Pembuatan dan Karakterisasi Komposit Serat Palem Saray dengan Matriks Epoksi

Abstract

Has been done the research about synthesis and characterization of composite saray palm fiber with epoxy matrix with Chopped Strand Mat method. Composition saray palm fiber has made with variation 0%, 1%, 2%, 3%, 4%, 5% to total mass of matrix and which epoxy was used as matrix. Manufacture of composite SPS-E was, fibers soaked with NaOH for 1 hour, rinsed with clean water and dried, and then weighed. Epoxy mixed with its hardener by the motor stirrer then poured into molds and pressed 60 minutes at a temperature 70o C. The aim of this research is to obtain physical and mechanical properties. Value of density is 0,858 g/cm3 to 1,173 g/cm3 , value of water absorption is 0,75 % to 4,89 %, value of water content is 0,89% to 8,94 %, value of tensile strength is 9,61 MPa to13,14 MPa, value of flexural strength is 23,52 MPa to 104,85MPa and value of impact is 24,3 kJ/m2 to 38,5kJ/m2 . Composites are qualified Japanese Industrial Standard JIS A 5905: 2003. Composite of saray palm fiber with epoxy matrix can be used as material for car bumper.
