Resumen:
In recent years, thermoplastic materials are being
increasingly used for various applications. Because of their increasing use
combined with the high demand, the cost of the thermoplastic has increase
rapidly over the past decade. This situation made it necessary to use low cost
fillers as a means of reducing the cost of the end product. Natural
fiber-reinforced thermoplastic composites are more economic to produce than the
original thermoplastics (1). Cellulose-based natural fiber are
stong, light in weight, very cheap, abundant and renewable (2).
However, lack of good interfacial adhesion and poor resistance to moisture
absorption made the use of natural fiber reinforced composites less attractive.
This problem can be overcome by treating these fibers with suitable chemicals (1).
Cellulosic fibers are also reported to be generally
incompatible with polymers due to the hydrophilic nature of the former;
therefore, several treatments have been reported to improve the fiber-matix
interfacial bonding (3).
The effect of chemical treatment on the
tensile properties of sisal fiber-reinforced PCL/starch composites was
investigated.
