Abstract

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...
