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, ...

The treatment method used is boiling and chopped OPEFB fiber. The treatment with boiling and soaking fiber varied: boiling in water temperature 50oC for 30 minutes, soaking in room temperature with NaOH for 2 hours, boiling with NaOH solution at a temperature of 50oC for 30 minutes. The time of chopping the fiber is varied from 1 to 3 minutes at two speed of cutting tools which are 1280 and 2560 rpm. OPEFB fiber orientation in this study is a random discontinuous direction. Laminates on polymeric foam composites consist of 3 sandwich layers. Polymeric composite-OPEFB fiber sandwich composite manufacturing with vacuum assisted resin infusion (VARI) method. The obtained summaries are as follows: (1) The tensile strength and impact value of polymeric composite-OPEFB fiber sandwich composite panels are influenced by...
