Investigation Of Mechanical Behavior Of Hybrid Composites Reinforced Nettle Fiber-Hazelnut Shell Flour.
Journal Title: Gazi Üniversitesi Fen Bilimleri Dergisi Part C: Tasarım ve Teknoloji - Year 2017, Vol 5, Issue 4
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. Mechanical behavior in the study was investigated in the context of fracture, three point bending and impact test. 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.
