## 1 Introduction
NF such as banana, coir, date, wood, sun hep, hep, husk, jute, bamboo, roselle, sisal, pineapple, cotton, rice husk, abaca, kenaf, sugarcane (and bagasse), and flax fibers are increasingly used as reinforcing agents and filler for the reinforcement of PC with different fiber/particle geometries and properties, including the length, diameter, type, content, shape, thermal stability, structure (e.g., the proportion of crystalline fibrils and non-crystalline regions, spiral angle of fibrils), surface treatments, supramolecular structure, degree of crystallinity, degree of polymerization, crystal structure (e.g., type of cellulose, defects, the orientation of the chains of non-crystalline and crystalline cellulose), void structure (e.g., pore volume, specific interface, size of pores), whether the NF were taken from the original plant and the corresponding growing conditions [2; 15; 19; 25; 43; 44]. In this review study, the authors focused their investigation on the utilization of BF from the pseudostem without other particulate fillers as the reinforcement of PC. Table 1 shows some suppliers for commercial products made with BF. \begin{table}

Table 1: -Some suppliers for commercial products made with banana fibers. In general, all the mentioned companies in Table 1 do not buy the banana fibers firstly to a supplier. These companies are involved throughout all the processes, since the harvest of the banana bunches until the manufacturing of the commercial products and its sale (e.g., panels, paper, handicraft, furniture, etc.). In the next sections, more information about the properties and the surface chemical treatments (SCT) that have been done on BF, before their incorporation into polymeric matrices (PM), are presented and discussed.
