Komposit Hibrid Polyester Berpenguat Serbuk Batang dan Serat Sabut Kelapa
Abstract: Sawdust coconut
trunks of palm trees and fiber coconut coir are two waste materials from the
processing of coconuts and coconut tree trunks sawmill waste are plentiful
materials can be utilized for producing
composites using polyester
resins. Both each
properties materials as follow polyester resin: liquid in the open
air conditions, sawdust coconut and coconut coir fiber properties is
lightweight and fragile nature of the polyester adhesive used as a binder
(binder) between fiber coconut coir and sawdust coconut palm tree trunks as a
filler.
The variation volume fraction between the sawdust and coconut trunks of
fiber coconut coir in polyester
resin influence mechanical properties
for each composition of this
composite. By comparizing the
volume fraction of either polyester, sawdust coconut palm tree trunks and fiber
coconut coir (Coir coconut) using tensile test standard ASTM D638-I, and the
ASTM D6110 for impact testing. The
result of tensile
and impact test,
obtained that the
optimum percentage 30:10 per
cent, mean tensile strength on 95.953 N/mm2, mean elasticity
0,125 %, meanelasticity modulus
768.702 N/mm2, mean
absorbed energy 2,679 J
and mean impact
value0,068 J/mm2.
