Resumen:
Biocomposites were produced using a biodegradable material as
matrix, and sisal fibers as reinforcement. The biodegradable material is a commercial
product called MaterBi-Y, which is based on a cellulose derivatives and starch
system. The characterization of these biocomposites was not done before and it is
necessary in order to select a material instead of nonbiodegradable matrices.
An alkaline treatment was performed in order to improve the mechanical
properties of the fiber. The effect of the treatment on fiber properties and on impact,
flexural, and tensile properties of composites were determined. Fiber content
enhances the tensile properties of the biodegradable matrix. Water sorption studies
were performed. The experimentally observed tensile properties (modulus and tensile
strength) of short sisal fiber-reinforced cellulose derivatives/starch composites with
different fiber loading are compared with the calculated values obtained from the
existing theories of reinforcement.
