Abstract

This paper discusses about an experimental investigation of tensile strength and impact properties of polymeric foams-OPEFB fiber sandwich panels composite with various directions of palm empty fruit bunches fiber, vacuum pressure, and foam thickness. In this study, the manufacture of specimens with different fiber directions will then be tested and analyzed for each direction of fiber. The results of the analysis of composite specimens in the study were evaluated and compared with each other. The purpose of this study was to obtain impact energy and tensile strength of composite plates. In the manufacture of sandwich panel specimens carried out by varying the pump pressure, foam thickness, and the direction of the preparation of the fiber and carried out by the vacuum method. From the test results, it was found that the highest tensile strength was composite specimens with vertical fiber direction is specimens with three vertical panels of fiber direction, vacuum pressure 6 cm Hg, and foam thickness is 1.5 mm with tensile strength is 22.5 N/mm2, while the highest impact energy is the specimen with vertical fiber direction is the specimen with the fiber direction of the three vertical panels, the vacuum pressure is 6 cm Hg, and foam thickness of 1.5 mm with an impact price of 0.16 J/mm2. From this study it can be concluded that the fiber direction is 53% higher than the direction of the combined fibers vertically, horizontally, and vertically in absorbing impact loads, also 83% higher than the vertical, 45°, and horizontal combined fibers in absorbing impact loads It also has a tensile strength of 10% higher than the vertical, horizontal and vertical combined fiber direction, also has a tensile strength of 15% higher than the vertical, 45° and horizontal combined fiber direction.

Abstract

The fracture surface of oil palm empty fruit bunch (OPEFB) reinforced polymer composites sandwich panels depends on different fibers treatment was experimentally investigated under static loading conditions. The static uniaxial tensile and flexural loading for three treatment modes on OPEFB fibers was implemented using servo hydraulic material testing machine. The microstructure was observed using SEM observation in order to better understand damage mechanism during the stress of polyester phase. SEM observation on fracture surface can provide important information for research and development as well as fracture analysis. It was found that fracture modes were considerably different for these composites. OPEFB fibers was soaked with 5% NaOH solution for 2 hours are not removed from the matrix composite. It means the interface bonds of OPEFB fibers can be controlled against the polymer matrix. Damage to polymer matrix interface and OPEFB fiber are boiled with water at temperatures of 50º C to 80º C for 30 minutes due to flexural test.
