Annual Plant Reinforced Biocomposite Fiberboards—Investigation on Mechanical Properties

In this century, notable advancements have been observed in green technology in the field of materials science through the creation of biocomposites in response to the effects of global warming and environmental sustainability. Natural fiber-reinforced biopolymers are termed biocomposites. Due to their exceptional physicochemical and mechanical properties, natural fibers already have a leading share in the composite area. In addition, natural fiber has numerous advantages over synthetic fiber, including biodegradability, biocompatibility, light-weight, low cost, higher life-cycle performance, eco-friendliness, renewability, and improved mechanical properties. As a result, researchers have been working on these materials as a replacement for non-renewable, obstinate, or toxic materials. Moreover, biocomposites made from natural resources greatly enhance viability in the design of materials for future generations, and over the past decade, they have achieved significant expansion in the residential sector, architectural features, aviation industry, circuit boards, and automobile industries. Thus, making fiberboards from biocomposites reinforced with natural fibers from annual plants will be incredibly effective in terms of the fiberboard’s mechanical and thermal properties. This chapter focuses on the mechanical properties of fiberboards manufactured from biocomposites which are reinforced with annual plant fibers. Bast fibers, leaf fibers, seed fibers, core fibers, grass and reed fibers, as well as other varieties such as wood and roots, are all-natural fibers extracted from annual plants.
