Extraction and characterization of lignocellulosic fibers from Luffa cylindrica fruit

ABSTRACT

The need for recyclable, renewable materials has resulted in an increased use of natural fibers for reinforcing polymers to suit a wide variety of applications. This study is mainly focused on the extraction and characterization of the lignocellulosic fibers derived from the ripened, dried Luffa cylindrica L. fruit. Characterization studies such as Fourier transform infrared spectroscopy, X-ray diffraction, and thermogravimetric analysis are conducted and reported. Composite samples prepared using unsaturated polyester resin show an increasing impact strength on fiber loading. Fractured surface of the composites are examined using scanning electron microscope. Results show the feasibility of fibers for reinforcement in polymers.
