• Abstract:

  This review article investigates the production chain of piassava fiber, a natural fiber from different locations in Brazil, the two main ones being the Attalea funifera palm, found in the Atlantic rainforest of Bahia, and the Leolpodinia Piassaba, found in the Amazon rainforest in the Barcelos region. The article brings together analyses of the properties that make Piassava a valuable material for use in composites. Initially, the fundamental concepts related to the fiber are discussed, followed by a detailed analysis of the extraction and treatment process, which includes the cleaning and selection stages, carried out predominantly by women in local communities. The article also discusses the physical, mechanical and chemical properties of piassava, highlighting how these characteristics influence its use in composites and other materials. Studies show that the compressive and flexural strength of piassava composites can be optimized through treatments that improve adhesion between the fibre and the polymer matrix. In addition, the challenges faced in the production chain are presented, such as the variability in fiber quality and the need for appropriate chemical and physical treatments to improve mechanical performance. Finally, the article suggests directions for future research, emphasizing the importance of piassava as a sustainable alternative in a context of growing demand for environmentally friendly materials. It concludes that, with proper development, piassava fiber can play a significant role in the construction industry and other applications, promoting more sustainable and innovative practices.
