Effect of OPEFB treatment on the mechanical behavior of polymeric foams-OPEFB fiber sandwich panels composite
This work investigated the effects of oil palm empty fruit bunch (OPEFB) fiber treatment on mechanical behavior of polymeric composite-OPEFB fiber sandwich composite panels. 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 the fiber treatment method. In this work, tensile strength and impact of composite with OPEFB fiber boiled in water 50oC higher than other fiber treatments. (2) The time and speed of fiber chopping influence the tensile strength and impact of polymeric composite-OPEFB fiber sandwich composite panels. tensile strength and impact decreases with increasing time and speed of cutting tools on OPEFB fiber chopping.
