Caracterización de materiales compuestos formulados con residuos de la industria aceitera y resina acrílica.

Abstract

The difficulties of wastes disposal in oil palm industry have promoted initiatives to convert thoses wastes into products with a higher added value, which is important in research and development of composite materials reinforced with lignocellulosic wastes. For this reason, the objective of this study is the characterization of composite materials based on oil palm (Elaeis guineensis Jacq.) empty fruit bunch and water-based thermoplastic acrylic resin by using Fourier transform infrared spectrophotometry. In doing so, data regarding to size fiber and infrarred spectra were previously supplied at five processing temperatures (80 °C, 100 °C, 120 °C, 140 °C and 160 °C) and subjected to weathering test in saline atmosphere for 330 hours. The spectrophotometric identification evidenced the presence of functional groups pertaining components of lignocellulosic fibers and acrylic resin matrix. Regarding the influence of temperature in processing, the characteristic bands of the functional groups that make up the composite material were observed to increase in intensity along with the increase in temperature. However, the characteristic bands of the functional groups showed greater changes in intensity and broadening with the decrease in processing temperature (80 °C, 100 °C and 120 °C) when subjected to salt weathering.
