Investigation of the properties of paper dough and sisal fiber reinforced pla bio composites, kraft paper

Biocomposites are composites of natural fibers with non-biodegradable polymers such as petroleum-derived PP (poly propylene), PE (Poly ethylene), epoxides, or biopolymers such as PLA (Polylactic acid) and PHAs. Disadvantages of carbon, glass fiber and aramid fibers, excessive energy consumption, high environmental impact, cost and waste disposal at the end of life have led to the use of natural fibers (NFC) reinforced polymers in a wide range of industrial applications. The use of natural fibers to reinforce petroleum derivatives polymers is becoming more common, especially in the automotive and construction sectors. Green composites are a particular class of biocomposites in which a biologically based polymer matrix is reinforced with natural fibers and represents an area emerging in polymer science. Today, public concern about the environment and the limited availability of fossil fuels have forced governments, companies and scientists to find alternatives to crude oil and develop sustainable materials from renewable sources. Thus, the most recent innovation in the field of biocomposites is the replacement of petroleum-derived polymers with their polymers as matrix components from renewable sources (bio-based polymers). In this study, mechanical properties of natural fiber reinforced PLA green composites were investigated and compared with the pure form of PLA. In the selection of natural fibers, sisal and kraft paper, which are valuable plants, were selected. The submitted thesis was carried out as a 2017 BAP project and finalized. In this project, literature research and sample creation programs were prepared, samples were prepared, tests were performed, results were analyzed, reports and presentations were presented to conferences and seminars. The prepared paper was presented as a poster in the Project Market from Karadeniz Technical University 2019 Think to Reality in collaboration with Bursa Technical University and Berteks Textile. PLA green composites were obtained by pressing 0%, 10%, 20%, 30%, sisal fibers on the interface by pressing 260 gr PLA chips at 190 ° C in 100 g / m² paper reinforcement. The mechanical properties of the plates obtained from paper reinforced PLA green composite materials containing 0%, 10%, 20%, 30% sisal were compared with the mechanical properties of the PLA raw material plate. When comparing mechanical properties, tensile strength and bending strength values were taken into consideration. Green composites is a new field that is especially studied in our country. The necessity of producing products with high added value for the development of our country's economy has accelerated the work especially in the field of composite materials. The realized BAP project and master thesis will contribute to the literature, especially in our country, and material analysis made with the thesis will be able to diversify the usage areas and sectors of environmentally friendly polymer PLA and natural fiber sisal.
