KAJI EKSPERIMENTAL MATERIAL KOMPOSIT UNTUK DINDING PERAHU BERPENGUAT BAMBU DI LAPISI FIBER DAN RESIN SEBAGAI MATERIAL ALTERNATIP POSISI SERAT VERTIKAL

Abstract

With the times will be difficult to obtain good wood material in the market or in the forest, because the forest has been protected by the government and must be on guard sustainability, which businesses boat from ancient times until now dependent on wood as the main raw material in the manufacture of boats, so therefore we need to think of a raw material for boat walls are made of more modern material that is of composite, because the composite material means a combination of two or more different materials are combined or mixed macroscopic be a useful material. Composites in this study use of natural reinforcing fibers are Bambu Apus, as for the reason of using bamboo is a material that is sturdy, strong and lightweight and abundant materials commonly found tropical areas, especially in Indonesia and also bamboo has a tensile and bending properties are good, and coated glass fiber material Chooped Strand Mat, and Woven Roving, as the fiber coating in order matrix used is not brittle and fragile and improve the mechanical properties of bamboo of fragility, bermatriks Polyester Resin Yukalac type UPR-EX Series 157® BQTN mixed hardener, by doing study to examine the mechanical properties of the composite, ie Sceleroscope method Shore hardness testing, and Charpy Impact test. With the vertical position of the fiber, which is a composite test specimens layers I, II, and III, as a comparison, of each type of coating used bamboo size 5: 5 mm and 1: 5 mm, coated glass fiber material. After testing, the analysis of data obtained discussion of the results of the testing of composite types menedekati ideal and minimal value is influenced by factors that can reduce the mechanical properties of the composite that is contained in the composite layer II uses bamboo size 1: 5 mm with a hardness value of 66.6 shore, and the price impact is obtained 44.60 Nm, which is either used for the wall material alternatives boat as a substitute for wood.
