Sustainable Fiber-Reinforced Composites: A Review

Sustainable fiber reinforced polymer (FRP) composites from renewable and biodegradable fibrous materials and polymer matrices are of great interest, as they can potentially reduce environmental impacts. However, the overall properties of such composites are still far from the high-performance conventional glass or carbon FRP composites. Therefore, a balance between composite performance and biodegradability is required with approaches to what one might call an eco-friendly composite. This review provides an overview of sustainable FRP composites, their manufacturing techniques, and sustainability in general at materials, manufacturing, and end-of-life levels. Sustainable plant-based natural fibers and polymer matrices are also summarized, followed by an overview of their modification techniques to obtain high-performance, multifunctional, and sustainable FRP composites. Current state-of-the-art mechanical and functional properties of such composites are then surveyed and provide an overview of their potential applications in various industries, including automobile, aerospace, construction, medical, sports, and electronics. Finally, future market trends, current challenges, and the future perspective on sustainable natural FRP composites are discussed.

Automated summary

Sustainable fiber reinforced polymer (FRP) composites from renewable and biodegradable materials are of interest due to their potential to reduce environmental impacts, but their performance is still inferior to conventional glass or carbon FRP composites. This review provides an overview of sustainable FRP composites, including manufacturing techniques, sustainability considerations, and potential applications in various industries. The review also discusses future trends, challenges, and the outlook for sustainable natural FRP composites.
