Background: This era has seen outstanding achievements in materials science through the advances in natural fiber-based composites. The new environmentally friendly and sustainability concerns have imposed the chemists, biologists, researchers, engineers, and scientists to discover the engineering and structural applications of natural fiber reinforced composites. Objective: To present a comprehensive evaluation of information from 2000 to 2018 in United States patents in the field of natural fibers and their composite materials. Methods: The patent data have been taken from the external links of US patents such as IFI CLAIMS Patent Services, USPTO, USPTO Assignment, Espacenet, Global Dossier, and Discuss. Results: The present world scenario demands the usage of natural fibers from agricultural and forest byproducts as a reinforcement material for fiber reinforced composites. Natural fibers can be easily extracted from plants and animals. Recently natural fiber in nanoscale is preferred over micro and macro scale fibers due to its superior thermo-mechanical properties. However, the choice of macro, micro, and nanofibers depends on their applications. Conclusion: This document presents a comprehensive evaluation of information from 2000 to 2018 in United States patents in the field of natural fibers and their composite materials.

Structural Applications

The available potential plant waste could be worthy material to strengthen polymers to make sustainable products and structural components. Therefore, modeling the natural fiber polymeric-based composites is currently required to reveal the mechanical performance of such polymeric green composites for various green products. This work numerically investigates the effect of various fiber types, fiber loading, and reinforcement conditions with different polymer matrices towards predicting the mechanical performance of such natural fiber composites. Cantilever beam and compression schemes were considered as two different mechanical loading conditions for structural applications of such composite materials. Finite element analysis was conducted to modeling the natural fiber composite materials. The interaction between the fibers and the matrices was considered as an interfacial friction force and was determined from experimental work by the pull out technique for each polymer and fiber type. Both polypropylene and polyethylene were considered as composite matrices. Olive and lemon leaf fibers were considered as reinforcements. Results have revealed that the deflection resistance of the natural fiber composites in cantilever beam was enhanced for several reinforcement conditions. The fiber reinforcement was capable of enhancing the mechanical performance of the polymers and was the best in case of 20 wt.% polypropylene/lemon composites due to better stress transfer within the composite. However, the 40 wt.% case was the worst in enhancing the mechanical performance in both cantilever beam and compression cases. The 30 wt.% of polyethylene/olive fiber was the best in reducing the deflection of the cantilever beam case. The prediction of mechanical performance of natural fiber composites via proper numerical analysis would enhance the process of selecting the appropriate polymer and fiber types. It can contribute finding the proper reinforcement conditions to enhance the mechanical performance of the natural fiber composites to expand their reliable implementations in more industrial applications.

Cutting Out

Today’s technological innovations call for continual improvement in the field of material science to substitute the heavy structures with lightweight materials without compromising the strength. For this purpose composite materials (combination of two or more materials) are developed. The incorporation of natural fibers as reinforcing agent in both thermoset and thermoplastic polymer composites has gained increasing applications both in many areas of engineering and technology. A variety of natural fibers based polymer composite materials have been developed using modified synthetic strategies to extend its application from automotive to biomedical fields. The eco friendliness and reduction in wear and tear aspects in machineries with the use of natural fiber composites also has been captured in this paper. This paper is an earnest compilation of the data regarding a variety of natural fibers, their physical and mechanical properties, their resilience and strength. Considerable effort has been put in bringing the data on various natural fiber composites in one place by cutting out the details from various sources so as to make it as a ready reckoner for any researcher for future research in this area.

Mechanical And Tribological Characteristics

In the framework of green materials, in recent years, natural fiber composites attracted great attention of academia and industry. Their mechanical and tribological characteristics, such as high strength, elasticity, friction, and wear resistance, make them suitable for a wide range of industrial applications in which issues regarding a large amount of disposal are to be considered since their environmental friendliness gives them an advantage over conventional synthetic materials. Based on the recent and relevant investigations found in the scientific literature, an overview focused on the tribological characteristics of composite materials reinforced with different types of natural fibers is presented. The aim is to introduce the reader to the issues, exploring the actual knowledge of the friction and wear characteristics of the composites under the influence of different operating parameters, as well as the chemical treatment of fibers. The main experimental tribological techniques and the main used apparatus are also discussed, with the aim of highlighting the most appropriate future research directions to achieve a complete framework on the tribological behavior of many possible natural fiber composite materials.

Empirical model for predicting fatigue damage behavior of composite materials developed recently has been applied to composite materials made of different fibers in various configurations: carbon and glass fiber noncrimp fabric reinforced epoxy composites, chopped strand mat glass fiber-reinforced polyester composites, randomly oriented nonwoven hemp fiber-reinforced polyester composites, and glass/hemp fiber-reinforced polyester hybrid composites. The fatigue properties were evaluated in tension–tension mode at stress ratio R = 0.1 and frequency of 1 Hz. The experimental fatigue data were used to determine the material parameters required for the model. It has been found that the model accurately predicts the degradation of fatigue life of composites with an increase in number of fatigue cycles. The scope of applicability of this model has thus been broadened by using the fatigue data of natural fiber and noncrimp fabric composites.
