Abstract
Biocomposites containing natural fibers and biopolymers are an ideal choice
for developing substantially biodegradable materials for different applications.
Polylactic acid is a biopolymer produced from renewable resources and has
drawn numerous interest in packaging, electrical, and automotive application
in recent years. However, its potential application in both electrical and automotive
industries is limited by its flame retardancy and thermal properties.
One way to offset this challenge has been to incorporate natural or synthetic
flame retardants in polylactic acid (PLA). The aim of this article is to review
the trends in research and development of composites based on agricultural
fibers and PLA biopolymers over the past decade. This article highlights recent
advances in the fields of flame retardancy and thermal stability of agricultural
fiber-reinforced PLA. Typical fiber-reinforced PLA processing techniques are
mentioned. Over 75% of the studies reported that incorporation of agricultural
fibers resulted in enhanced flame retardancy and thermal stability of fiberreinforced
PLA. These properties are further enhanced with surface modifications
on the agricultural fibers prior to use as reinforcement in fiber-reinforced
PLA. From this review it is clear that flame retardancy and thermal stability
depends on the type and pretreatment method of the agricultural fibers used
in developing fiber-reinforced PLA. Further research and development is
encouraged on the enhancement of the flame retardancy properties of agricultural
fiber-reinforced PLA, especially using agricultural fibers themselves as
flame retardants as opposed to synthetic flame retardants that are
typically used.
