Ramie natural fibre-reinforced biodegradable composites: mechanical, absorption and thermal behaviour study

This study examines the mechanical, absorption, morphological, thermal, and characterization properties of short ramie fibres and epoxy polymer composites reinforced with different lengths of short ramie fibres and high-performance epoxy polymer composites. Ramie fibres of different lengths have not been extensively studied in polymer composites, despite the fact that they are commonly used. In this study, the purpose is to examine the use of ramie short fibre-reinforced composites in order to test their performance. There is an improvement in mechanical properties of composites made from ramie fibres. By using the epoxy polymer matrix and ramie short fibres (10, 15, 20, and 25 mm), composite samples were manufactured by compression moulding using epoxy polymer matrix. A number of mechanical properties of the composite materials were tested in this study, including tensile strength measured between 23.42 and 28.76 MPa, flexural strength measured between 36.82 and 46.82 MPa, and impact strength measured between 2.2 and 4.5 J. Temperature peaks were used to determine the decomposition temperatures for the ramie fibre-reinforced composite samples. In order to observe the bonding behaviour of these ramie fibre composites and the absorption of their primary and secondary phases, it is possible to use an electron microscope. As a result of the research reported in this paper, it has been found that using polymer matrix materials that contain ramie fibres of 20 mm can significantly enhance the performance of commercial particleboard applications.
