Ichu: New Natural Fibers for Composites and its Extraction Methodology

S. Mori, E. Flores, S. Charca

Abstract. Natural fibers obtained from plants (vegetables) have been gaining great impulse in the last years, especially in the composites materials industry; besides, studies shows that the annual growth rate will be 10% in the coming years, which will trigger a gap with respect to the current offer. Due to the new legislations, that encourages the use of biodegradable materials, the preference of more users for ecological products and the tendency towards new business economic models focused on zero waste. From these, a great opportunity arises for research and development method and process of extraction of fibers from new natural resources, such as Ichu (grass). This Andean endemic grass is plentiful and its inside contains technical fibers, with potential to be extracted and used as reinforcement in composites materials. Therefore, in this research a method of extraction was designed to obtain technical fiber from Ichu (Festuca distichovaginata). Those technical fibers were used as reinforcement of polyester resin and its flexural mechanical properties were measured. In order to make comparable the properties, material index (MI) were used for strength, stiffness and density; results were compared to the literature Yute fiber composites. Finally, the process parameters were established in such a way to minimize the reference cost of production until ~1.34 USD/kg (production rate of 600 kg of fibers per day).
