Assessment of Ichu Fibers Extraction and Their Use as Reinforcement in Composite Materials

This paper describes the research conducted to develop an optimal methodology to extract useful fibers from the “Ichu” grasses which can be used as reinforcement of polyester resin. Laminates were manufactured and their flexural properties were characterized as well as the optimal fiber properties. Results show that for this kind of materials, the mechanical and retting treatments are insufficient to remove lignin from the raw material state; on...
