then nonwoven fabrics were bonded to each other by using ultrasonic sewing machine and two layered structures were produced. Also polyethylene film was placed between two nonwoven fabrics and these three surfaces were bonded by using ultrasonic sewing machine and three layers fabrics were obtained. Tensile strength and elongation at break properties of the 2 and 3 layers structures were investigated and effect of the polyethylene film on the mechanical properties of the 3 layers structures was studied. And higher mechanical properties were obtained from the 3 layers polypropylene-polyethylene film-polypropylene structures

Author

Kayar, Mahmut, Mistik, S. İlker, and Simsek, Ramazan

Abstract

In this study ready-made garment waste cotton fiber were treated with NaOH and acetic acid then mixed with ready-made garment waste polyamide fiber and polymer composites were produced from these treated cotton/polyamide blend fibers by using thermoset polyester resin as matrix. Then flexural properties of the treated cotton/polyamide waste fiber blend thermoset polyester composites were investigated. [ABSTRACT FROM AUTHOR]
