- Abstract: Due to its eminent environmental concern, purely synthetic materials are being increasingly discouraged for application as dispersed phase in polymer matrix composites. Considering its mechanical properties, an ecological alternative for it is the use of Sisal fiber (Agave sisalana) as reinforcement. However, by reason of its hydrophilic nature, there is a necessity to improve the characteristics of the fiber in terms of decreased water absorption capacity, increased mechanical strength and improved thermal stability. The possible improvements currently studied are the surface modifications of plant fibers through physical and chemical treatments. This work has the objective of presenting two surface treatments of sisal fiber: acetylation and modification with hydrated aluminum oxide (Al2O3.nH2O), which is called hybrid. The fibers were characterized by Fourier transform infrared spectroscopy (FTIR). The presence of 0.72% (w/w) aluminum was observed by using dispersive energy spectrometry (EDS) attached to a scanning electron microscope. The manual rolling process was used to prepare the composites. Tests of water absorption in the composites showed a decrease in 33% when the acetylated fiber was used as reinforcement and 28% when using the hybrid.
