This chapter deals with the recent and emerging development of hybrid biocomposites. Hybrid composites have specific and idiosyncratic characteristics that can be used in a variety of structural components and structures without losing their structural efficiency and physical and mechanical properties; not only can hybrid biocomposites have improved structures, but they may also lead to major cost savings due to the inclusion of cheap raw materials of structural components and structures without losing their structural efficacy. Due to their advantages such as low cost, light weight, low density, biodegradability, environmentally safe and high specific mechanical properties, hybrid biocomposites have replaced conventional fibre composites for real practical applications over the last few years. In fields such as aerospace and automobile, there will be an improvement in the usage of natural fibre hybrid biocomposites, and there will also be demand for aerospace applications. Recently, many researchers are working on the research projects focusing on the creation of natural fibre composites and phenolic matrices to be used as commercial cabin interior panels. Efforts are ongoing to resolve concerns related to strength, adhesion between fibres and matrix, moisture and thermal resilience as well as compliance with airworthiness requirements. The latter section of the programme may deal with biopolymer matrices that will contribute to the production of advanced potential hybrid biocomposites for aerospace applications. With specific improvements, hybrid biofibres play an important role in multi-applications with unique improvement and increase the effectiveness of hybrid biocomposites. Hybrid biocomposites offer equal stiffness, resistance, strength-to-weight ratio and other physical and mechanical properties. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.
