Abstract

Natural fibers have many advantages and potentially attractive to be used as reinforcement material. Various types of natural fibers have been researched and developed to replace the use of synthetic fibers with improved mechanical properties able for various applications. It is more economical if the natural fibers are used as reinforcement material for polymer matrix composites (PMC). Chicken feather fiber (CFF) has good potential as reinforcement material. It is the objectives of this study to develop CFF reinforced polypropylene (PP) composites. The tensile properties were tested and compared to the original PP used as the control samples. CFF reinforced composite was prepared from raw chicken feather. The feathers were cleaned, soaked into organic solvent and dried until individual fiber is separated from each other. Later, the feathers are grinded to reduce the length so that the short fibers can be obtained, extruded and injection molded to produce test samples with different percentage of fiber volume fraction. There are 4 batches of samples which contain a range of volume fractions of CFF; 2.5 vol.%, 5.0 vol.%, 7.5 vol.% and 10 vol.%. After all the samples were prepared, tensile test was conducted. Stress-strain curve was produced from the test data and the results shown that the modulus of elasticity was improved to 12.9% at 5.0 vol.% of CFF and improvement in the stiffness of PP composite is observed at 2.5% vol. of CFF The fracture surfaces of the tensile specimens for all CFF/PP reinforced composites were examined by using scanning electrone microscope (SEM). Images obtained from SEM provided an insight on the interactions between the fiber-matrix composite. It is proven as the fiber content increases, the presence of voids and broken fibers were also observed which resulted in reduced properties.
