During the second half of the twentieth century, industrial and scientific interests in plant fibers (PFs) have resulted in their resounding comeback as engineering materials. This chapter is concerned with the characterization of PF materials. Good knowledge of the properties of these materials is essential for safe design of the related structures. Bast fibers that are collected from the phloem surrounding the stem of certain dicotyledonous plants, for instance, are among the most used, owing to their higher tensile strength. However, for an optimum utilization of PFs, a relevant assessment of their physico-chemical and mechanical properties is very crucial. As it is now well established, PFs’ properties are largely influenced by their hierarchic composite microstructure and their viscoelastic behavior. This book chapter focuses on the presentation of various experimental approaches used to characterize the elastic and viscoelastic behaviors of plant fibers. Consideration of their blending in sheet form and relevant mechanical properties will also be of interest.

Natural fibres are biodegradable materials that contribute to the development of a “green” economy due to their numerous merits such as energy efficiency, ease of manufacturing, environmental friendliness, low cost, sustainability, and biodegradability. Natural fibres have lately become more appealing to technology and innovation as substitute materials for synthetic fibre-based composites due to these qualities. Several projects have also been undertaken to reveal the potential applications, economic and environmental benefits of natural fibres sourced from plants for polymer reinforcements. Among the commonly used fibres are banana and sisal fibres which form part of the reasons for their selection in this review. The justification for this is the environmental concerns in the modern days which have increased the demand for natural materials as suitable alternatives for synthetic reinforcements. Hence, this review reveals the impact of banana and sisal fibres as reinforcements in polymers on the environment, the possible future processing pathways, and applications.

“…2 fibres/yarns in particular are selected as the reinforcing material due to the abundant availability, ease of manufacturing and most importantly, renewability. Banana is the most planted tree in Sri Lanka (469 842 tons/year, 49,168 hectare) and its fibres have been used in yarn manufacturing (Mumthas et al, 2019, Balakrishnan et al, 2019.…”

Green construction materials developed using renewable resources have become the focus of concurrent research owing to increasing environmental considerations and legislations. However, most of the available literature focus only on load-bearing construction elements. Consequently, little attention has been paid towards non-load-bearing construction elements such as partitioning materials. The present work aims to address this gap by investigating the viability of using the biodegradable bioplastic PLA in combination with yarns spun using banana fibres to manufacture a composite panel intended for temporary partitioning materials used in the construction industry. Pre-tensioned banana yarns were used as the reinforcement while PLA was used as the matrix. The composite panels were manufactured using the compression moulding technique. The effect of process parameters such as moulding temperature and pressure, the effects of the degree of pre-tension and the amount of reinforcing yarn on the performance of the panels were investigated. The optimum moulding conditions were found to be 180oC moulding temperature and 15 tonnes of moulding pressure. Yarn pre-tensioning exhibited a positive effect on the performance of the composite panels. However, increasing the reinforcing yarn percentage caused a degradation of flexural performance of the composite. Finally, the performance was compared against the most widely used partitioning material currently, medium-density fibreboard (MDF). The novel composite panel manufactured at optimum conditions exhibited 52% higher impact strength and 55% higher flexural strength when compared to MDF. The composite panel presented herein has the potential to replace MDF as a better performing material manufactured using renewable resources.
