| dc.description.abstract | In this paper, the effect of addition the natural fiber as filler in
thermoplastic polyurethane (TPU) has been determined. The pineapple leaf fiber
reinforced with thermoplastic polyurethane has been developed by varying
parameter which is fiber loading percentage (5, 10, 15, 20 and 25%). After sample
preparation, the composite of the pineapple leaf fiber and thermoplastic
polyurethane(TPU) was undergo few test such as tensile test , scanning electron
microscope (SEM), thermogravimetric analysis (TGA), and swelling test to
determine the characterization of pineapple leaf fiber filled TPU composite. The 5%
filler loading of TPU/PALF composite showed the highest value of tensile
strength and elongation at break, this may due to good interfacial adhesion of the
filler-matrix and good distribution of filler within the matrix and this can proved
by the micrograph of SEM. In addition, the swelling index of the TPU/PALF
composite increase as the filler loading increase, because the fiber contain a lot of
the porous structure and poor interaction of PALF particular in the matrix, so
cannot prevent direct diffusion of oil molecules into the composite. In the TGA
testing shown the poor thermal stability as the filler loading increase is due to
increase content of low thermal stability of PALF and the poor fiber-matrix
interfacial interaction on the composite. | en_US |
