The Utilization of Agave Cantula Roxb as Composite Strength on Fishing Boat Hull

Abstract

The objective of this study is to analyses the Agave Cantula Roxb tensile and bending strength. The analysis was further done to observe the sustainability utilization the Agave Cantula Roxb fiber as a composite strengthener for fishing boat hulls. The research was carried out at the metallurgy mechanical engineering laboratory, Engineering Faculty, Indonesia Paul Christian University, Makassar. The method used is making a specimen with a 0%, 20%, 30%, 40% and 50% fiber composition, while the catalyst composition as a hardener is about 10%. To determine the material mechanical strength, a tensile test was carried out where the specimen dimension was based on the ASTM D3039 international standard. While for the bending test, the specimen dimension was based on the ASTM D790-03. From the test result it is indicated that not all composite specimen composition can be used as ship hulls material. Based on the standard required by the Indonesian Classification Bureau, the composite tensile strength standard (σt) is about 10 kf/mm2 and a bending strength standard (σb) of 15 kgf/mm2. Based on standard required, the composite condition that fulfilled the requirements is the 50% fiber which has a tensile strength of σt = 11,8 kgf/mm2 and a bending stress σb = 25,41 kgf/mm2.
