In this study, the impact behavior of the two composites reinforced with jute fabric and wool felt is investigated. In order to increase the surface adhesion properties, the jute fabrics have been retained in 10% NaOH solution for 4 hours, then have been dried at room temperature. No treatment of the wool felt was undertaken. Composites are produced by vacuum infusion method with the same thickness. To measure the impact resistances, the composites are tested under three different energy levels. Impact behaviors of composites were evaluated by comparing load–deflection graphs and images of impacted specimens. Results Show that the damage of the composite reinforced with wool felt has seen to be less at the same energy level

JÜT KUMAŞ VE YÜN KEÇE ESASLI KOMPOZİTLERİN DARBE DAVRANIŞININ BELİRLENMESİ

Öz

Bu çalışmada jüt kumaş ve yün keçe takviyeli üretilen iki kompozitin darbe davranışları araştırılmıştır. Yüzey yapışma özelliklerinin arttırılması için jüt kumaşlar %10 NaOH çözeltisinde 4 saat bekletilmiş daha sonra oda sıcaklığında kurumaya bırakılmıştır. Yün keçe hiçbir işleme tabi tutulmamıştır. Kompozitler vakum infüzyon yöntemi ile aynı kalınlıkta üretilmiştir. Darbe dayanımlarının belirlenmesi amacı ile kompozit numuneler üç enerji seviyesinde test edilmiştir. Kompozitlerin darbe dayanımları hem kuvvet–çökme grafikleri hem de darbeli numune görüntüleri karşılaştırılarak değerlendirilmiştir. Sonuçlar, aynı darbe yükü altında yün keçe takviyeli kompozitte hasarın daha az olduğunu göstermiştir
