Abstract
This study provides a short, succinct and convincing review of the studies
researchers have performed on sisal natural fibre and its applicability for selection and
use as a potentially viable and economically affordable reinforcement for engineering
composite materials. As the technologies are developing rapidly day by day and the
demand for developing and manufacturing eco-friendly materials is also increasing, the
use of the bio-degradable reinforcements, like bamboo, sisal, jute, cotton and hemp, is
of utmost concern. Made evident from a few to several other research studies, in
comparison to the fabricated natural fibre-reinforced composite materials, the sisal
fibres indicate considerable results that favour their applicability. Environmental
contamination happens in various aspects of industrial processes, such as production,
disposal, and recycling of synthetic fiber-reinforced composites due to their widespread
selection and use. Sisal fiber is a good example of an environmentally acceptable
natural fiber having significant mechanical qualities, which can be utilized for
reinforcing a variety of polymer matrices. This review article provides a coverage of
the intricacies specific to the manufacture of sisal fiber-reinforced composite materials,
variables that impact their characteristics, surface treatments used to prevent the
presence of flaws, and mechanical tests required to determine their strength. Prior
testing attempts on the sisal fiber-reinforced composites are addressed in order to aid in
future research to reveal the advantages and usage of such a material in a more
effective and efficient manner. The current era of rapidly changing manufacturing
environment and technological advancements highlighting such scenarios calls for a
substantial amount of research to be performed on: (i) structure of sisal fibre, (ii) sisal
fibre extraction/preparatory processes, and (iii) surface treatments of sisal fibres
combined with other matrices.
