PERILAKU LENTUR PANEL SANDWICH YANG DIBUAT DARI KOMPOSIT SERAT ABAKA SEBAGAI SKIN DAN KAYU SENGON SEBAGAI CORE

Green building material is a concept that makes up a lot of construction materials developed in modern times. Construction material with green building concept has criteria such as lightweight raw material, high mechanical strength, abundant availability and renewable material. Sandwich is a lightweight composite material, has good strength. Combination of natural materials to be applied as a sandwich material can increase the economic value and environmentally friendly aspects. This study aims to determine the effect the configuration of natural fiber on the skin of the sandwich capacity to support the bending load.Making sandwich using the hand-lay up method. Skin of the sandwich is made from a composite fiber musa textile polyester which varies in the direction of the fiber, namely elongated, random dan woven fibers. Sengon wood is used to as a core component of the sandwich. Type of adhesive used to glue the skin to the core is epoxy glue. Time dimensions of specimen are 550 mm x 60 mm x 24.4 mm, with a skin thickness of 3.2 mm and span of 450 mm. Testing the flexureal strength of the sandwich using the four point bending loading method.Sandwich flexural strength is directly proportional to the mechanical strength of Abaka-polyester fiber composites where the highest flexural strength is shown by the sandwich with an longitudinal fiber configuraton of 81,96 Mpa, followed by random fibers of 62,64 Mpa and woven fiber of 47,87 MPa. Highest flexural strength sandwiches is higher than class II wood, namely Meranti wood with a percentage difference of 68,64 %. The highest deflection value of the sandwich with longitudinal fiber configuration is 25.82 mm. Inthe sandwich specimen there are two patterns of collapse namely the pattern of collapse of the skin thensile and shear core. Skin tensile collapse occurs in random and woven fiber sandwich specimens while core shear collapse occurs in longitudinal fiber sandwiches
