Tekstil Takviyeli Beton Üretiminde Kullanılmak Üzere Yüksek Performanslı Hibrit İplik Geliştirilmesi Ve Üretim Parametrelerinin Optimizasyonu

Abstract

Textile-Reinforced Concrete (TRC) is a new construction material and has been used in civil engineering applications such as façade systems, sandwich panel and outside furniture during the past several decades. Generally in TRC, glass, carbon filaments, etc. are used to reinforce concrete because these high-performance filaments have superior mechanical properties and corrosion resistance. Coating of these filaments with different polymers provide extra performance for TRC’s durability. But, because of coating materials’ cost and stiffness, using of coating for TRC is not so advantageous. For these reasons, new approaches are needed. In this study, a new hybrid yarn design and production for TRC are emphasized. AR-Glass and polypropylene filament were used for production of hybrid yarn by commingling method. It was aimed to optimize the parameters of commingling yarn production with Taguchi orthogonal design. The experiments were performed by using L9 orthogonal matrix with respect to Taguchi approach. The best strength value in the study was obtained in production parameters where the machine production speed is 50 m / min, the air pressure is 6 bar and the feeding amount is 2%. Analysis of variance (ANOVA) and signal/noise ratio were used to evaluate the experiment results. As a result of the analysis, it has been observed that the machine production speed has the greatest effect on the breaking strength and the feed amount has the lowest effect.
