Abstract
Fiber pull-out modeling is engaged to bond mechanism of the interface between fiber and cementitious matrix. Hereby, the bond interface takes an important role in determining the whole composites structure performance. When a slippery fiber of nylon 600 is applied into fiber-reinforced cementitious composite (FRCC), then the bond interface mechanism should be increased to reach a better performance of whole composites. The clumped fiber end condition indicates some performance improvements, rather than the straight one. Advancement of the previous Susilorini’s model of fiber pull-out with clumped embedded fiber end will show that shear-friction stress takes major contribution in modeling of nylon 600 with clumped fiber end. The pull-out process involved stable fracture and unstable processed that are being specific interest in this research. The research delivers experimental and analytical methods. The experimental method conducts pull-out test with pull-out specimens categorized into specimens with straight fiber end and also specimens with clump fiber end. The fiber is nylon 600 made in Indonesia, diameter of 1.1 mm, and fiber embedded length lf of 100 mm. A computerized closed-loop universal testing machine is going to be precise equipment measuring the load and displacement of specimens during the pull-out test. The analytical method is modeling the fiber pull-out with clumped fiber end and resulting some formulas and theories for the process of fiber pull-out with clumped fiber end. The experimental results show that specimens with clumped fiber end reach loads about 1200-1400 N that are 14-35% higher that specimens with straight fiber end while the maximum displacement of those specimens reach around 100 mm. The analytical method successfully results the fiber pull-out with clumped fiber end model, and meet a finding of formulas and theories. The model of fiber pull-out with clumped fiber end model fit the experimental results.
