The effects of benzyl urea into RHDPE/NR/CFF composites with different fibers loading were studied. The composites were prepared using BrabenderPlasticorder at 160 °C with rotor speed of 50rpm. The composites were characterized in respect of their tensile properties and morphology. The results indicated that RHDPE/NR/CFF with benzyl urea composites show higher values of tensile strength, Youngs modulus, but lower elongation at break than RHDPE/NR/CFF composites. RHDPE/NR/CFF with benzyl urea composites gave a better interfacial adhesion between the matrix and the fiber than RHDPE/NR/CFF composites as evidence using SEM.

As a consequence of modern life and technology, noise causes many negative side effects, especially with regard to health. Today, the presence of acoustic problems in transport vehicles such as airplanes, cars and train wagons has become one of the major problems of modern life. Many methods and materials have been developed to provide acoustic comfort in indoor spaces. One of them is the development and application of sound-absorbing materials. Nonwoven webs, which are considered to be the most ideal materials for sound insulation, have micron-sized pores as well as large surface areas. Among these materials, materials with double-layered porosity have greater effect. In recent years, researchers are increasingly turning to the development of sound-absorbing materials from production waste and natural materials that are easily decomposed in the environment. In this study, the sound-absorbing properties of nonwoven webs produced from chicken feather fibers, a by-product in chicken production and a significant amount of waste, were investigated. For this purpose, nonwoven web samples with different parameters were produced by using different binding materials by using thermal bonding method. The sound absorption coefficient and sound transmission loss values of the samples were measured and evaluated. As a result of the analyses, the influence parameters such as thickness, bulk density and porosity on the sound insulation properties of the produced samples was revealed. The assumptions concerning the mechanism of sound insulation of nonwoven webs produced from chicken feather fibers are detailed. Studies have shown that nonwoven webs from chicken feather fibers can be used as soundproof materials because of their good sound-absorbing properties.

In this paper, chicken feather fibers (CFFs) from poultry industries were used as reinforced materials incorporated with unsaturated polyester (UP) to create composites. It is prepared by varied the percentage weight fraction of CFFs by 2wt%, 4wt%, 6wt%, 8wt%, and 10wt%. Alkaline treated potassium hydroxide (KOH) was used to alter the structure of the CFFs. From the results it showed that the tensile strength of the CFFs/UP composites was reduced. The flexural modulus has optimum results of 35.3MPa, improved by 11.86% from pure UP (31.1MPa). For flexural modulus at 2wt% and 4wt% the untreated CFFs/UP performed better performance. However, started at 6wt% onwards, chemically treated fibers surpass untreated fiber. Even though CFFs has unique characteristics properties such as hollow honeycomb structure and low density, the poor adhesion due to its smooth surface roughness and uneven distribution of fiber during mixing contributed to the low strength and flexural values. Thus, treatment caused changes in the structure of the CFFs to increase the surface roughness of the fibers, which improve adhesion.
