STUDY ON TENSILE PROPERTIES OF SALAK FIBER (SALACCA-ZALACCA) REINFORCED CACO3/EPOXY RESIN HYBRID COMPOSITES
Abstract
In this study, the matrix modification of Salak Fiber (Salacca-Zalacca) (SF) reinforced
polymer composites with micro-particles is an effective way to improve its matrix properties.
After micro-particle modification, understanding mechanical properties is important in
structural applications, and improvement of such properties can lead to the usage in the wider
fields. The aim of this work is to investigate experimentally tensile properties of CaCO3
modified epoxy/SF micro-composites. For this, various amounts of CaCO3 microreinforcements
of 0, 2, 4, 6, and 8 vol% were added into the epoxy matrix, and the microreinforced
epoxy resin was used to impregnate SF by press moulding. The prepared fiber
reinforced micro-composites were subjected to tensile test. As a result of all experiments, the
addition of 4vol% CaCO3 micro-reinforced SF/epoxy resin hybrid composites yield the
optimum on tensile properties. The optimum of CaCO3-epoxy matrix was reinforced with
various SF content of 0, 10, 20, 30, and 40 vol%. The tensile strength of CaCO3-epoxy/SF
increases with increasing of SF content (from 0 vol% to 40% of SF). The strength of 134.49
Mpa was obtained at composite with 40 vol% of SF.
