“…Also, the matrix appears with striations and deformations around the fiber; this is evidence of the strength transmitted between fiber and matrix. In addition some fibers' extremities are cracked very close to the matrix, showing good adherence [22,27]. Only a few voids are located in the surface caused by slips of fibers, but in general good dispersion and evident fiber-polymer interactions were noticed.…”

“…During the last decade, an increasing amount of research has been published involving keratin fibers from chicken feather with synthetic polymers, such as grafting with polymethylmethacrylate [19,20] and polyhydroxyethylmethacrylate [21]; composites with polyethylene [22,23], polypropylene [24][25][26], polymethylmethacrylate [27], polyurethane [28] and phenol-formaldehyde [29], among others [18], however there are only few related to keratin fibers and biopolymers [30,31].…”

Abstract:The performance as reinforcement of a fibrillar protein such as feather keratin fiber over a biopolymeric matrix composed of polysaccharides was evaluated in this paper. Three different kinds of keratin reinforcement were used: short and long biofibers and rachis particles. These were added separately at 5, 10, 15 and 20 wt% to the chitosan-starch matrix and the composites were processed by a casting/solvent evaporation method. The morphological characteristics, mechanical and thermal properties of the matrix and composites were studied by scanning electron microscopy, thermogravimetric analysis, differential scanning calorimetry and dynamic mechanical analysis. The thermal results indicated that the addition of keratin enhanced the thermal stability of the composites compared to pure matrix. This was corroborated with dynamic mechanical analysis as the results revealed that the storage modulus of the composites increased with respect to the pure matrix. The morphology, evaluated by scanning electron microscopy, indicated a uniform dispersion of keratin in the chitosan-starch matrix as a result of good compatibility between these biopolymers, also corroborated by FTIR. These results demonstrate that chicken feathers can be useful to obtain novel keratin reinforcements and develop new green composites providing better properties, than the original biopolymer matrix.

“…It is commonly know that synthetic polymers are mostly highly combustible while some biopolymers exhibit antyoxidative properties such as amino acids derived from keratin [12,13]. Keratin itself also shows antyoxidative properties, containing an amount of about 15 % of nitrogen in its structure.…”

The need for new composite materials that would exhibit good parameters such as mechanical or thermal properties, while being easily processable and able to undergo biodecomposition after its period of use, has been a great source of inspiration for modern material science. A lot of work has been done in the field of biodegradable polymeric materials throughout almost every aspects of life, from medical materials, through disposable plastic bags to materials used in agriculture. In the latter field, several synthetic and natural polymeric materials are used. The present work will show one such composite, which is an innovative cellulosic-elastomeric material containing a modified protein, thus consisting of components of natural (cotton, protein) and synthetic (carboxylated styrene-butadiene latex) origin. The material could be applied in agriculture for mulching and as such will be directly subjected to the effect of temperature. Therefore, a better understanding of its thermal properties could shed some light on its applicability in real-field conditions. Therefore, TG and DSC analyses were performed, showing that different mechanisms of decomposition occur in the latex film than the coated cotton fabric. The modified keratin also slightly increases the temperature of glass transition. Additionally, the presence of modified keratin increases the susceptibility of the coated fabric to undergo biodecomposition.

“…Also increasing the fibre content have resulted an increase on the impact strength and on the shear modulus. Later, Barone et al [4] used chicken feathers for their polyethylene-based composites. In their work; they studied compounding time, temperature, speed, fibre dispersion and established that keratin feather fibres presented increase on stiffness in HDPE but provided lower tensile breaking stress.…”

Today, felt and woven fabrics are used as a reinforcement material in textile composite structures. In these structures glass and carbon fibres are the widely used ones. However for almost a decade, researchers have also shown some interest on natural fibre reinforced composites. In this study, it has been aimed to use wool waste fabric to be able to produce a lightweight composite material. For this purpose, the composite samples were produced by using wool fabrics in warp direction together with their waste blends as a reinforced material. The produced reinforced wool composite structures were then tested for both their mechanical properties, i.e. Izod impact and tensile strength tests, and for their thermal properties. The fracture surfaces of the samples were also inspected on the scanning electron microscope. According to the results, it has been evaluated that wool fabrics and their waste may be used as a reinforcement material for the application of textile composites presenting in lightweight structures for the construction industry. The wool waste fabric reinforced composites' mechanical properties can be improved by studying various waste percentages in future studies to gain better mechanical properties. The thermal conductivity of the composites was increased as the waste increases within the structure. As a result, wool waste materials can as well be used for future recycled textile materials in lightweight reinforced composites.
