There is a growing research interest in bio-based products due to the
rapid consumption of natural sources and synthetic production activities that are
responsible for environmental pollution. The Food and Agriculture Organization
(FAO) of United Nations, or the Common Fund for Commodities (CFC), for leaving
a clean environment for future generations and disposing of harmful chemicals has
foreseen the use of herbal-based materials; thus, legislation on the use of natural
materials and wastes has been adopted by governments in this context.
Nowadays, plant-based materials are generally used to produce light composites.
In this study, roselle (Hibiscus sabdariffa) fiber was employed to reduce carbon
footprint and increase sustainable production. For this purpose, Hibiscus sabdariffa
fibers which are shorter than 10 mm dissolved in 20% NaOH solution in which
microfibrils are obtained. Thereafter, microfibrils are mixed with polypropylene to
produce composite material. Polypropylene is the lightest polymer known to have a
density of 0.90 g/cm3
. The most important feature of polypropylene is its high friction resistance. This material is often mixed with herbal-based materials. The main
aim of this study is to increase the mechanical properties of the proposed material
as well as the cost-effective production. Mechanical (tensile, compression, hardness, notch impact) and non-flammable properties of composite structures were
measured. We observed that there is a strong correlation between the number of
waste materials and an increase in mechanical properties.
