ANALISA PERILAKU MEKANIK KOMPOSITSERAT KAPUK RANDU MENGGUNAKANMATRIK POLYESTER
Abstract: The background
research is the development of science and technology in the field of materials
engineering and the demands off indinga new breakthrough in the provision of
high quality materials and environmentally friendly. Composite materials of
natural fibers that are more light weight, malleable, corrosion resistance, low
price andeasy to obtain. This study uses materials such aspolyesterresin, and a
catalyst Randu Kapok fiber. Randomly arranged fibers incomposites with various
volume fractions of 15%, 25%, 35%. Making way press mold, bending tests were
conducted with a reference standard ASTM D790-02, tensile testing standard ASTM
D-638. Testing through the process of tensile and bending tests to determine
the mechanical properties of the composite. Greatest tension obtained in the
composite with 35% volume fractionis equal to 3,8046 MPa while the largest
bending strength of the composite obtained from volume fraction 15% at 84MPa.
Void formed causing the load can be held by thematrixis reduced due tolack of
homogenan specimens.
