Abstract

The use and utilization of composite materials is currently growing, along with the increasing use of these materials which are increasingly widespread, starting from simple household appliances to the industrial sector, both small-scale and large-scale industries. The purpose of this study was to determine composites made from polyester matrix reinforced with date palm fiber on the mechanical properties of impact strength and density tests. This composite study was carried out with the orientation of the arrangement of date palm fibers with a polyester matrix, the printing method used was hand lay up with three variables of immersion time KWP 1 KWP 2 and KWP 3, each variable there were 10 specimens. Furthermore, the density test to measure the mass weight of the specimen at each time of immersion. After conducting research, the results of the impact strength values of KWP 1 (5,209 Kj/m2), KWP 2 (4,896 kj/m2), and KWP 3 (4,393 kj/m2) were obtained. That the longer the process of immersing date palm fiber with NaOH solution, the easier it is for the fiber to break or be damaged, because the fiber will experience degradation or become brittle easily, Whereas the faster the 1.5 hour soaking time, the stronger the fiber texture, not easily broken. Keywords : Composite, Fiber, Matrix, Impact Test, and Density Test
