Introduction to NFRPC and Applications Introduction Natural fiber reinforced polymer composites (NFRPC) are the materials where renewable natural o fibers (such as hemp, sisal, jute, kenaf, flax, etc.) are used as reinforcing material (fillers) for different kind of polymer matrices (thermoplastics, thermosettings, and biopolymers) to obtain high performance composites. NFRPC materials recently became highly valuable materials since the reuse of waste natural fibers o as reinforcement for polymer is sustainable option to the environment. The natural fibers have the advantage that they are renewable resources and have marketing o appeal as they are cheap, renewable, partially recyclable and biodegradable. Applications As environmentally attractive materials, natural fiber composites have been proven as an alternative o to the glass reinforced or carbon reinforced polymer composites that can utility in different applications like automotive, aerospace, construction, packaging, electronics, sports etc. For sources of information, please refer to Appendix 1 3
Growth Prospects for NFRPC The NFRPCs market was worth USD 3.36 Billion, in 2015, and is projected to reach USD 6.50 Billion in 2021, expected to register a CAGR of 11.68% between 2016 and 2021. Government regulations and huge demand of green composites will drive the NFRPC s market. North America dominated the global NFRPCs market in 2017 followed by Asia-Pacific and Europe and is expected to dominate the market during 2018-2023 due to high demand from the construction industry. The market dominance of the non-wood fiber segment is due to widespread applications of the bast fibers (flax, hemp, kenaf, jute, mesta, ramie, rosella, isora). Germany is one of the largest producers of automobiles and a major importer of hemp in Europe. China dominated the Asia Pacific market and is likely to continue dominance over the coming years. The companies in the industry are highly integrated from the manufacturing to distribution of finished products to various locations. Advanced Environmental Recycling Technologies, Inc. (U.S.), FlexForm Technologies (US), Procotex Sa Corporation Nv (Belgium), Tecnaro Gmbh. (Germany), UPM Biocomposites (US), and Trex Company, Inc (US) are some of the key players in the industry.
