Abstract

Polymer beam specimens produced with reinforcement of nettle fiber and fixed nut hazelnut flour at different volume ratios were opened initial notches with a / W = 0.2, 0.3 ratios after thermal curing. The volume percentage of nettle fiber in the composite is 2.5, 5, 7.5 and 10 percent. The grain size of hazelnut shell flour is 0-50μ and the volume ratio in the composite is 15% in all samples. Mode I fracture behaviors of compacted specimens from single sides, compact tensile and mechanical behavior were determined by three point bending test and impact test. The amount of crack opening was determined by the high-speed camera recorder. The bending test determined bending modulus and bending stresses. The morphological structure of the fractured surfaces obtained from the impulse test was revealed by sem views. It has been observed that the added hazelnut flour enhances the flexural modulus while reducing bending stress, fracture strength and impact resistance

Özet

Farklı hacim oranlarında ısırgan lifi ve sabit oranda fındıkkabuğu ununun takviyesi ile üretilen polimer kiriş numunelere, ısıl kür işleminden sonra, a/W= 0,2, 0,3 oranlarına sahip başlangıç çentikleri açıldı. Isırgan lifinin kompozit içerisindeki hacım oranları yüzde olarak 2,5, 5, 7,5 ve 10 dur. Fındıkkabuğu ununun tane büyüklüğü 0-50µ ve kompozit içerisindeki hacim oranıda tüm numunelerde yüzde 15’dir. Tek kenardan çentik açılmış kompozit numunelerin mode I kırılma davranışları kompakt çekme ve mekanik davranışlar üç nokta eğme testi, darbe testi uygulanarak ortaya konuldu. Çatlak açılma miktarı yüksek hızlı kamera kaydedicisi ile tesbit edildi. Eğilme testi ile eğilme modülü ve eğilme gerilmeleri belirlendi. Darbe testinden elde edilen kırık yüzeylerin sem görüntüleri ile morfolojik yapı ortaya konuldu. İlave edilen fındıkkabuğu ununun eğilme gerilmesi, kırılma dayanımı ve darbe direncini azaltırken, eğilme modülünü artırdığı gözlemlenmiştir.
