Abstract

This research was conducted to help the monitoring process of Merapi Mountain, because the monitoring process mostly uses CCTV camera and satellite photo. This research provided monitoring process more effectively. This research was also to investigate the strength of the UAV flying wing fuselage structure within composite material, that used woven fiberglass 100 and epoxy hardener for Merapi Mountain monitoring mission. This research used a software to compare between simulation and the real tensile test. The software that used for the simulation is solidworks 2013. This research contained the real air condition in Merapi Mountain for the parameter against the flow simulation. The research generated 4 types of materials composite from the real structure of this UAV fuselage. There were 2 layers of fiberglass, 3 layers of fiberglass, 2 layers fiberglass with patch connection and 3 layers fiberglass with patch connection. The thickness of the 2 layers was 0,5 mm and for the 3 layers was 0,75 mm, and for the patch connection dimatere was 5 mm the patch connection used continuous fiberglass. The Composite composition used 80% of the matriks and 20% of the fibre, while for the ratio of the matriks used 3 : 1 according the rules of resin. Manufacture of the fuselage used hand lay up and vacuum bagging method. The results were the highest tensile strength was 3 layers types with 199 N/mm2 tensile strength and for the lowest was 3 layers with patch connection with 37,49 N/mm2 , and for the tensile strength by the simulation 3 layers was 3,49 N/mm2 and for the 3 layers with patch conncection was 4,2 N/mm2 . The result of the simulation showed that the average of the tensile strength of all types was lower than the real tensile test. That meant the material from this research was safe to use on Merapi Mountain.
