Resumo
Natural cellulose-based fibers offer low cost, low density composite
reinforcement with good strength and stiffness. Because of their
annual renewability and biodegradability, natural fibers have
materialized as environmentally-friendly alternatives to synthetic fibers
in the last two decades. They are replacing synthetic materials in some
traditional composites in industrial manufacturing sectors such as
automotive, construction, furniture, and other consumer goods. In this
work, the use of lignocellulosic fibers in green materials engineering,
particularly their application as polymeric composite reinforcement
and surface treatment via ionizing radiation are reviewed. Because
these cellulose-based materials are intrinsically hydrophilic, they
require surface modification to improve their affinity for hydrophobic
polymeric matrices, which enhances the strength, durability, and
service lifetime of the resulting lignocellulosic fiber-polymer
composites. In spite of a long history of using chemical methods in the
modification of material surfaces, including the surface of
lignocellulosic fibers, recent research leans instead towards application
of ionizing radiation. Ionizing radiation methods are considered
superior to chemical methods, as they are viewed as clean, energy
saving, and environmentally friendly. Recent applications of controlled
ionizing radiation doses in the formulation of natural fiber –reinforced
polymeric composites resulted in products with enhanced fiberpolymer
interfacial bonding without affecting the inner structure of
lignocellulosic fibers. These applications are critically reviewed in this
contribution.
