Aprovechamiento de desechos industriales de aceite de palma africana en el desarrollo de polímeros compostables, composites y sistemas de biofiltración.

Abstract

In recent decades, the idea of replacing synthetic fibers with natural fibers as reinforcing fillers in polymer matrix composites is quite promising, due to its low cost, biodegradability, and acceptable thermal properties. The objective of the curricular integration project is the thermogravimetric characterization of composite materials made with industrial waste from African palm (Elaeis guineensis Jacq.) stems and acrylic resin, which were subjected to accelerated weathering in salt spray. It was based on a statistical review regarding the mechanisms to determine the average length of the spine fiber, which was 778.6 um. Subsequently, and based on the information provided on the thermogravimetric behavior, the main stages of decomposition of the composites were determined at the different processing temperatures of 80°C, 120°C, 140°C, and 160°C and it was observed that does not significantly influence the percentage of weight loss, except at the temperature of 100°C where the degradation of the sample increased considerably The presented results of the percentages of weight loss obtained from the thermogravimetric analysis of the composite samples, for the tests without weathering were 3.09%, 29.5%, 49.9% and 3.7% respectively, and for the cases with accelerated weathering the percentages of weight loss in this case were 3.4%, 14.2% , 20.5%, 49.7% and 3.2% respectively. Finally, in conclusion, I could say that accelerated weathering is unfavorable because it accelerates the degradation of the composite material.
