Chemically Treated

The effects of chemically treated natural fibres (rice straw and kenaf) embedded as filler into polypropylene matrix were investigated for its sound absorption properties to regulate the industrial noise. In this respect, untreated natural fiber as well as treated natural fiber reinforced with polypropylene composites were fabricated and compared. The composites were prepared by compression moulding technique. Its sound absorbing characteristic was investigated with the Impedance tube, according to a transfer function method. A two microphone setup was fabricated according to American society for testing materials ASTM E1050-10 and it is used to measure sound absorption coefficients of composites in the frequency range of 300 Hz to 2000 Hz. The sound absorption coefficients of the composites increased with the frequency. However, at 1000 Hz, the sound absorption coefficient decreased for all treated samples and then increased again which is due to specific character of natural fibers. This point of inflexion was due to the specific characteristic of natural fiber reflecting sound at around 1000 Hz, but absorbing sound in the middle and high frequencies. The results indicates that the process of chemical treatment enhanced the sound absorption coefficients by 12.5% for rice straw reinforced Polypropylene and 15.78% for kenaf fiber reinforced Polypropylene composites respectively.

Properties Of Composites

Rice straw/Poly(butylene succinate)(PBS) composites were prepared by injection molding machine. The influence of content and particle size of rice straw on the mechanical properties of composites indicated that with the increase of rice straw content the tensile strength and fracture strain of the composites was decreased. With the same content of rice straw, the smaller particle size, the more obvious decreased. The influence of dosage of silane coupling agent(SCA) on the composites was studied, the result indicated that with the increase of SCA content, the interface of composite materials significantly improved, the Young’s modulus increased 362% after rice straw was treated by SCA. Thermal analysis showed that the adding of coupling agent didn’t undermine the thermodynamic stability of the composites.
