PREPARATION OF NATURAL WASTE ADDED POLYMERIC COMPOSITE MATERIALS AND INVESTIGATION OF THEIR PHYSICAL PROPERTIES
Project no. 20643 · Status: Kapanmış · 2019
Summary
In this study, the physical properties of composites obtained using different ratios of unsaturated polyester and epoxy vinyl ester resins with natural waste seed were investigated. Composites were formed using waste coffee, cotton and olive beans in different proportions of 10%, 20%, 30%, 40% and 50% by mass. Styrene-based unsaturated polyester and epoxy vinyl ester resins were used as resins. Hand laying technique was used to form the samples. The plant waste fibers were first milled, passed through a 500 micron sieve, then combined with resin and poured into molds. After curing in an oven at a temperature of about 70 0C, various tests were performed to examine its properties. The obtained composites were subjected to density, hardness, low speed impact strength, thermal gravimetric analysis and SEM analyses were performed. It is an important advantage to find alternative raw materials to be used in industrial production, to reduce costs and to recycle waste. In addition, the recovery of waste goods is important for environmental awareness and social responsibility. Thus, more durable environmentally friendly structures will be formed at lower costs. In line with the data obtained, it is expected to provide new business lines and employment as well as ecological contribution. In this study, alternative raw materials to be used in industrial production have been revealed and within the framework of social responsibility, the raw materials that are waste are recovered and provided added value.
