Abstract
Application for usage of sandwich composite structures has been widely used in many engineering fields such as civil construction, marine structure, and offshore use as their characteristics suit for this usage. In this study, comparing the results of three-point bending tests through experimental and finite element analyses of sandwich composite structures has been investigated. This research is conducted with fiberglass and a core material which is carbon from mangrove carbon powder with different cores thickness (8 mm, 9 mm, 10 mm) and two types of sandwich layers (double and triple layers). It was found that, based on the data gained from the simulation, both with highest carbon content (10 mm) recorded the highest stress and strain. For the double layer with 10 mm carbon powder content, the maximum stress is 64.04 MPa while for the triple layer it is 66.22 MPa. When the percentage of the mangrove carbon powder increased or the core’s diameter increased, all the values of maximum stress, maximum strain and maximum displacement also have been increased. This data can be simply used for better understanding, the more layer and higher carbon content of the core, the highest maximum point of stress and strain can withstand before the specimen yield of fails.
