Resumo(s)
Composite materials were prepared by com pounding and hot-pressing PP or MAPP and lignocellulosic
fibers extracted from the rachis of Musa acuminate Colla var.
Dwarf Cavendish banana tree. The fibers were used as raw
filler or after a chemical treatment expected to remove most
of the extractible compounds. The resulting materials were
characterized using SEM, DSC, DMA, tensile tests and water
sorption experiments. All results show that the main aspect
involved in the interfacial adhesion between the polar filler
and the non-polar matrix is the extraction of lignin and fatty
substances. This results in higher values of the degree of
crystallinity and crystallization temperature of the matrix,
higher mechanical properties and lower water sensitivity.
